Amira Hussein El-Baz | Mohammed El-Sherbini | Adel Abdelkhalek | Maha Abdou Al-Ashmawy
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.

Tamour Elkhier | Shams-Eldein Hassaballa | Shadia Abdo-Elatti Omer | Abdelnasir Adam
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 µg/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˂0.05) increased as a result of 80 µg EB injection, while significantly (P˂0.05) decreased due to 40 and 120 µg EB injection. Total protein significantly (P˂0.05) increased due to injection of 40 µg EB, however t-protein was not changed due to 40 and 120 µg injection. On the other hand, the results of albumin and calcium were not affected (P˃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]

Amare Eshetu Gemeda
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.

Julius Olaniyi Aiyedun | Oladapo Oyedeji Oludairo | Isaac Dayo Olorunshola
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’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]

Objective: Foot rot is one of the most important causes of lameness and economic losses in sheep and goats world-wide. This case report described the clinical management of lameness due to foot rot in two female Boer goats aging 4-year both from two different farms in Selangor, Malaysia. Materials and methods: The goats were presented with the complaint of non-weight bearing lameness of the right forelimbs. The hoof was broken and the interdigital space was filled with dirt and exuding a foul smelling odor. Results: On clinical examination, the goats were looking as dull and isolated with body condition scores of 2.5/5 (case 1) and 3/5 (case 2), respectively. The goats had a rectal temperature of 38.8°C and 40.4°C, pulse rate of 80 and 100 beats per minutes, and respiratory rate of 44 and 24 cycles per minute, respectively. Blood sample was collected for complete blood count and serum biochemistry from case 1 only. The hoof was thoroughly washed and disinfected. Parenteral administrations of Flunixin meglumine (dosed at 2.2 mg/kg bwt, IM) thrice daily and Oxytetracycline (dosed at 20 mg/kg bwt, IM case 1) once and Sulfadiazine+trimethoprim (dosed at 1 mL/16 kg bwt, IM case 2) for 3 days. Topical oxytetracycline was applied to the area for 5 days. Conclusion: The prognosis was very good as there was a significant improvement in the hoof injury of both animals. The goats were recovered after 7 days of treatment. [J Adv Vet Anim Res 2017; 4(1.000): 110-116]

Objective: This study envisages dynamics and factors affecting fecal oocyst counts (FOC) in natural infection in goats in semi-arid India. Materials and methods: A total of 1152 fecal samples from Jamunapari goats in semi-arid India were collected, processed and examined for fecal oocysts over a period of 3 years for prevalence and severity of the disease through FOC using modified Mc Master Technique. The log transformed FOC data on 912 animals from 59 sires were used for subsequent analyses for genetic and non-genetic factors affecting FOC. Fixed effects included were years of collection (1-3), seasons of collection (summer, rainy, winter), sex (male, female), age group (0-3, >3-6, >6-12, adults). Least squares analysis of variance for fitting constant was applied to data set. Results: The overall prevalence of coccidian infection in goats was 86.71%(n=999/1162). Highest incident was found in winter season (91.74%) and >6-12 M age (97.95%). Eimeria arloingi and E. ninakohlyakimovae were the most frequently occurring species. The heritability of FOC was found to be 0.06±0.06. The effect of sire on FOC was not significant; however, effects of animal age, year, season of collection and sex on FOC were found to be significant. Conclusion: Coccidiosis in goats is seasonally occurring disease, most commonly affecting animals of less than one year age. FOC in coccidiosis affected animals is lowly inherited trait for selection of goat against this disease. [J Adv Vet Anim Res 2017; 4(1.000): 52-57]

Objective: We aimed at determining the prevalence and characterizing the CaPV, determining the CaPV-PPRV coinfection prevalence and providing data about phylogenetic relationship between the fusion protein of PPRV and P32 gene of CaPV. Materials and methods: A total of 150 samples including animals swabs, tissues and blood were collected from unvaccinated goats in a PPR and/or Capripox outbreaks in South Kivu, Eastern of Democratic Republic of the Congo. Conventional PCR and reverse transcriptase (RT-PCR) were used respectively to amplify P32, RPO30, GPCR genes of Capripox virus and Fusion (F) protein of PPRV. Positive samples were sequenced for phylogenetic analysis. Results: Out of 150 tested animals, 64.7% (n=97/150) were PPRV positive, 52.7% (n=79/150) were Capripox positive and 38.7% (n=58/150) were positive for both PPRV and CaPV. The pairwise comparison of P32 gene of CaPV and F gene of PPRV showed 99.75% of identity percentage among goatpox virus sequences, 96.95% among PPRV sequences and 47.91% between CaPV and PPRV sequences. Conclusion: The study has demonstrated high prevalence of CaP V-PPRV mixed infection in South Kivu. Lumpy skin virus disease (LSVD) is a lineage circulating which has a genetic relationship between its P32 gene and the F gene of PPRV giving the challenge to differentiate the two diseases at the clinical farm level.
