Objective: The objective of this study was to isolate and identify Pasteurella spp. associated with pneumonic lungs showing respiratory signs of goats in Ethiopia. Materials and methods: A total of 2400 goats that were slaughtered at the Hashim&#146;s Ethiopian Livestock and Meat Export abattoir, Ethiopia were randomly selected for this cross-sectional study during the period of October 2013 to July 2014. Detail ante-mortem, and post-mortem (PM) lesions were inspected, and the suspected samples were collected aseptically from the lungs. Among 2400 goats, 31(1.29%) goats were not slaughtered because these goats showed severe clinical signs. Thus, 2369 goats were slaughtered finally. The collected samples were subjected for isolation and identification of bacterial species following conventional methods such as culture and biochemical examinations. Results: Out of 2400 goats examined, 960(40%) animals showed different abnormal respiratory signs. Based on PM findings, 16.21% (n=384/2369) lungs were found as pneumonic, of which 78.38% (n=301/384) were found to be associated with Pasteurella organism. The overall prevalence of Pasteurella organism (Mannheimia haemolytica and Pasteurella multocida) was 12.71% (n=301/2369). In this study, youngers and goats with medium body condition score (BCS) had greater probability (P<0.05) to be infected by the bacteria though there was no difference in exposure to the organism among goats from Arsi, Bale and Hararghe. On the other hand, out of 301 positive cases, 274(91.03%) were caused by M. haemolytica, and 27(8.97%) were caused by P. multocida isolates. Conclusion: Pasteurella organism especially M. hemolytica is one of the most common causes of pneumonic pasteurellosis in caprine at the study area. So, chemoprophylaxis needs to be given to small ruminants prior to transportation or other stress conditions. [J Adv Vet Anim Res 2017; 4(2.000): 147-154]

Objective: The present work was conducted on Cobb-500 broilers fed with either probiotics (Yogurt, Promax&reg;) or antibiotic growth promoters (Ciproflox&reg;, Renamycin&reg;) to assess the effects on body weight and biochemical parameters. Materials and methods: A total of 30 day-old broiler chicks were purchased and acclimatized for 7 days in the experimental shed. After initial acclimatization, the broilers were allotted into five equal groups (n=6). Group A was considered as control and was fed commercial ration and fresh drinking water. Groups B and C were fed commercial ration and probiotics (Yogurt, Promax&reg;) respectively mixed in water. Groups D and E received commercial ration and antibiotic growth promoters (Ciproflox&reg;, Renamycin&reg;) respectively with water. Body weight of each bird was recorded on day 7, 14, 21, 28 and 35. At the end of trial period, the birds were sacrificed to collect blood in order to prepare serum samples for biochemical analyses considering total cholesterol, triglyceride, high density lipids (HDL), creatinine, alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Results: Body weight in all treatment groups (B, C, D and E) was significantly (P<0.05) higher as compared to control (A) group. Total cholesterol and triglyceride levels significantly (P<0.05) decreased in probiotics treated groups as compared to control and antibiotic growth promoters treated groups. AST and ALT values increased significantly (P<0.05) in antibiotic growth promoters treated groups as compared to control whereas, these values decreased in probiotics treated groups. Creatinine levels were significantly (P<0.05) higher in antibiotic growth promoters treated groups as compared to all others groups. Conclusion: Significantly increased body weight is observed in probiotics and antibiotic growth promoters supplemented broilers. Probiotics also improve the lipid profile and other biochemical parameters as compared to growth promoter. Probiotics (like Yogurt and Promax&reg;) seem to be better choice than antibiotic growth promoters as feed supplements. [J Adv Vet Anim Res 2017; 4(3.000): 288-294]

