Abstract:
Medicine, like all other fields, is subject to trends. In recent years, trends towards "alternative healing" have emerged on top. Perhaps the reason for this trend is that medicine has failed to provide cures for so many afflictions without having unbearable side effects, or perhaps the reason is that medicine has advanced so much that attempts to create medicines that are less harmful than synthesized medicines have resulted in this natural trend. Whatever the reason, the fact remains that vitamin supplements, herbal foods, and "natural" drugs claiming to do what modern medicine has found difficult to accomplish. One type of "alternative healing" is called Apitherapy. Apitherapy is defined as "the healing use of the products of the honeybee hive". Much of apitherapy is based on the properties of bee venom, though there are other byproducts (propolis, royal jelly, wax, honey and pollen) which have claimed to be beneficial. The major reason this therapy has come to light is because bee venom is an anti-inflammatory affect, as well as other agents which stimulate the body's immune system. Pure bee venom (Apitox) has been tested and found to be safe in humans and animals by the International Pain Institute. The byproducts of honeybees seem to have a lot of potential for effective treatment of many medical conditions. One example would be propolis. Propolis seems to have antibiotic properties. It is much better antibiotic than chemical antibiotics because it only kills the harmful bacteria in the body, whereas chemical antibiotics kill all bacteria in the body. There are even claims that it has been proven that propolis can even kill bacteria that have become resistant to other antibiotics. Royal Jelly is another compound that is supposed to have beneficial effects and have boosting energy to treating kidney disease, even boosting sex drive. Veterinary apitherapy as complementary and alternative veterinary medicine is an inclusive term that describes treatments, therapies, and modalities that are not accepted as components of main-stream veterinary education or practice, but that are performed on animals by some practitioners. Bee products contain a vast spread of pharmacologically-active ingredients and each one has its own unique combination and properties. Recognized actions include anthelmintic, anti-catarrhal, anti-emetic, anti-inflammatory, anti-oxidant, anti-bacterial, anti-fungal, anti-spasmodic, astringent, diuretic, expectorant, sedative, stimulant and tonic. In our research and clinical background, we have used bee products to solve some animal pathologic problems such as mastitis in dairy herds, dermatology in carnivores, surgery, burn and wound management etc.

She has completed several courses like CCRP in 2012 from University of Tennessee, ESAVS-Rehabilitation and Physiotherapy of Small Animals in 2010 and Course of traumatologyorthopedic rehabilitation in 2012.
Abstract:
This study intended to adjust and apply a functional neurorehabilitation (FNR) protocol with balance training for dogs with peripheral vestibular syndrome (PVS). These protocols intended to stimulate neuroplasticity of the vestibular system, promoting static balance; and also of the central nervous system, promoting dynamic balance. According that and in order to eliminate all empirical evaluation was created a pioneer scale in veterinary medicine – a balance scale, which represents an analogy of the human’s medicine balance scale (Berg Balance Scale). This scale evaluates the ability of keeping active stance, sit after standing, standing after sitting, walking in strait line and in circles, go up and downstairs and finding balance after dislocation of the gravity center. This scale showed to be essential evaluating and monitoring these dogs, avoiding clinical discharge of only compensated dogs instead of rehabilitated. To prove its usefulness, this scale was applied to a group of 21 dogs with PVS, being successful not only to evaluate and monitor them but also to prove that application of FNR protocols with balance training was more beneficial than the administration of corticosteroids or the application of only basic treatment. It was also showed that the administration of corticosteroids does not have benefits in the final performance.

Abstract:
This study was conducted on horses with strangles for evaluation serum concentration of Vitamin C (Vit C), Vitamin E (Vit E), Selenium (Sel) and Glutathione Peroxidase (GPx) in the horses with strangles. 60 horses confirmed on the bases of clinical and laboratory signs of strangles. Blood samples tacked from jugular vein and separated serum. Sampling performed from 52 healthy horses with similar ages, feed and condition, too. Serum concentrations of Vit E, Vit C, Se and serum’s activity of GPx, enzyme measured in the samples. Mean serum levels of selenium, vitamin E, vitamin C and serum glutathione peroxidase activity in horses with strangles were reduced and except vitamin C this reduction were significant. Patient's hemoglobin level was significantly increased. Evaluate the correlation between serum selenium and serum glutathione peroxidase activity, vitamin E and hemoglobin were found in horses with strangles showed that there is a positive correlation between serum selenium and those antioxidants and with increasing serum's selenium, those serum antioxidants increased, too. In patients this antioxidant serum marker in all three was significant (r: 0.945, r: 0.561 and r: 0.893). In healthy horses correlation between selenium with glutathione peroxidase and hemoglobin was significant but with vitamin E was non-significant. In conclusion, in horses with strangles selenium, glutathione peroxidase and vitamin E reduced and supply of these antioxidants in the treatment and control of the disease is important.

Abstract:
Calcium-Magnesium and phosphorous and phasphotase alkaline enzyme is an important enzyme in body that do many physiological activities and is one of important elements of skeletan structure. On the other hand beestings is one of the important compositions for newborn calf, especially in first 6 hours. In this study, serum standards of calcium, manganese, phosphorous and alkaline phosphatase hare been examine 0, 24, 48 and 72 hours after the birth of Holstein cows. Serum standards of these elements and enzyme before and during parturition in mother have been examined. Serum standard of calcium in mother before and during parturition have been in the least amount in competition to other times (P<0.05). Serum average of this element in calf in 24, 48 and 72 hours after birth relative to mother and calf in the time of birth had meaningful increase. Serum amount of phosphorous in mother during parturition was in the least amount. In calfs after birth and 24, 48 and 72 hours after birth the phosphor increases and this increase is meaningful (P<0.05). Serum amount of Magnesium before and during parturition in mothers were low to calfs but in calfs during birth had meaning ful increase to mother(P<0.05) and this increase last from 24 to 72 hours, so that statistical comparition of serum anount of Magnesium in calfs showed statistical increase in 24, 42 and 72 hours to birth time and mother (P<0.05). the amount this enzyme before and during parturition in mothers is more than calfs. The comparision of serum amount of this enzyme showed meaningful decrease (P<0.05) in calf during birth and 24, 48 and 72 hours after birth to mother before and during parturition.

