Feces from 184 sheep from Dakahlia governorate, Egypt were tested for Eimeria species oocysts by using the standard floatation technique; oocysts were detected in 126 (68.4%). The prevalence was significantly higher in young sheep than adults. Eleven Eimeria species were identified: Eimeria ahsata, Eimeria bakuensis, Eimeria crandallis, Eimeria faurei, Eimeria granulosa, Eimeria intricata, Eimeria marsica, Eimeria ovinoidalis, Eimeria pallida, Eimeria parva and Eimeria webybridgensis. Oocysts of the most pathogenic ovine species, E. ovinoidalis, were detected in 27 (14.6%) sheep. This is the first report of E. webybridgensis in sheep from Egypt, possibly due to close similarity of their oocysts to those of E. crandallis which stated in the earlier reports. Worldwide reports on epidemiology of Eimeria spp. infections in sheep are tabulated. |