Objective: The study was conducted to standardize the desire level of papaya latex on quality of cheese prepared from cow milk. Materials and methods: Cheese sample was prepared using whole milk collected from Dairy Farm, Bangladesh Agricultural University. This experiment was conducted on five treatments from cow milk named as sample CC1: cow control; A1: 2 drops (0.06 gm); B1: 3 drops (0.10 gm); C1: 4 drops (0.14 gm); D1: 5 drops (0.16 gm) of papaya latex. All experimental cheeses were judged by a panel of judges for organoleptic evaluation using a score card. The total solids and ash content of the different types of cheese were determined by oven drying method according to AOAC. Fat per cent, protein and acidity were determined by Babcock method, procedure and titrating with N/10 sodium hydroxide solution, respectively described by Aggarwala and Sharma. Results: There was significant difference within the overall physical score of different samples except color score. Overall score of sample B1 was highest (93.67&plusmn;1.53) and score of sample D1 was lowest (72.33&plusmn;12.01). In case of chemical analysis, the highest protein value was 17.14&plusmn;0.34% found in B1 and lowest value was 14.94&plusmn;0.16% found in D1. The highest fat value of sample B1 was 23.00&plusmn;1.00% and lowest value was 16.00&plusmn;1.00% found in C1. Highest carbohydrate was found in A1 (9.44&plusmn;2.25) and lowest in D1 (5.02&plusmn;0.04). Total solids and moisture content of cheese differed significantly (P<0.01) among the sample. On the other hand, non-significant difference was found in acidity. Conclusion: Cheese from cow milk, time on curd coagulation have significant difference (P<0.01) but non-significant difference was found in yield. Highest yield was found in sample CC1 (200.00&plusmn;5.00 gm/kg) and lowest yield was found in B1 (193.33&plusmn;2.89 gm/kg). [J Adv Vet Anim Res 2017; 4(3.000): 249-254]

Objective: This study was conducted to determine the prevalence of Salmonella in milk (farm bulk milk, raw market milk) and cheese (kareish, white soft cheese) samples that were collected randomly from farms, supermarkets, small vendors and shops in different districts of Mansoura city, Egypt. Materials and methods: A total of 100 farm bulk milk, raw market milk, kareish cheese and white soft cheese samples (25 of each) were screened for the prevalence of Salmonella spp. The Salmonella isolates were isolated and identified by conventional bacteriological techniques, which were further confirmed genetically by polymerase chain reaction (PCR) based on the presence of invA gene. Finally, the isolates were serotyped. Results: Salmonella could be detected in 15%(n=15/100) samples with a prevalence of 12%(n=3/25), 24%(n=6/25), 20%(n=5/25) and 4%(n=1/25) in raw market milk, raw farm bulk milk, kareish cheese and white soft cheese, respectively. The Salmonella isolates were serotyped into S. enteritidis 33.3%(n=9/27) which was the most frequent, followed by S. typhimurium 25.9%(n=7/27), S. heidelberg 14.8%(n=4/27), S. infantis 11.11%(n=3/27), S. tsevie 11.11%(n=3/27) and S. haifa 3.7%(n=1/27). Conclusion: The present study confirms the presence of Salmonella in milk and cheese samples in Mansoura, Egypt, indicating that the dairy products can act as potential sources of Salmonella infection. Thus, appropriate hygienic measures are suggestive for combating Salmonellosis in Egypt. [J Adv Vet Anim Res 2017; 4(1.000): 45-51]

Objective: In this study, a serological survey was conducted in unvaccinated sheep and goat populations at Pyawbwe and Meikhtila townships of Mandalay region in Myanmar to determine the seroprevalence and associated risk factors of foot and mouth disease (FMD). Materials and methods: A total of 110 sheep and 107 goat sera samples were randomly collected from Pyawbwe. Similarly, 108 sheep and 109 goat sera were collected from Meikhtila. All samples were tested for the presence of non-structural protein (NSP) specific antibodies to FMD virus (FMDV) by Ceditest FMDV-NSP Enzyme-lined Immunosorbent Assay (ELISA), and were confirmed by Liquid Phase Blocking ELISA (LPB ELISA) . Results: Overall seroprevalence was 42.4%(n=184/434) by Ceditest-NSP ELISA, and 46.8%(n=203/434) by LPB ELISA against FMDV serotype O. The presence of antibodies against FMDV serotype O was higher (P<0.01) as compared to those of serotype A and Asia-1. The seroprevalence in Meikhtila (49.77%) was higher (P<0.01) than that of Pyawbwe (35.2%). The seropositivity in sheep and goats that were in-contact (77.19%) with infected cattle and pigs was higher (P<0.01) as compared to those in-contact with non-infected animals (37.14%). Similarly, the seropositivity in sheep and goats from high animal trade areas (49.4%) was higher (P<0.05) than that of those from low animal trade areas (37.97%). Conclusion: Rearing of sheep and goats in-contact with FMDV-infected cattle and pigs, and high animal trading areas are the major associated risk factors for FMDV infection for sheep and goats in the study areas in Myanmar.