Title: Evaluation of unripe papaya (carica papaya L. ) fruits as beef tenderizer
Biography:
Abstract:
Meat tenderness is a highly desired quality trait in meat, that affect both acceptability and palatability. The objective of this study was to test the effectiveness of unripe papaya fruits as meat marinade. Two muscles (costa oculus and semitendiosus) of three beef carcasses were used. Nine unripe papaya fruits were collected and prepared in three forms (powder, extract and slices). One kg of each muscle from each carcass was used. Four slices were cut from each muscle (each weigh 200 g and 2.5cm thick). Three incisions were made on the surfaces of the slices. Each slice was assigned for each treatment (four treatments). Two g of the powder form were scattered on the surface of each slices assigned for powder treatment. Two ml of the fruit extract were sprayed on the surface of the slice assigned for extract treatment. Nine thin fruit slices were stuffed in the incisions of the slices assigned for slices treatment and removed before cooking. The treated slices were wrapped in aluminum foil and left for one hour before cooking. Little salt was added to each slice and the cooking trays were rubbed with thin layer of vegetable oil. The cooking was done in an electric kitchen oven at 200ËšC for one hour. The cooked slices were cut into small pieces of 10 g. Six trained panelists evaluated the sensory traits (tenderness, taste and flavor) plus the number of chewings in each day (three days). The results showed a positive effect of the different forms of papaya fruits on the different traits compared with the control. There was a significant difference (P ≤ 0.05) in tenderness among the different treatments, with powder form had the highest effect followed by the slices and extract forms. Although there was no significant difference in the number of chewings due to different treatments, but still, there was a negative effect of the different forms of papaya fruits on the number of chewings compared with the control. There was no significant difference in other sensory traits among the different treatments. For high tenderness in tough meat cuts, it is recommended to use unripe papaya fruit powder.

Title: Effects of type of nutrition on the chemical composition of camel milk and urine
Biography:
D Isam Adawi Abdalla is currently working as a professor in the Department of Veterinary Medicine, University of Gezira, Sudan.
Abstract:
This study was conducted to evaluate the effect of camel nutrition on their milk and urine chemical composition. A total of 30 she camels were selected from 6 herds from two different areas. All camels were Arabian type. The she- camels were in their first to third lactation time and in their second to eighth month of lactation. The camel herds at Elmanagil area were put in naturally grazing regime which was grasses plus browsing on shrubs and trees of different types, mostly Acacias, at the time of sample collection. Those at Tambool area received normal concentrate rations containing sorghum grains, ground nut cakes, wheat bran, and dry roughages in the form of sorghum stalks and Abu 70 hay inside their fens. Milk and urine samples were collected from each camel and subjected to chemical analyses. Results showed significant differences (P < 0.05) in minerals content of both milk and urine of the two treatments. As for minerals like Ca, K and Mg levels in urine were found to be higher than those in milk, while Na level was higher in milk compared to that in urine. The mineral contents in the urine of the camels of Elmanagil area were found to be significantly higher (P < 0.05) than those in the urine collected from camels of Tambool area. There was a significant (P < 0.05) differences in fat content between the two treatments. Fat content was significantly higher in the camel milk produced in Tambool area. Therefore, natural grazing and browsing of camels on trees is strongly recommended because they produce higher levels of Ca, K, Na and Mg in their milk and urine than their counterpart group of camels which were fed on concentrates.

Abstract:
A method of affinity chromatography was adopted to isolate mannosyl glycoprotein antigen from Trichinella spiralis crude larval antigen using concanavalin A (Con A) column. The selection of con A column was based on the existence of mannose sugar in T.spiralis larval extract as proved by indirect haemagglutination inhibition assay. The isolated mannosyl fraction was evaluated by ELISA and Western blot techniques for the serological diagnosis of trichinosis in experimentally infected rats. Either early in one week post infection (P.I.) or in the late stage, six weeks P.I., the isolated mannosyl fraction proved higher potency in the diagnosis of rat experimental trichinosis than crude extract by ELISA. The isolated mannosyl fraction resolved into four bands of 65KDa, 54KDa, 30 KDa and 11KDa compared with multiple bands of crude extract as observed by SDS-PAGE. A 30 KDa mannosyle glycoprotein(s) isolated from T.spiralis crude larval extract proved potentials in early as well as late diagnosis of experimental trichinosis in rats as proved by western blot.

Abstract:
The present study was undertaken in an effort to furnish information and materials for investigating control of babesiosis in sheep. Sonicated erythrocytes infected with Babesia ovis Egyptian strain was subjected to ion exchange chromatography. The proteins were fractionated into two purified fractions (unbound & bound). Sodium dodecyl sulphate poly-acrylamide gel electrophoresis (SDS-PAGE) fractionation of the crude sonicated antigen and the two purified fractions showed obvious qualitative and quantitative differences. The two purified fractions were used as immunogens for two groups of sheep using Freund's adjuvants in two successive doses. The two immunized groups plus a control one were challenged with 2.5 X 105 cryo-preserved infected erythrocytes with a homologous strain of Babesia ovis. Blood samples were collected for assessment of packed cell volume and parasiteamia percentage. The indirect fluorescent and immuno-blotting techniques were used for evaluation of immunization process. All animals in immunized groups were protected against infection, when compared with those in control group.

