STUDY ON PREVALENCE AND CYST CHARACTERIZATION OF HYDATIDOSIS IN CATTLE SLAUGHTERED AT WOLAYTA SODDO MUNICIPAL ABBATTIOR

Abstract

A cross-sectional survey of bovine hydatidosis was conducted on local zebu cattle slaughtered at Wolayta Soddo Municipal Abattoir from November, 2012 to March, 2013 to determine the prevalence and cyst characterization caused by hydatid disease. No statistical significant variation was observed with regards to place of origin and age of the animals (P > 0.05). After postmortem examination, hydatid cysts were collected and cyst characterization was conducted. Out of a total of 446 animals examined, 50(11.21%) harboring one or more hydatid cyst. The result obtained from Postmortem examination indicated that the lung was the most commonly affected organ followed by liver. The involvement of lung, Liver, kidney, spleen and heart was found to be 50%, 26.92%, 5.77%, 9.62% and 7.69% respectively. From the total of 52 cysts counted, 14(26.69%), 18(34.62%), 20(38.46%) were large, medium and small respectively and 5(9.62%), 35(67.31%) and 12(23.08%) were fertile, sterile and calcified respectively. Out 5 of fertile, 20% (1/5) were viable, all from the lung and higher liver calcification were observed.
