Abortions in domestic ruminants cause significant economic losses to farmers. Determining the cause of an abortion is important for control efforts, but it can be challenging. All available diagnostic methods in the bacteriology laboratory should be employed in every case due to the many limiting factors (autolysis, lack of history, range of samples) that complicate the investigation process. The purpose of this study was to determine whether the recovery of diagnostically significant isolates from domestic ruminant abortion cases could be increased through the use of a combination of the existing aerobic culture and Brucella selective method with methods that are commonly recommended in the literature reporting abortion investigations. These methods are examination of wet preparations and impression smears stained by the modified Ziehl–Neelsen method, anaerobic, microaerophilic, Leptospira, Mycoplasma and fungal culture. Samples of placenta and aborted foetuses from 135 routine clinical abortion cases of cattle (n = 88), sheep (n = 25) and goats (n = 22) were analysed by the new combination of methods. In 46 cases, bacteria were identified as aetiological agents and in one case a fungus. Isolation of Brucella species increased to 7.4% over two years compared with the previous 10 years (7.3%), as well as Campylobacter jejuni (n = 2) and Rhizopus species (n = 1). Salmonella species (5.9%) and Trueperella pyogenes (4.4%) were also isolated more often. In conclusion, the approach was effective in removing test selection bias in the bacteriology laboratory. The importance of performing an in-depth study on the products of abortion by means of an extensive, combination of conventional culture methods was emphasised by increased isolation of Brucella abortus and isolation of C. jejuni. The combination of methods that yielded the most clinically relevant isolates was aerobic, microaerophilic, Brucella and fungal cultures.

Seroprevalence of Babesia ovis in sheep and goats was studied in Siwa Oasis between January 2002 and January 2003. A total of 240 blood samples were collected from 108 sheep and 132 goats for preparation of blood smears and for separation of serum samples and tested against B. ovis by using IFAT. B. ovis was detected in 55 (50.92%) and 59 (44.69%) blood smears examined in sheep andgoats, respectively. The overall prevalence of B. ovis infection was 71.3% in sheep and 68.2% in goat using IFAT. The seasonal prevalence of B.ovis peaked in both spring and summer as revealed by blood smear examination and IFAT. A total of 143 ticks were collected from 62 sheep and 81 goats during the study. The ticks examined were Rhipicephalus turanicus (75.52%) and Hyalomma anatolicum (24.48%).

In the present study, a total number of 1576 livers of ruminants, including cattle (924), sheep (487) and camels (165) were examined for detection of different pathogenic agents. Among those, a number of 58 cases (3.68 %) were infected with both parasites and bacteria. Out of this number, 3 cases only (0.19 %) were infected with bacterial species (Lactobacillus lactis lactis), 31 cases (1.97 %) were infected with parasitic stages only and a number of 24 cases (1.52 %) were co-infected with both bacteria and parasites. Among the bacterial isolates, 11 genera of bacterial species were found in 27 cases. The obtained results revealed that, all infected cases were cattle. The most prevalent isolate was Enterococcus species which present in 7 cases (25.92 %) among the totally bacterial infected cases, followed by 5 cases showed Staphylococci (18.52 %), then both genus Escherichia and genus Lactobacillus, each was found in 4 cases (14.81 %) and finally 7 genera including;Enterobacter,Micrococcus,Citrobacter,Aerococcus,Pseudomonas,Chrysomonas and Streptococcus; each was found in a single case with a percentage of 3.70 %. Concerning the parasitic affections, it has been found that Fasciola species was the most prevalent type of helminthes present in the infected livers. Among all infected livers, 40 cases (2.54 %) were infected with adult Fasciola gigantica (including 33 cattle and 7 sheep), followed by 8 cases of camels (0.51 %) infected with Hydatid cysts, then 4 cases of sheep (0.25 %) infected with Cysticercus tenuicollis and finally 3 cases of sheep (0.19 %) infected with both Fasciola gigantica and Cysticercus tenuicollis. The results revealed that, a considerable high number of co-infected animals {24 cases (41.38 %) among the totally infected animals} was existed and this reveals that the parasite facilitates the way to the secondary bacterial infection with the end results of hepatic tissue degeneration and necrosis. So, in abattoirs, great attention must be taken for appropriate evaluation of these pathogenic sources.