Abstract:
Several Campylobacter species are known to be pathogenic to humans, with Campylobacter jejuni being the main leading cause of campylobacteriosis worldwide. The present investigation aimed to detect C. jejuni from chicken, water, milk and milk products and humans among 4 Egyptian Governorates (Cairo, Fayoum, Minya and Qalubiya) using conventional method and PCR. This study spots light on this concept to indemnify zoonotic hazard of C. jejuni by molecular characterization and indirect fluorescent of Egyptian isolates from both chickens and human in contact. From various Egyptian governorates. Samples from both symptomatic consumers with history of chickens poisoning and chicken handler. Also Samples as water, milk and milk products were subjected to standard phenotypic identification of C.jejuni, and subsequently immunofluorescent technique (IFT) identification and genetic amplification by PCR using specific primers of hipO gene. It is clear that C. jejuni could be detected from chicken (38.6 %), human stool (33.3%), water samples (30%), total milk and milk products samples (7.9%). While the percentages were chicken (80 %), water (76.7 %), milk and its products (72.5 %) and human (76.3 %) usig PCR. PCR was definitive, reliable, and facilitated rapid identification of C. jejuni to the species level. It concluded that poor hygiene and sanitation in poultry farms could explain this high level of prevalence of C. jejuni among the examined samples. A high risk score for Campylobacter jejuni in chicken was obtained in Egypt . This result may contribute to development of food safety management strategies. Key efforts should be made to control the risk of Campylobacter jejuni in chicken and milk and milk products in Egypt., especially in chick breeding and chicken preparation processes.

Title: Molecular characterization of Campylobacter jejuni and Campylobacter coli in chicken in Egypt
Biography:
Ghanem H E A has been pursuing his MVSc in Poultry Diseases in Cairo University.
Abstract:
Campylobacter lives in the intestines of birds (specifically poultry) and other animals. It can be found in water, food, or surfaces that have been contaminated with the feces of infected birds. This work was done to investigate the molecular characterization of C. jejuni and C. coli isolated from rectal swabs of chicken, intestinal content, gizzard, liver, eggs, water and ration from chicken farms. We collected 498 samples from chicken (n=143) broilers and (n=355) layers at different localities. All samples were examined by conventional methods for isolation and identification of Campylobacters. Samples were subjected to standard phenotypic identification of C.jejuni and C. coli by PCR using specific primers of hippuricase gene. The prevalence of Campylobacter isolate was 21.89%; in rectal swabs 23.77%, intestine 24 %, liver 23 %, 21.48% in eggs, 12% water and 6.67% in ratio respectively. Out of 109 identified isolates, 81(16, 27%) C. jejuni isolates were higher than 28(5.62%) C.coli. A multiplex-PCR method was developed for the detection of C. jejuni and C. coli. Primers were the hippuricase gene (hipO) C. jejuni at 323bp and (C. coli glyA) characteristic of C.coli at 126bp in chicken isolates in Egypt. The virulence genes of C. jejuni (FlaA, virB11) have shown at 855 bp and 494 bp respectively. But the cytolethal distending toxin (cdtB and cdtC) of C. jejuni have shown at 495 bp and 555 bp respectively, indicating the virulence of the isolates. The results of the present study showed that all analyzed isolates of C. jejuni and C. coli contained the flaA gene. On the other hand, the virB11 gene was present only in 10 of 81 of the analyzed isolates, whereas most of the strains contained the cdt genes. Finally, we concluded that PCR detection of Campylobacter virulence can be utilized as a simple and rapid tool to discriminate stains and we need devise effective therapeutic and preventive strategies against Campylobacter infection in chicken.

Abstract:
Q fever is a zoonotic disease caused by the bacterium Coxiella burnetii. Prevalence in farm animals is important to public and animal health. The aim was to investigate the presence of C. burnetii in cattle, sheep and goats. We collected 360 samples consisted of pooled milk and serum 180 of each from dairy cattle (n=180) dairy goats (n=60) and dairy sheep (n=120) from Qaluobia, Monofia, Gharbia and Kafr ElSheikh Governorates. All samples were examined by indirect immunofluorescent antibody test (IFAT) for IgG antibodies against C. burnetii phase II antigen. The prevalence of antibodies in dairy herds was 22.5 % with large regional differences. The study revealed that antibodies against C. burnetii in cattle raw milk and sera were 14.44% and 31.11% respectively, in goat raw milk and sera were 26.67% and 46.67% respectively and in sheep raw milk and sera were 21.67% and 33.33% respectively.
These results denoted that the apparently healthy cattle, sheep and goats are an important reservoir of C.burnetii infection. Coxiella burnetii is shed in milk of the infected animals; therefore, their milk should not be consumed raw or sold unpasteurized directly to the consumers. Pasteurization milk at 145° F (63° C) for at least 30 minutes or at 161° F (72° C) for 15 seconds is sufficient to C. burnetii, as well as other pathogens that can be present in raw milk.
Finally, we conclude that it is of utmost importance to avoid contact with the placenta, birth products, fetal membranes, and aborted fetuses of sheep, cattle, and goats. Eat and drink only pasteurized milk and milk products. Further investigations must be done for C. burnetii infection in the aborted cases of farm animals.

