ABSTRACT The existence oj tissue parasites among slaughtered animals tuns studied in 5 abattoirs in Dokahlfa Province namely Mansoura. Bclql,l:(l.S, SenbeUawlf1e, lJekemes and Sherbeene. A total number oj 2048 eatiCe, 648 buffalO€s and 133 sheep were ex amined during the perWd extended Jrom September 2005 (ttl the end oj August 2006. The overall tiSsue paraslles prevalence was 18.2 % in large rumlnants and 22.56 % in small rwnlnants. Five tL<;sue parasites were detected named C. boviS, Hydatid cyst. C. tenufco!!i5. C. ouis and Sarcocystis spp. Examination oj catUe carcasses revealed C. bo t..'is (",61%) and Hydatid. cyst (0.15%). Also. Hydatid cysts were detected in 0.15% oj e.xa.mlned buffalos. Morecwer buffalo carCasseS investigation reuealed Sarcocystis spp. cysts (63.7%). SmaU rwninant represented by sheep revealed C. ovis (8.27%) and C. tenuJcoWs (14.2mb).
