Abstract

A total number of 151 sheep are examined by the routine meat inspection. It is found that the total prevalence of metacestodes infecting sheep carcasses was 31.79%. Four types of metacestodes are detected; Cysticercus ovis, Cysticercus tenuicollis, Coenurus cerebralis and Hydatid cyst. Prevalence of the revealed parasites are estimated, where the prevalence of C. ovis was 11.26%, Hydatid cyst (0.66%), C. tenuicollis (19.21%) and C. cerebralis (7.28%). Concerning the seasonal dynamics of the revealed parasites, autumn season was the highest season for infection with C. tenuicollis (28.95%), and winter in case of hydatidosis (2.44%), while C.ovis reached its maximum during summer (17.14%). Moreover, spring season was the highest for infection with C. cerebralis (10.81%). Heart was the most predilection site for C. ovis infection (82.35%) and omentum for C. tenuicollis (65.52%). Hydatid cyst is only recovered from liver and C. cerebralis only detected in brain. Dealing with the prevalence of the revealed parasites in different ages, Hydatid cyst was only detected in aged animals and C. ovis in sheep 1-2 years old, while C. cerebralis and C. tenuicollis are revealed from sheep over two years of age. Microscopical examination of the obtained parasites was performed for identification.