Title: Protective effects of urtica dioica seed extract in aflatoxicosis: histopathological and biochemical findings
Biography:
Abstract:
The ameliorative potential and antioxidant capacity of an extract of Urtica dioica seeds (UDS) was investigated using histopathological changes in liver and kidney of broiler, measuring serum marker enzymes, antioxidant defence systems and lipid peroxidation (malondialdehyde (MDA)) content in various tissues of broilers exposed to aflatoxin (AF). A total of 32 broilers were divided randomly into 4 groups: control, UDS extract-treated, AF-treated and AF+UDS extract-treated. Broilers in control and UDS extract-treated groups were fed on a diet without AF. The AF-treated group and AF+UDS extract-treated groups were treated with an estimated 1 mg total AF/kg feed. The AF+UDS extract groups received in addition 30 ml UDS extract/kg diet for 21d. The AF-treated group had significantly decreased body weight gain when compared to the other groups. Biochemical analysis showed a small increase in the concentrations of serum aspartate aminotransferase, alanine aminotransferase, gamma glutamyl transpeptidase and lactate dehydrogenase in the AF-treated group compared to that of the control group, whereas concentrations of these enzymes were decreased in the AF+UDS group compared to that of the AF-treated group. Administration of supplementary UDS extract helped restore the AF-induced increase in MDA and reduced the antioxidant system towards normality, particularly in the liver, brain, kidney and heart. Hepatorenal protection by UDS extracts was further supported by the almost normal histology in AF +UDS extract-treated group as compared to the degenerative changes in the AF-treated broilers. It was concluded that UDS extract has a protective hepatorenal effect in broilers affected by aflatoxicosis, probably acting by promoting the antioxidative defence systems.

Abstract:
Uncontrolled diabetes mellitus (DM) is an etiological factor for recurrent pregnancy loss and major congenital malformations in the offspring. Antioxidant therapy has been advocated to overcome the oxidant-antioxidant disequilibrium inherent in diabetes. Our aims were to evaluate the protective effect of lipoic acid (LA) on fetal outcome and to elucidate changes that may be involved in the mechanism(s) implicit diabetic fetopathy. Female rats were rendered hyperglycemic using streptozocin and then mated with normal male rat. Pregnant non-diabetic (group1; n=9; and group2; n= 7) or pregnant diabetic (group 3; n=10; and group 4; n=8) rats were treated daily with either LA (30 mg/kg body weight; groups 2 and 4) or vehicle (groups 1 and 3) between gestational days 0 and 15. On day 15 of gestation, the rats were sacrificed, and the fetuses, placentas and membranes dissected out of the uterine horns. Following morphological examination, the fetuses, placentas and membranes were homogenized, and used to measure cyclooxygenase (COX) activities and metabolisms of prostaglandin (PG) E2 (PGEM) and PGF2ï¡ (PGFM) levels. Maternal liver and plasma total glutathione levels were also determined. Supplementation of diabetic rats with LA was found to significantly (p<0.05) reduced resorption rates in diabetic rats and increased mean fetal weight compared to vehicle-treated diabetic (V-TD) group. Treatment of diabetic rats with LA (LA-TD) leads to a significant (p<0.05) increase in liver and plasma total glutathione, in comparison with V-TD rats. Decreased levels of PGEM and elevated levels of PGFM in the fetuses, placentas and membranes were characteristic of experimental diabetic gestation associated with malformation. LA treatment to diabetic mothers failed to normalize levels of PGEM to the vehicle–treated control rats. However, the levels of PGEM in malformed fetuses from LA-TD mothers was significantly (p< 0.05) higher than those in malformed fetuses from V-TD rats. LA can reduce congenital malformations in the offspring of diabetic rats at day 15 of gestation. Thus, LA treatment did not completely prevent the occurrence of malformations, other factors, such as arachidonic acid deficiency and altered prostaglandin metabolism may be involved in the pathogenesis of the diabetes-induced congenital malformations.

Title: Effect of dietary levels of safflower seeds and molasses supplementation on broiler chickens performance and carcass traits
Biography:
Abstract:
This study was Carried out to evaluate the inclusion of safflower seeds supplemented with molasses on broiler chickens performance and carcass traits. A total of 108 cobb strain unsexed one day old broiler chicks into six isocaloric and isonitrogenous diets and each contained three replicates (6 birds/replicates) in a completely randomized design. Dietary treatments were: No additives as control (A), 5% safflower seeds without molasses (B), 10% safflower seeds without molasses (C), 5% safflower seeds with 3% molasses (D), 10% safflower seeds with 3% molasses (E) and 3% molasses without safflower (F) Feed and water were provided ad lib till the termination of the trial after 42 days. Parameters measured were feed intake, body weight gain, feed conversion ratio (FCR), relative weight of internal organs (dressing percentage, liver, gizzard, abdominal fat, heart and shrink percentage) and meat proximate analysis. The result revealed that birds fed 5% safflower seeds with 3% molasses consumed higher feed. However, no significant differences were observed between dietary groups for body weight gain, FCR, pre slaughter, hot carcass, cold carcass and relative weight of liver, abdominal fat, gizzard and heart. Inclusion of 10% safflower seeds without molasses and 5% safflower with 3% molasses decreased shrink relative weight. Meat analysis showed that birds fed A, CC, E and F recorded significant (p<0.05) higher protein content. Moreover, non significant difference were observed for moisture content, ash content, ether extract and fiber content. In conclusion, safflower seeds with molasses could be effective in enhancing broiler performance and decreasing shrink relative weight.