A total of 165 cows, 19 buffaloes, 192 sheep and 118 goats were examined for detection of Mycoplasma mastitis. The results revealed that 114 (69.59%) and 6 (31.57%) were clinically mastitic cows and buffaloes respectively while 51 (30.9%) and 13 (68.42%) were apparently healthy cows and buffaloes respectively. On examining the apparently healthy cows and buffaloes, 67 (32.84%) and 18 (34.61%) were subclinically mastitic cows and buffaloes respectively. Mycoplasmas were isolated in percentages of 8.9%, 5.5% from subclinically mastitic cows and buffaloes respectively and in percentages of 12.97%, 12.5% from clinically mastitic cows and buffaloes respectively. M. bovis was isolated from 8 (32%) and M. bovigenitalium from 7 (28%) and 10 (40%) unidentified Mycoplasma. Isolation of Mycoplasma from udder tissue in cows and buffaloes were in a percentage of 28.5% in cows while no Mycoplasma isolates were obtained from buffaloes' udder tissues. Application of PCR technique on these isolates and some of the negative samples was positive 100%. On the other hand, the results revealed that 82 of 192 (42.7%) and 43 of 118 (36.44) of the examined sheep and goats respectively were clinically mastitic. Isolation of Mycoplasma was from 11 (13.41%) and 17 (39.53%) of the examined sheep and goat respectively. Identification of these isolates revealed 8 (29%) M. agalactiae isolates and 20 (71%) unidentified Mycoplasma spp. Application of PCR technique on traditionally identified M. agalactiae isolates revealed negative results on using M. agalactiae specific primer while positive results were obtained for the same 8 isolates (100%) on using M. bovis specific primer.

This article reports cases of nitrate poisoning in Indian indigenous cattle breeds comprising two Gir cows aging 4 years each, and one Barugur cow at 1.5 years of age. The cattle with case history of sudden death and oozing of partially clotted blood from the anal opening were brought to the Central University Laboratory (CUL), Center for Animal Health Studies (CAHS), Tamil Nadu Veterinary and Animal Sciences University (TANUVAS) for diagnostic investigation with a suspicion of anthrax. According to anamnesis, all the animals were clinically normal and did not reveal any abnormality on the previous day. The animals were fed with recently harvested sorghum leaves and stalks. Smears examined for anthrax were found negative. Biological test (mice inoculation) for anthrax was also negative. Gross lesions on necropsy examination of the carcases were suggestive of nitrate intoxication. Finally, nitrate intoxication of these cattle was confirmed by chemical and toxicological analysis of fodder, rumen content, aqueous humor, liver, kidney and urine.

Objective: The study was conducted to evaluate economic loss from liver condemnation due to Fasciolosis in slaughtered ruminants in Maiduguri abattoir, Borno State, Nigeria. Materials and methods: Three hundred (300) livers each of cattle, sheep and goats slaughtered were randomly selected and examined for the presence of Fasciola flukes. The infected livers were weighed and economic value in Nigerian Naira (₦) and US Dollar (US$) were assessed. Results: An overall economic loss of ₦602,400.00 (1,882.50 US$) per annum was incurred during the period under study from a total of 753 kg of liver condemned. Total of 428 kg and 325 kg of liver were condemned during dry and rainy seasons respectively, resulting in higher economic loss of (₦342,400.00; 1,070 US$) in dry season and (₦260,000.00; 812.50 US$) during rainy season. More liver were condemned in the adult cattle (372 kg) than in adult sheep (117 kg) and goats (108 kg) during the period of this study. Conclusion: Ruminant fasciolosis is endemic in Maiduguri, and high economic loss for the farmers and butchers are reported in this study. Strengthening and developing better control methods of fasciolosis in ruminants in Borno State is suggested. [J Adv Vet Anim Res 2017; 4(1.000): 65-70]

Objective: The present study aimed to assess for the first time, in Medina, the prevalence of Mycobacterium avium subsp. paratuberculosis in ruminants due to its potential zoonotic importance. Materials and methods: A total of 823 sera samples and 364 milk samples were used to deter¬mine the incidence of Mycobacterium avium subsp. Paratuberculosis (MAP) using the indirect Enzyme-Linked Immunosorbent Assay. Results: The seroprevalence of MAP was 11.1% in sheep and 13.8% in goats, while no infection was recorded among camels. MAP infection was not influenced by the animals gender, but it was influenced by its locality since the infection rate in local animals was higher than that in imported ones with a significant correlation (p < 0.05). MAP infection had a significant correlation (p < 0.05) with 2 years aged animals. On the other hand, the detection of MAP in milk revealed that 17 (13.8%) goats and 12 (4.9%) sheep were infected. The prevalence of MAP in milk samples was not influenced by either the animals age or locality. Conclusion: Sheep and goats may act as a reservoir for MAP to the Medina community. Since Medina is an active area of mass gatherings as a destination for pilgrims throughout the year, therefore, necessary control measures should be implemented to lower the economic losses, zoonotic infections, and the possibility of a global epidemic.

