Title of thesis: Studies on some parasitic infestation in slaughtered animals in upper   Egypt

ABSTRACT

Our study was carried out in year 2007, to show the prevalence of some parasitic infestation among cattle, buffaloes, camels, sheep and goats slaughtered in Qena, Sohag and Aswan. The highest rate of Fasciola spp. was seen in sheep (5.9%), followed by goats (4.87%), buffaloes (4.7%) and cattle (3.8%), but not recorded in camels. Cysticercus bovis was (1.4%) in cattle and (0.58%) in buffaloes. Cysticercus ovis was (0.32%) in sheep.  Hydatid cyst was (12%) in camels, (2.43%) in goats and (0.56%) in sheep, not found in cattle and buffaloes. Cysticercus teniucollis was (17%) in goats and (13.1%) in sheep. Female and adult animals were more susceptible for parasitic infestation than male and younger animals. The highest seasonal prevalence of Fasciola spp. was in winter, Cysticercus bovis and Cysticercus ovis were in spring while Hydatid cyst and Cysticercus tenuincollis were in autumn. Heart, masseter muscle, tongue and gluteal muscle were the most predilection seats of Cysticercus bovis. Heart was the only predilection seats of Cysticercus ovis.  Hydatid cyst in camels were found in lungs more than livers and vice versa in sheep. Mixed infection of both lungs and livers was found in camel but in sheep it is not found. Cysts of Cysticercus tenuincollis tend to be located in the omentum other than any other organs.