Title: Novel biomarkers in urinary tract infection in dairy cows
Biography:
Abstract:
The goals of this study were to investigate the level of acute phase proteins in dairy cows with urinary tract infection (UTI) and to evaluate their diagnostic and prognostic value. Eighty-four lactating cows with clinical and laboratory evidence of UTI and 15 healthy controls were included in this study. Serum samples were evaluated for the levels of Haptoglobin (Hp), serum amyloid A (SAA), fibrinogen (Fb), α1-Acid glycoprotein (AGP), total protein, and globulin. The diagnostic and prognostic performance of each parameter was evaluated by estimating the area under receiver operating characteristics curve (AUROC). Escherichia coli and Corynebacterium spp. were the primary bacteria associated with UTI. The levels of serum Hp, SAA, Fb, AGP, total protein, and globulin were significantly higher in UTI cows. Successfully treated cows (n=51) had lower levels of Hp, SAA, AGP, total protein, and globulin than non-responsive cows. Overall, Hp, SAA, Fb, and AGP showed comparable diagnostic accuracy (AUROC ranged from 0.93 to 0.98). Both Hp and SAA showed high accuracy in predicting treatment response (AUROC>0.95), whereas Fb level was of no prognostic value (AUROC=0.48). From this study, acute phase proteins levels can be used as markers for UTI in cows and higher levels of Hp, SAA and AGP are related to poor treatment response.

Abstract:
The camel Population in the Sudan is about 2.5 million heads and camel pox disease is wide spread and it leads to high economical losses, disease control is also important for camel export. Camel pox vaccine was s produced using a master seed lot which was donated by PANVAC and cultivated on a continuous cell line of African green monkey kidney cell (VERO) and tested for the first time in Sudan. The vaccine was produced according to OIE manual and subjected to potency, safety and efficacy tests in the host animals. The identity test for vaccine virus and locally isolated wild type virus was done as the first step using AGID, VN, and PCR tests. Moreover, sterility test was done for bacterial, mycoplasmal and fungal contaminations. The working seed bank was further tested for safety by inoculation of 6 susceptible camels with 10x the recommended field dose of camel pox vaccine (104 TCID50) using the subcutaneous route .The vaccine efficacy was also demonstrated in 14 healthy susceptible camels. Thus, 10 camels were vaccinated by 103 TCID50 by S/C route and 4 were inoculated with phosphate buffer saline (PBS) and kept as control. The vaccine was safe and the inoculated animals remained healthy without any adverse reaction, neither signs of illness nor a rise in rectal temperature were recorded for up to 40 days post vaccination. Seromonitoring of the vaccinated camels revealed production of protective immune response after the fourth week of vaccination, while control camels did not seroconvert. Forty days post vaccination all the vaccinated and control groups were challenged by 105.6 TCID50 S/C with camel pox. Wild type virus, only the control group developed very severe clinical signs and fever 40oc with generalized and localized camel pox lesions, while the vaccinated groups withstood the test without death or clinical signs. These results confirm that the produced vaccine batch was safe, and immunogenic under laboratory and field trials, which was conducted using 300 camels.

Abstract:
Cockroaches are cosmopolitan and omnivorous insects which can ingest feces from dogs therefore, it has been suggested that cockroaches could disseminate Toxocara canis eggs. The aim of this study was to determine if Periplaneta americana cockroaches are capable of disseminating infective eggs from T. canis (ieTc). They were used 100 groups of infected cockroaches with approximately 500 ieTc/cockroaches were used (n=2). A direct microscopic test with feces of each group of cockroaches was made daily to determine the number of ieTc/released in feces. Feces from other 60 infected cockroaches were employed to inoculated rats. Seven groups of rats (n=5) were used; rats of groups 1,2,3,4 and 5 were inoculated with 5mg of feces from days 1,2,3,6 and 10 post-infection respectively; group 6 and 7 served as positive and negative controls respectively. Rats were euthanized at day 20 post-infection; brain, lung, liver and kidney were taken and artificially digested to count the quantity of larvae present in them. Finally, serum levels of anti-Toxocara antibodies were measured through ELISA test. The cockroaches released ieTc in feces during the first six days pos-infection. Rats inoculated with cockroaches –feces up to 6 days pos-infection had larvae in different organs (mainly in brain and lung) and higher specific antibodies levels than the control group (p<0.01). These results show insect-mammal T. canis transmission, and it suggests than cockroaches could be a good disseminator of T. canis in nature.

Abstract:
The aim of this study was to investigate the antioxidant properties and protective role of honey, considered a part of traditional medicine, against carcinogen chemical aflatoxin (AF) exposure in rats, which were evaluated by histopathological changes in liver and kidney, measuring level of serum marker enzymes, antioxidant defense systems, and lipid peroxidation content in liver, erythrocyte, brain, kidney, heart and lungs. For this purpose, a total of eighteen healthy Sprague-Dawley rats were randomly allocated into three experimental groups: A (Control), B (AF-treated) and C (AF+honey-treated). While rats in group A were fed with a diet without AF, B, and C groups received 25 µg of AF/rat/day, where C group additionally received 1 mL/kg of honey by gavage for 90 days. At the end of the 90-day experimental period, we found that the honey supplementation decreased the lipid peroxidation and the levels of enzyme associated with liver damage, increased enzymatic and non-enzymatic antioxidants in the AF+honey-treated rats. Hepatoprotective and nephroprotective effects of honey is further substantiated by showing almost normal histological architecture in AF+honey-treated group, compared to degenerative changes in the liver and kidney of AF-treated rats. Additionally, honey supplementation ameliorated antioxidant defense systems and lipid peroxidation content in other tissues of AF+honey-treated rats. In conclusion, the present study indicates that honey has a hepatoprotective and nephroprotective effect in rats with experimental aflatoxicosis due to its antioxidant activity.