Objective: This study was carried out to investigate the effects of estradiol benzoate (EB) injection to male rabbits on glucose, total-protein, albumin, calcium concentrations and prostate tissue, and the role of prolactin as an important mediator of estrogen action in prostate. Materials and methods: Fifty four adult male rabbits were used in this study. The rabbits were randomly divided into two groups. Group A contained 36 male rabbits, which were further randomly divided into four sub-groups, three of them contained 10 rabbits and one sub-group contained 6 rabbits as control. Group B contained 18 male rabbits, which were divided randomly into three equal sub-groups. Three sub-groups of Groups A and B were treated once each on alternative day with the intramuscular injections of EB dosed at 40, 80 and 120 &micro;g/rabbit, respectively for 20 days, whereas the fourth sub-group of Group A received no estradiol, and Group B received 1 mg Bromocriptine Mesilate in addition to EB through oral route on each alternative day. Blood samples were collected for measuring glucose, t-protein, albumin and calcium levels. Prostate tissue samples were collected from all the rabbits for histological studies. Results: Glucose was significantly (P&#706;0.05) increased as a result of 80 &micro;g EB injection, while significantly (P&#706;0.05) decreased due to 40 and 120 &micro;g EB injection. Total protein significantly (P&#706;0.05) increased due to injection of 40 &micro;g EB, however t-protein was not changed due to 40 and 120 &micro;g injection. On the other hand, the results of albumin and calcium were not affected (P&#707;0.05) by EB. In prostate tissues, EB induced hyperplasia with dysplasia or dysplasia only, but this effect was mild due to inhibition of prolactin. Conclusion: The injection of EB to male rabbits increased or decreased glucose level, increased t-protein level mildly or not changed, while albumin and calcium levels were not affected. EB induced hyperplasia on prostate tissue, and this effect was reduced by prolactin inhibition indicating that prolactin might have a role on the action of estrogen.

Objective: The study was conducted to assess the prevalence of subclinical mastitis in dairy cows at Baghabari milk shed area of Sirajganj and Pabna districts in Bangladesh. Materials and methods: A total of 300 milk samples were collected from crossbred dairy cows, and the milk samples were subjected for using California Mastitis Test (CMT). Besides, data related to farm management were taken from 60 farmers through direct interviews. The CMT was compared with White Slide Test (WST) and Surf Field Mastitis Test (SFMT). The samples showing strong positive reaction to mastitis by CMT were used for the isolation of associated bacteria using conventional bacteriological examinations and biochemical properties. The isolated bacteria were subjected for antibiogram studies by disc diffusion method. Results: Out of 300 samples, 153 (51%) revealed positive reactions denoting that the cows were suffering from subclinical mastitis. Of the 153 samples, 39(13%) were trace-positive, 56(18.56%) were weak-positive, 33(11%) were distinct-positive, and the rest 25(8.3%) samples were strongly positive. In comparison economically among CMT, WST and SFMT, SFMT was found to be the cheapest and easiest. In this study, the cows were mostly infected with mixed infection with Staphylococcus spp., Streptococcus spp., Escherichia coli, Salmonella spp., and some cows had single bacterial infection. It was observed that most of the microorganisms were sensitive to Gentamycin, Amoxicillin and Ceftriaxone, and were resistant to Penicillin, Ciprofloxacin and Colistin sulphate. Conclusion: Overall prevalence of subclinical mastitis in the crossbred dairy cows at Sirajganj and Pabna district is 51%. It indicates that subclinical mastitis is a major threat for dairy industry in the studied areas. Early detection and appropriate preventive measures are suggestive to successful control of the disease. [J Adv Vet Anim Res 2017; 4(3.000): 295-300]

