Prevalence of Bovine Hydatidosis in Cattle Slaughtered at Nekemte Municipal Abattoir Western, Ethiopia

Abstract

Across-sectional study was performed at the Nekemte municipal abattoir, Western Ethiopia from October 2016 to August 2017 with the aims of finding to determine the prevalence of bovine hydatid cyst, assess the related risk factors and evaluate organ level of distributions of the cysts.. An ante mortem and postmortem examination was performed as usual on all 220 chosen slaughtered cattle. The organs of systemically selected cattle were evaluated by visual inspection and palpation. Of the total number inspected 44 (20%) had one or more hydatid cysts in one or more of their organs harbored hydatid cysts. Both age and sex of the cattle were significantly associated with the prevalence of bovine hydatidosis (X2=5.928: P=0.015 and X2=4.086: P=0.043, respectively) among the risk factors evaluated. 44(20.%) of the 220 animals evaluated were positive for hydatidosis. In terms of organ distribution, the liver accounted for 27(61.4%), the lung for 16 (36.3%), and the spleen for 1(2.3%).34(55.8%) of the 62 cysts counted and characterized were found in the liver, 27(53.6%) in the lung, and 1(2.3%) in the spleen.22 (35.5%) of the 62 cysts collected were calcified, and 31 (50%) were found to be fertile. Of 7(22.6%) of the 31 fertile cysts were discovered in the liver,23(74.2%) in the lung, and 1(2.3%) in the spleen. Hydatidosis is still one of the most critical diseases that need to be given careful consideration for prevention and control measures in the East Wollega zone, even with the moderate level of infection currently detected. This is because there appears to be a socioeconomic environment that is conducive for the disease. Therefore, the installation of regulated, well-equipped abattoirs, public awareness campaigns, and stray dog control are crucial.