Title: Mechanisms involved in quinolone resistance of Mycoplasma capricolum subsp. capricolum
Biography:
Juan Tatay-Dualde is doing his PhD studies at the Department of Animal Health at the University of Murcia.
Abstract:
Mycoplasma capricolum subsp. capricolum (Mcc) is one of the contagious agalactia (CA) causatives agents. Owing to the lack of other effective methods for control and prevention, antimicrobials are the most commonly selected treatment against this microorganism, being quinolones widely used. Quinolones interact with the bacterial DNA gyrase and topoisomerase IV, both implicated in DNA replication. DNA gyrase is compound by subunits A and B which are codified by gyrA and gyrB genes. Besides, topoisomerase IV is codified by parC and parE genes, and all of them (gyrA, gyrB, parC and parE) are known as the Quinolone Resistance Determining Regions (QRDR). Prior studies have demonstrated the influence of those genes in the phenotypic resistance to quinolones in several species of Mycoplasma spp. Nevertheless, molecular mechanisms involved quinolone resistances in Mcc are still unclear. Therefore, the aim of this study was to assess changes at the QRDR region in connection with quinolones resistance. For that purpose, enrofloxacin, marbofloxacin and moxifoxacin were used to select in vitro resistant mutant. The study was carried out with two Mcc field isolates (Cap1 and Cap4) and the reference strain, California Kid (CK) (NCTC 10154) by consecutively culture at subinhibitory antimicrobial concentration. MIC values were assessed between each step and when they increased, gyrA, gyrB, parC and parE were studied. Our results showed that when MIC values increased, changes were detected in all the studied genes but parE. Thus, we found 4 amino acid changes at gyrA (Ser83Ile, Cys84Thr, Ala119Thr, His154Arg), 3 amino acid changes at gyrB (Asp426Gly, Arg447Lys, Asn465Lys) and 4 amino acid changes at parC (Asp79His, Ser80Ile/Asn, Asp84Asn, Glu150Lys). However, the amino acid and position changed differed according to the strain and antimicrobial used. Moreover, the MICs values from which we were able to detect mutations varied according to de antimicrobial used. The different changes attributable to each mutation on the MIC value may be due to different effects in the structure of the proteins and consequent changes in the affinity of quinolone. Indeed, previous studies with Ureaplasma spp, demonstrated structural changes due to amino acid changes at positions 83 and 84 of the parC gene. Besides, except for the reported change at gyrA gene position 154, all the mutations observed in our study meant changing the polarity or charge of amino acids. These changes could explain protein conformational changes and thus lower affinity with quinolones.

Title: Role of germinated feed supplementation on growth of broilers
Biography:
Abstract:
Poultry farming in India, in spite of several constraints, has progressed considerably during the last decade. Poultry production in India was confined to backyards till recently. Local breed of birds were reared for the supply of eggs and meat. The increasing demand for poultry products due to higher protein and nutritive values necessitates augmenting the supply of these poultry product. The present study has been undertaken to examine various aspects related to the growth and development of poultry production under natural conditions using natural least costly products in the country. Supplementation of germinated sorghum in the diets of broilers in place of normal maize as the grain part gives very good results in term of better growth performance of the broilers as well as the taste of the broiler meat. The experiment was conducted on 200 broiler day old chicks, which are randomly divided into five groups of 40 chicks each. The germinated sorghum was added as 25, 50, 75 and 100% of the total grain portion. Group 1 is kept as control, in group 2 the germinated sorghum was added 25% + 75% normal sorghum, group 3 the ratio is 50:50, group 4 it was 75:25 and in group 5 100% germinated sorghum is added to the feed of broilers. The live body weight and feed conversion efficiency was taken every week. It was observed that when the 50% and 75 percent germinated sorghum was added in the feed the growth rate was significantly higher than the other supplemented and non supplemented groups. Likewise the feed conversion efficiency was also significantly higher that means the bird was taken less feed but the conversion efficiency to the meat was more. On the basis of this this is concluded that the use of germinated grains give much profit because there is no use of costly growth promoters in this study.

Biography:
Abstract:
The main objectives of this study are to compare yoghurt made of goat, sheep and camel milk with cow milk yoghurt on the basis chemical composition and sensory evaluation, in addition to the effect of storage. Milk samples were collected from different farms in Shambat area, and the experiments were conducted in dairy laboratories, University of Khartoum using Lactoscan milk analyzer. The samples were taken from fresh milk and yoghurt of the different species for the comparison; also samples were taken for evaluation at 1st and 7th day of storage. Duncan's Multiple Range Test (DMRT) was used for the analysis of the data. The goat and cow milk yoghurt were significantly different at (p≤0.05) in fat (3.7 and 4.19%), respectively and in acidity (1.3 and 0.88%) respectively, while no significant differences were shown in total solids, protein and ash after the 1st day. Seven days of storage revealed significant variations (p≤0.05) in protein, total solid, ash and acidity with no significant variation in fat content. The comparison between sheep and cow milk yoghurt at the 1st day, there was a significant variation (p≤0.05) in fat, protein, total solid and acidity, and no significant variation in ash content. There was a significant variation (p≤0.05) in protein, total solid, ash and acidity percentage, and no significant variation in fat content at the 7th day of storage. For the camel and cow milk yoghurt at the 1st day there was significant variation (p≤0.05) in fat, total solid, ash and acidity content, also there was no significant variation in protein content at the 7th day. When comparing fresh milk and yoghurt in the same species, a significant difference (p≤0.05) was found in total solid and acidity, no significant variation in fat and protein in goat and camel milk and yoghurt, and they were significantly higher in sheep yoghurt compared to sheep milk. The three species were not significantly different in ash content of fresh milk and yoghurt. Sensory evaluation of yoghurt at the first day of processing showed that the most accepted color is for goat yoghurt and the best flavor, texture and taste is for sheep yoghurt. The evaluation at 7th day of storage indicated that the accepted color for the sheep and goat yoghurt, and the best flavor and taste is for sheep yoghurt but goat yoghurt has get best texture than other samples. Further studies and research are needed to improve the quantity and quality of goat, sheep and camel yoghurt.

