Entamoeba bovis liebetanz 1905 recorded from large ruminants in Egypt

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

Experimental transmission of some blood parasites rhipicephalus species in Egypt II the role of R turanicus in transmitting babesia ovis in sheep

Studies on experimental transmission of Babesia ovis were undertaken using laboratory bred Rhipicephalus turanicus, together with splenectomized and non-splenectomized sheep. Vermiform merozoites were detected in haemolymph of engorged female ticks as well as in some eggs of the 4th batch. On the other hand, stage-to-stage transmission of B. ovis by R. turanicus failed

Experimental transmission of some blood parasites by phipicephalus species in Egypt I the role of R turanicus in transmitting theileria species in sheep

Studies on experimental transmission of theileriosis to sheep were undertaken using laboratory bred Rhipicephalus turanicus and 3 splenectomized rams. Stage-to-stage transmission of the parasite was also studied. Blood film examination, clinical observation and regional lymph gland biopsy through a period of 30 days failed to demonstrate successful transmission of the protozoon
