The nematode, Haemonchus contortus, is responsible for major economic losses in the livestock industry. The management of parasites such as H. contortus has been through the use of synthetic parasiticides. This has resulted in the presence of residues in meat and milk, which affects food safety. The development of resistance to available anthelmintics coupled with their high cost has further complicated matters. This has led to the investigation of alternative methods to manage nematodes, including the use of plants and plant extracts as a potential source of novel anthelmintics. Acetone extracts were prepared from 15 South African plant species and their anthelmintic activity determined using the egg hatch assay (EHA). The leaf extract of Cleome gynandra had the best inhibitory activity (68% ± 3%) at a concentration of 2.5 mg/mL, followed by the stem extract of Maerua angolensis (65% ± 5%). The extracts had a relatively low toxicity on Vero cells determined by the MTT (3-(4,5-dimethylthiazol-2-yl)-2,5- diphenyltetrazolium bromide) cellular assay.

Objectives: Bovine anaplasmosis is an arthropod-borne hemolytic disease of cattle  which  is caused by a rickettsia; Anaplasma marginale. Anaplasmosis is also called "Yellow bag" or yellow fever, where the affected animals usually develop a jaundiced appearance. The objective of this study was to investigate the clinical findings, treatment and gross pathology of a severe anaplasmosis in a dairy cow.  Materials and methods: In this report, a rare case of fatal anaplasmosis in a 4 year old Jersey-Friesian cow, weighing about 200 kg was reported. Diagnosis was done based on clinical symptoms, blood examination for the presence of A. marginale, and biochemical analyses of blood. Leishman staining was done to check the A. marginale at the margin of erythrocytes. Treatment was instituted with blood transfusion and Oxytetracyline dosed at 20 mg/kg body weight and iron supplement containing 20 mL Cobaphos (containing Phosphorus 125mg + Cyanocobalamine 0.05 mg) and 20 mL Fercobsang containing Iron (as ammonium citrate) 1.75 mg, Cyanocobalamine (Vitamin B12) 0.025 mg, Nicotinamide (vitamin PP) 20 mg, Cobalt (as digluconate) 0.0067 mg, Benzyl Alcohol (E1519) 20.8 mg) were given intramuscularly.Results: The cow did not survive the infection as it eventually died of the disease. Post mortem examination showed gross evidence of splenomegaly, hepatomegaly, distended bile duct and generalized jaundice.Conclusion: Based on the consequence of this case report, preventive vector control,  prompt and appropriate treatment and improved management practices are recommended in order to prevent clinical anaplasmosis cases among cattle.http://doi.org/10.5455/javar.2016.c150

Objective: This case report describes the management of a clinical case of trypanosomosis in an adult Friesian Sahiwal cow.Materials and methods: An adult cow aging 3 years was presented with a complain of wound infection, weakness and inappetence. Physical examination was carried out and samples were collected for laboratory investigations.Results: The clinical history revealed generalised enlargements of the pre-scapular and pre-femoral lymph nodes, pale mucous membrane and weight loss. Laboratory investigation showed that the cow had normocytic normochromic anemia with hyperproteinemia. Thin blood smear examination revealed the presence of Trypanosoma evansi. Treatment was instituted with Diminazene aceturate dosed at 3.5 mg/kg bwt through intramuscular (IM) route for 3 days, 20 mL of Fercobsang for 3 days, IM, Flunixin meglumine dosed at 1.1 mg/kg bwt, IM, and Oxytetracycline dosed at 20 mg/kg bwt, IM once. The wounds were cleaned daily for one week. Examination of the blood film after therapy showed no parasite.Conclusion: The findings of this case report demonstrate the importance of an effective treatment regimen in managing bovine trypanosomosis in an endemic farm.http://doi.org/10.5455/javar.2016.c164