Objective: A retrospective survey was designed to determine the prevalence and factors involved in surgical cases at the Veterinary Teaching Hospital (VTH), Bangladesh Agricultural University from June 2014 to June 2017.Materials and materials: In total, 1042 surgical cases of food animal (large ruminants: n=564, and small ruminants: n=493) and 26 non-food animal (mono-gastric animal) were recorded from patient register book and case recording card. Data were analyzed by Epi Info TM software and frequencies were calculated for different variables using Statistical Package for Social Science (SPSS) software.Result: In large ruminant, hernia (16.13%) ranked top (90% umbilical and 10% lateral) followed by fracture (14.89%), abscess (14.54%), umbilical myasis (10.46%), atresia ani (5.85%) and naval ill (4.07%). Among the reported cattle, 87.41% were crossbred and 12.59% were indigenous. Calf, heifer and adult cattle were 55.32, 10.29 and 34.39% respectively. In small ruminants, castration (32.94%; n=138) ranked top followed by myasis (10.55%) naval ill (10.31%), abscess (7.44%), dystocia (6.24%) and urolithiasis (5.49%). Based on surgical classification in large and small ruminants, 37.56 and 42.50% were reported for general surgery, whereas 28.71 and 7.15% for congenital, 11.18 and 13.12% for gynecological and 2.65 and 37.23 % for andrological problems, respectively. Male and female ratio was 1:1.31 and 2:1 respectively in large and small ruminants, respectively.Conclusion: This study emphasizes the factors related to successful surgical cases management at VTH. The results may help in controlling surgical related cases in Mymensingh region of Bangladesh. [J Adv Vet Anim Res 2018; 5(1.000): 81-87]

Objective: This study was conducted to determine the occurrence of Salmonella in various meat products (beef from cattle, chevon from goats, mutton from sheep and jaziir from camel), by screening the various selling points which includes; meat retailers in abattoir, markets and shops in Maiduguri and its environs. Materials and methods: A total of 120 samples of fresh meat from cattle, sheep, goats and camels sampled from ten meat retailers in abattoir, markets and shops in the Maiduguri metropolis, using simple random sampling technique. All samples were processed and examined according to standard bacteriological protocols. Results: Percentage occurrence of Salmonella species had the highest value of 15 (50.1%) from the market, found in sheep, while the lowest occurrence of Salmonella species was associated with 3(10.0%) in goats sampled from shop meat.. Antibiotic susceptibility pattern of Salmonella species from cattle meat revealed high resistant to Erythromycin (52%). In sheep, the higher percentage of resistance occurred against Ampicillin (33.3%) and less resistant to Amoxicillin (4%) was obtained. The isolates from camel meat recorded 25% resistant against Ampicillin, Gentamycin and 12.5% to Streptomycin. A total of 28.4% of the isolates were resistant to Ampicillin, Gentamycin and 23.1% to Ofloxacin. Conclusion: The study has shown that Salmonella species are present in fresh meat sold in abattoir, retail markets and shops. We recommend strict hygienic measures in places where fresh meat are sold in Maiduguri metropolis, Nigeria to ensure consumers right to have safe food. [J Adv Vet Anim Res 2017; 4(3.000): 227-233]

Objective: The objectives of this study was to investigate phenotypically the prevalence of Staphylococcus aureus and Methicillin Resistance S. aureus (MRSA) in ruminants and animal handlers in Maiduguri, Nigeria. Materials and methods: A total of 937 samples (900 nasal and skin swabs of cattle and 37 humans samples) were collected in Maiduguri metropolis. The samples were inoculated onto mannitol salt agar (MSA) and blood agar, and the cultrue plates were incubated at 37oC for 24 h. The S. aureus colonies showing golden yellow color on MSA were primarily identified as S. aureus, which were then subjected for catalase and coagulase tests. All S. aureus were finally screened for the presence of MRSA on oxalate resistant screening agar (ORSAB) medium. Antimicrobial susceptibility of the MRSA were measured by disc diffusion method. Results: The overall prevalence of S. aureus was 44.3% (n=414/937). The MRSA could be detected in 12.1% (n=113/937) samples. Considerign different species, S. aureus could be isolated from 137 (45.6%), 148 (49.3%) and 119 (39.7%), 11 (29.7%) cattle, sheep, goat and humans, respectively. In ruminants, 27.7% (n-83/300) bulls were positive for S. aureus. Similarly, 10.7% (n=32/300) and 22.3% (n=67/300) were positive for S. aureus in rams and bucks, respectively. On the other hand, 18% (n=54/300), 38.7% (n=116/300) and 17.3% (n=52/300) samples from cows, ewes and does were positive for S. aureus. The highest MRSA could be isolated from ewes (9.3%; n=28/300) follwed by bulls (7%; n=21/300) and bucks (6.7%; n=20/300). In humans, 13.5% (n=5/37) samples were positive for MRSA.Conclusion: S. aureus and MRSA infections in ruminants and animal handlers are documented in this study. The MRSA may exert public health threat to humans. [J Adv Vet Anim Res 2016; 3(2.000): 152-159]