Biography:
Shahzad Akbar Khan is currently working as a Professor in the Department of Pathologic Sciences State University Londrina, Londrina, PR, Brazil.
Abstract:
Study on immunopathological parameters has shown alterations in different organ systems induced by ochratoxin-A (OTA). This study was designed to evaluate immunopathological responses of broiler chicks kept on different levels of OTA contaminated feed. For this purpose, one day old, 42 broiler chicks were divided into seven groups (A, B, C, D, E, F, G). Group A, was kept as control, while groups B, C, D, E , F and G were fed OTA contaminated diet at 0.1, 0.3, 0.5, 0.7, 0.9 and 1.1 mg/Kg feed, respectively, for 21 days. Relative weights of liver, kidneys, bursa, thymus and spleen were recorded at the end of experiment. Hematologic profile and histopathological alterations in liver, kidneys, spleen, bursa and thymus of chicks was determined to assess the OTA mediated damage. Serum concentration of IgY and Ig A were measured for determination of humoral immune response. Clinical signs exhibited by the chicks included severe diarrhea, dullness, depression, decrease feed intake, increase water intake and rippled feathers. Gross pathological lesions on liver and kidneys included lighter in coloration, friable and hemorrhagic. A significant increase (p<0.05) in the relative weight of kidneys and liver was observed in OTA fed chicks group C, D, E, F and G, while significant decrease (p<0.05) in weight of bursa and thymus was observed in all OTA treated groups, similarly, significant reduction (p<0.05) in relative weight of spleen was observed in OTA treated groups F and G. Histologically, liver and kidneys of chicks showed degenerative and infiltrative changes while spleen, bursa and thymus showed marked reduction of lymphoid cell. Hematological profile indicated significant decrease (p<0.05) in hematocrit, erythrocytes, hemoglobin, leukocytes and lymphocytes, while significant increase (p<0.05) in heterophils and monocytes. Eosinophils were detected in chicks treated with higher doses of 0.9 and 1.1 mg/kg of feed. Level of IgY and IgA was significantly decreased (p<0.05) in all OTA treated groups in a dose dependent manner. The findings of this study suggested that there were immunopathological effects from OTA in the chicks kept on low to higher doses of OTA-contaminated diet even OTA @ 0.1mg/kg of feed.

Title: Biochemical and hormonal changes in serum of dairy cattle suffered from infertility
Biography:
Abstract:
The present study was conducted to evaluate the importance of some metabolic profile tests in diagnosis and prognosis of infertile cows suffering from smooth inactive ovaries and cystic ovaries. In addition to determining serum biochemical and hormonal changes associated with these problems. The main complaint was delayed estrus and lower conception rate. Twenty-three dairy cows were divided into three groups according to rectal palpation selected from different localities at El-Farafra and El-Dakhla Oases, New Valley governorate. The first group (n=12) showed small and smooth ovaries (clinically showing anestrum). The second group (n=5) had cystic ovaries (showed repeat breeder). The last two infertile groups fed Berseem hegazy (Alfalfa) only or Berseem hegazy and Boos or Tibin. The third group, control healthy, fertile cows (n=6) exhibited a physiological estrous cycle and showing regular conception rate. They were fed balanced ration (Berseem; Trifolium alexanderinum), concentrates, corn, tibin. Blood samples were collected from jugular vein puncture from all animals for determination of serum biochemical parameters, micro- and macro- elements and hormonal analyses. Representative samples of soil, plants and wells' water from different studied localities were collected for determination of available phosphorus, iron, zinc, manganese and copper. Estimation of electrical conductivity in the water was also done. Analysis of the data revealed that anestrum cows had significantly low levels of phosphorus, sodium, copper, selenium and iron. However, cows suffered from cystic ovaries had significantly low phosphorus, selenium and iron levels. The two infertile groups had significantly higher serum calcium/phosphorus ratio, aspartate aminotrasferase activity and estrogen. There was a marked decrease in serum total proteins, blood urea nitrogen, progesterone concentrations in both infertile groups. Serum cholesterol, T3 and T4 were markedly decreased, while serum triglycerides were increased in cystic ovaries group. Analysis of the soil and plants revealed low phosphorus concentrations and high levels of some trace elements' content. In conclusion, absence of balanced ration, deficiency of phosphorus in soil and feed, and presence of phytoestrogenic isoflavones led to dysfunction of the ovaries in the examined dairy cows with subsequent low in conception rate and high incidence of infertility. Soil must be treated with phosphate fertilizers. Berseem hegazy must be supported by adding concentrates and mineral mixture. containing sodium dihydrogen phosphate, selenium and vitamins.

Title: Prevalence of Bovine Trypanosomosis in and around Nekemte Areas, East Wollega Zone, Ethiopia
Biography:
Abstract:
A cross-sectional study was conducted from November 2010 to April 2011 to determine the prevalence of trypanosomosis and to identify the prevailing species of trypanosomes in cattle present in and around Nekemte. Blood sample were collected from ear vein of 400 cattle and then examined using thin and thick smear method followed by Buffy coat examination. Anemic status was determined by Packed Cell Volume (PCV). Out of 400 samples were examined, 36 (9%) were positive, out of which 26 (0.065%) had Trypanosoma vivax and 10 (0.025%) had T. congolense. The mean PCV of the infected animal is 19.36 and that of non-infected animal is 27.54, which indicates a significant difference between these animals. Trypanosomosis is a fatal and economically devastating disease and the major constraint to production by causing loss of the livestock. Therefore, the better strategies to prevent this disease includes: avoidance of animals from tsetse-infested areas, tsetse fly control by using different scientific methods (such as, sterile insect technique, use of acaricides), prophylactic use of trypanocidal drugs, keeping of trypanoresistant breeds and good husbandry practice for the prevention of the disease.