Objective: This study was conducted to assess the prevalence of different types of gross testicular disorders in bulls, and to evaluate the associations with sampling year, age, and body condition. Materials and methods: In this study, a total of 398 apparently healthy bulls were randomly selected that were brought from different parts of eastern Ethiopia to the Haramaya University abattoir for slaughtering during the period from June 2014 to September 2016. Ante- and post-mortem examinations of the bulls were employed. Visual inspection, palpation, serial and systematic dissections into the parenchyma of the testes and scrotum were performed to determine the presence and the extent of gross pathological changes. Results: Out of 398 bulls, 209(52.5%) were affected by one or more gross testicular abnormalities of unidentified causes. Bilateral testicular hypoplasia was the most prevalent (9.8%; n=39/398) testicular abnormality, followed by unilateral testicular hypoplasia (9%; n=36/398), testicular hematoma (9%; n=36/398), orchitis (8.3%; n=33/398), testicular degeneration (6.5%; n=26/398), scrotal wound (6.3%; n=25/398) and epididymitis (2.5%; n=10/398). Unilateral cryptorchidism was the least prevalent (1%; n=4/398). Age and body condition did not affect the prevalence of any abnormality (P>0.05) except in scrotal wound which was significantly varied among body condition categories (P<0.05). Conclusion: This study reveals that the incidence of gross testicular abnormalities was 52.5% in bulls. Thus, attention should be given to reproductive management of bulls in Ethiopia.

The roles of wildlife in rabies transmission are still underestimated in many parts of the world. In the developed countries, epidemiology of rabies considering wildlife has been well documented. However, in the least developed and developing countries, emphasis has not given on this issue. Human population is increasing all over the world, and new localities are continuously developing. As a result, wildlife territory is decreasing, and the animals are coming in close contact with humans. Besides, many people are keeping wildlife as the sources of their pleasures. Due to the increased interaction among wildlife, domestic animals and human there is need to intensify efforts on mass education and building of awareness on the risks of rabies spreading by the wildlife, and to institute effective preventive measures to control over the disease. In this mini-review, roles of wildlife in epidemiology of rabies has been discussed considering the dynamics of wildlife in relation with associated intrinsic and extrinsic factors.

Objective: Gastrointestinal (GI) parasitic infection is a prime cause of failures in sheep production. This study was conducted to ascertain the prevalence of gastrointestinal (GIT) helminths of sheep in Sherpur district, Bangladesh. Besides, prevalence of helminthiasis in sheep also assessed considering age, sex, nutritional condition and rearing system. Materials and methods: In total, 106 rectal fecal samples of sheep were randomly collected and were examined for the presence of ova by using direct smear and Stoll&#146;s ova counting techniques during July to October, 2016. Eggs were identified on the basis of its size, morphology and other landmark features. Results: Out of 106 samples, 67.9% (n=72/106) revealed the presence of ova of different helminths. The prevalence of helminth infection was associated with Fasciola gigantica (11.3%; n=12/106), Paramphistomes (13.2%; n=14/106), Schistosoma indicum (3.8%; n=4/106), Moniezia sp. (3.8%; n=4/106), Strongyle-type (24.5%; n=26/106), hook worm (6.6%; n=7/106), Strongyloides sp. (12.3%; n=13/106) and Trichuris sp. (1.9%; n=2/106). Egg count per gram (EPG) was calculated which was ranged between 100 and 600. Parasitic counts in lambs, young and adult showed no significant variations (P=0.511) from one other. Infection was significantly (P=0.04) higher in poor body conditioned sheep (76.3 %) as contrasted to normal body conditioned sheep (57.4%). No significant variation (P=0.601) was noticed in infection rates between sexes. Females displayed a higher infection (70.0%) as compared to males (65.2%). In rearing system, the result was found statistically insignificant (P=0.247). Conclusion: Utterly, GI helminths are endemic at great levels among sheep in the study area. Also, their infestation differs within various age groups, sexes, nutritional condition and rearing system of sheep. [J Adv Vet Anim Res 2017; 4(3.000): 274-280]