Objectives: This study was designed to assess the contamination of enterovirulent Escherichia coli with table eggs at Mansoura, Egypt.   Materials and methods: A total of 100 commercially available table eggs were randomly collected from various groceries and supermarkets at Mansoura, Egypt. The samples were screened for the presence of E. coli through conventional bacteriological and biochemical analyses followed by confirmation by polymerase chain reaction. Results: Overall, 18% (n=18/100) samples were found to be contaminated with one or more E. coli isolates. All possible E. coli colonies (n=52) appeared on MacConkey agar plates during the screening process were picked for further analysis. Among the 52 suspected isolates, 24 were confirmed as E. coli, which were further serotyped using polyvalent E. coli antisera. In this study, 9 different E. coli serotypes namely O78, O114, O2, O44, O1, O125, O128, O124 and O26 were identified. Out of these 9 serological strains, 5 (O78, O2, O44, O125, O124 and O26) were positive for eae gene, and 3 (O44, O1 and O128) were positive for stx2 gene. Two serological strains (O44 and O1) were positive for both stx1 and eae genes, while O125 and O114 were positive for stx2 and eae genes. Two strains (O78 and O128) were found to be positive for all three genes (stx1, stx2 and eae). Conclusion: Ensuring hygienic measures can effectively reduce the microbial load from table eggs.http://dx.doi.org/10.5455/javar.2016.c123

Objectives: Here we determined the prevalence of Salmonella in cloacal swabs and pharyngeal swabs of apparently healthy pigeons sold in the live bird markets and villages in and around Bangladesh Agricultural University Campus, Mymensingh, Bangladesh. Materials and methods: A total of 50 samples, comprised of cloacal swabs (n=24) and pharyngeal swabs (n=26) were collected. The samples were processed, and Salmonella was isolated through a series of conventional bacteriological techniques and biochemical tests followed by polymerase chain reaction (PCR). Results: The prevalence rate of Salmonella was found to be 37.5% (n=9/24) in cloacal swabs and 30.77% (n=8/26) in pharyngeal swabs with an overall prevalence rate of 34% (n=17/50). The prevalence rate of Salmonella pigeon varied slightly among locations; 34.62% (n=9/26) in live bird markets, and 33.33% (n=8/24) in villages. Molecular detection of 17 Salmonella isolates obtained from biochemical test was performed by genus specific PCR, where all of them amplified a region of 496-bp segment of the histidine transport operon gene. Antibiogram study revealed multi-drug resistant traits in most of the isolates tested. The highest resistance was found against Ampicillin (88.23%) followed by Cephalexin (82.35%). The rate of sensitivity of the isolates to Ciprofloxacin was 100% followed by Azithromycin (82.35%), Gentamicin (76.47%) and Nalidixic acid (76.47%). Conclusion: Our findings suggest that pigeons carry multi-drug resistant Salmonella that may transfer to the humans and animals.http://dx.doi.org/10.5455/javar.2016.c131

Objectives: This study was designed to investigate the Sero-prevalence of Schistosoma species in cattle in Maiduguri Metropolis (MMC) and Jere Local Government Areas (LGAs) of Borno State, Nigeria. Materials and Method: Blood samples (n=200) from cattle were collected using a multistage sampling technique; 100 samples each were collected from MMC and Jere LGAs, respectively. The samples were subjected to screening for Schistosoma antibodies using Enzyme Linked Immunosorbent Assay (ELISA). Age, sex, breed and location of cattle were recorded. Results: The overall prevalence of Schistosoma infection among cattle in MMC and Jere LGAs was 10%. Jere LGA had a prevalence rate of 14% and MMC had 6%. At the ward levels, Custom Area in Jere LGA had the highest number of Schistosoma positive (50%). Out of 103 female and 97 male cattle screened, the prevalence of Schistosoma infection in female and male were 9.71% (n=10/103) and 10.31% (n=10/103). Out of the 177 serum samples from cattle aging &gt;1-year (adult) examined, 16 (9.04%) were positive, while only 4 (17.39%) out of 23 serum samples from cattle aging &lt;1-year (young) were positive. Out of the eight (8) breeds screened, the highest number of cases was recorded in Kuri breed (16.22%). This was followed by Sokoto Gudali (10.9%) breed. The prevalence in other breeds was as follows: Abore- 10%, Red Bororo- 5.26%, and White Fulani- 6.67%.  Conclusion: It is concluded that schistosomiasis in cattle was prevalent in MMC and Jere LGAs of Borno State. A regular checking program is suggested to constantly check out whether the prevalence rate is increasing, so that effective control measures can be strenthened. http://dx.doi.org/10.5455/javar.2016.c132
