Sero-Prevalence of Bovine Foot and Mouth Disease in Selected Districts of Eastern Showa Zone, Oromia Regional State, Ethiopia.
A cross-sectional study was conducted from September 2014 to July 2015 with the objective of determining sero-prevalence of Foot and Mouth Disease (FMD) in cattle in selected districts of Eastern Showa Zone, Oromia Regional. Blood samples were collected from a total of 634 cattle at Export abattoir, Veterinary Clinics in and around Bishoftu town of Adaa district and Bull screening quarantine station in Adama. The study animals were selected by systematic random sampling and blood samples were collected from jugular vein using sterile vacutainer tube. The blood samples were submitted to the National Veterinary Institute (NVI), and the serum were harvested and processed by using 3ABC-ELISA technique. The current study indicated the overall sero-prevalence of bovine FMD was 10.88% and statistically there were differences (P=0.002) in sero positivity of FMD among animals from Abattoir, Veterinary clinic and Feedlot. The sero-prevalence was higher in animals tested from export abattoirs than those from Feedlot and Clinics.
Prevalence, Isolation of Bacteria and Risk Factors of Mastitis of Dairy Cattle in Selected Zones of Oromia Regional States, Ethiopia
A cross sectional study was conducted on a total of 471 cross and pure borana breed dairy cattle to determine prevalence of clinical and subclinical mastitis using CMT in selected districts of North Showa and Borana zones of pastoral area from April 2012 to February 2014. The overall mastitis prevalence was 237(50.3%). The cow level prevalence was 9.5% clinical and 40.7% were subclinical cases. Of 1884 quarters examined 10(0.5%) quarters were blind teats and quarters 550(50.2%) were showed mastitis. High score CMT positive milk sample were investigated using standard microbiological techniques. Identification of bacterial isolates revealed that 10 types of bacterial isolates were identified. The isolated bacteria were Staphylococcus aureus and CNS 20 (37.7%), Diplococcus spp 2 (3.8%), Corynebacterium pseudotuberclosis 3(5.8%), Corynebacterium bovis 1(1.7%), Micrococcus spp 1(1.9%), Pseudomonas spp 1(1.9%), Bacillus spp 1(1.9%), E. coli 3(5.7%) Proteus spp 1(1.9%). Different risk factors like parity number, farming hygiene, animal origin and husbandry type were considered. Hygienic conditions and husbandry type were the most important potential risk for mastitis.
