ABSTRACT
Parasitic infections among slaughtered pigs in El—Basateen abbatoir in, Cairo have been studied. 40634 slaughtered pigs during the period from June 1988 to June 1989 were examined for trichinosis and cysticercosis, Recorded prevalence of trichinosis as measured by direct muscle examination and cysticercosis as measured by nacked eye examination for cysticercus cellulose detection were 2.33 % and 0.08% respectively, with no significant change when compared with the mean prevalences of trichinosis and cysticercosis in the preceeding five years, recorded in the same abbatoir. The prevalence of Toxoplasma infection was 14% through examination of sera of 100 slaughtered pigs by the indirect haemagglutination test (IHAT). The prevalence of Balantidiurn coli infection was 81% through examination of 200 slaughtered pigs by simple smear method for stool examination.
