Bovine Hydatidosis in Eastern Part of Ethiopia
Abstract
A cross-sectional study was conducted on bovine hydatidosis from November 2010 to March 2011 with the aims of investigating its occurrence, risk factors and economic losses in Dire Dawa municipality abattoir. The study revealed 20.05% occurrence of hydatidosis based on the postmortem examination of1536 cattle. Age related infection was significant as older animals were more infected (P<0.05, x2 = 27.496).Among the lungs, liver, heart, spleen and kidneys examined in each carcass, the cysts were distributed in the lungs and livers only. Out of 1852 cysts, 1340 (72.3%) were found in liver while512 (27.7%) in lungs. Five hundred and twenty (53.94%) of 964 hydatid cysts were small, while268 (27.80%) medium and 176 (18.25%) large. These cysts were further characterized as fertile (80.08.7%), sterile (17.3%) and calcified (2.85%) and 53.7% of fertile cysts were viable. Based on the study, the direct economic loss was estimated to be 23,876 Ethiopian Birrs. Presence of hydatid cysts in edible organs has great public health significance as consumption of undercooked/raw meat is still in practice in many parts of Ethiopia.