Abstract:
In cellular therapy field, the impact of confluence degree to harvest or differentiate BMMSCs and the effect created by cell-to-cell contact remains controversial. Therefore, the impact of 20, 50, 70, 80 and 100% confluences on BMMSCs proliferation properties, ERK and p-ERK proteins expression and glucose consumption rate was studied. Confluence-associated osteogenic differentiation efficiency was identified by determining calcium deposition, alizarin red staining, Alkaline phosphatase activity and osteopontin and osteocalcin genes expression. There was a correlation between confluence% and density. Viability was declined at the lower and higher confluences. The highest CFU-F, Brd-U uptake and population doubling were obtained at 80% confluence. ERK band intensity in 100% confluent BMMSCs was lower. Bands of p-ERK were highly detectable at 70% and 80% confluences. Glucose consumption rate at 70% and 80% confluences were higher than at 20% and 100% confluences. Although higher osteogenic differentiation appeared at 80% confluence, it was also extended at 100% confluence. Osteopontin gene expressed among all confluences while osteocalcin gene was highly expressed in 70% confluence. We concluded that the optimum seeding density for maximal expansion and harvesting purposes is 80% confluence and up to 100% confluence for osteogenic differentiation to trigger the process to be more cost effective.

The aim of this study was to compare the acceptability of 3 different cephalexin-containing antibiotics: Rilexine®75 mg (Virbac, France), Therios®75 mg (Ceva, France) and Cefaclear® 75 mg (Kyoritsu, Japan). 30 cats (domestic shorthairs, ≥9 months of age and average body weight: 3.6 kg) were divided into 3 groups and received a single administration of each product, in a different, randomized order per group (random cross-over) for 3 days: on days 1, 2 and 3, Group 1 received Rilexine®, Therios® and Cefaclear® respectively, Group 2 received Therios®, Cefaclear® and Rilexine®, respectively and Group 3 received Cefaclear®, Rilexine® and Therios®, respectively. The person giving the tablet was blinded concerning the products, which were named with letters A, B or C. The tablet was put in a bowl for 2 minutes and then presented in the hand of the experimenter (with glove) for 30 seconds if the cat did not take it in the bowl. A monitoring sheet with informations concerning intake (bowl, hand or no intake) and consumption (total, partial or none) for every cat was filled each day. A general mixed model for correlated data assuming a binomial distribution and a logit link was used to compare the 3 groups. Pair wise comparisons were performed at the 5% significant threshold. The number of cats (%) taking the product (in bowl or hand) were: 26/30 (86.7%), 20/30 (66.7%) and 23/30 (76.7%) for Rilexine®, Therios® and Cefaclear®, respectively. The number of cats (%) consuming the whole product were: 23/30 (76.7%), 20/30 (66.7%) and 20/30 (66.7%), respectively. Although not significantly different, more cats took and consumed Rilexine than the 2 other products, suggesting a better acceptability of Rilexine. In conclusion, Rilexine® is taken and consumed spontaneously by most cats. This good acceptability should allow good treatment compliance, which is of interest for long-term management of skin infections, for example.

Title: Study on diagnostic imaging in whooper swans using a digital X-ray system
Biography:
Toshihiro Ichijo is currently working as a researcher in the Cooperative Department of Veterinary Medicine at Faculty of Agriculture, Iwate University, Japan.
Abstract:
Soft X-ray equipment has been used to image birds. The purpose of this study was to acquire and examine diagnostic images in the whooper swan. The head, thorax, and wings of five swans from the Iwate Prefectural Wildlife Protection Center were imaged using digital X-ray equipment (Aero DR system; Konica Minolta, Tokyo, Japan) and an X-ray generator (Mikasa, Tokyo, Japan). The conditions were 50-55 kV, 0.5-1.0 mA, and a file focus distance of 100 cm. The image data were analyzed with the software. The images revealed that the lateral thoracic tracheal cartilage spiraled around the chest cavity and was connected to the left and right air sacs. The syrinx seemed to spiral in some sections. The soft tissues of the heart and gizzard, the pelvic, hip, leg bones and the muscles were all clearly seen. The tail anteroposterior image revealed the intestine, the shafts of the tail feathers, the feather valves, and the wing roots. Sufficient contrast resulted in clear visualization of soft tissue. The skeleton, soft tissue and cartilage were revealed well by digital X-ray imaging, suggesting applications in diagnostic imaging.

Abstract:
In cellular therapy field, the impact of confluence degree to harvest or differentiate BMMSCs and the effect created by cell-to-cell contact remains controversial. Therefore, the impact of 20, 50, 70, 80 and 100% confluences on BMMSCs proliferation properties, ERK and p-ERK proteins expression and glucose consumption rate was studied. Confluence-associated osteogenic differentiation efficiency was identified by determining calcium deposition, alizarin red staining, alkaline phosphatase activity and osteopontin and osteocalcin genes expression. There was a correlation between confluence% and density. Viability was declined at the lower and higher confluences. The highest CFU-F, Brd-U uptake and population doubling were obtained at 80% confluence. ERK band intensity in 100% confluent BMMSCs was lower. Bands of p-ERK were highly detectable at 70% and 80% confluences. Glucose consumption rate at 70% and 80% confluences were higher than at 20% and 100% confluences. Although higher osteogenic differentiation appeared at 80% confluence, it was also extended at 100% confluence. Osteopontin gene expressed among all confluences while osteocalcin gene was highly expressed in 70% confluence. We concluded that the optimum seeding density for maximal expansion and harvesting purposes is 80% confluence and up to 100% confluence for osteogenic differentiation to trigger the process to be more cost effective.
