Entamoeba bovis liebetanz 1905 recorded from large ruminants in Egypt

ABSTRACT

Investigations carried out on trematode parasites affecting cattle and buffalos in Ismailia Governorate revealed a degree of infection with Fasciola sp. attaining 6.95% among the former, and 16.16% among the latter. Concerning Paramphistomum sp. infection, it was 43.83% among cattle and 9% among buffalos. During these studies, it appeared that cattle or buffalos having no infection with Fasciola sp. or those being infected with Paramphistomum sp. only proved to harbor Entamoeba bovis trophozoites with a percentage of about 85% in cattle, and 80% among buffalos. This protozoan parasite was also recovered from the gallbladders and bile ducts of slaughtered beef cattle that had no infection with liver flukes. The morphological picture of the fresh E. bovis trophozoite as well as its cyst were described, and the significance of such parasite on its host was discussed
