Eimeria ahsata Honess from domestic sheep (ovis aries) in Italy

Prevalence of Eimeria species in sheep (Ovis aries) from Dakahlia governorate, Egypt

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.

Epizootiology of Eimeria ahsata coccidiosis in León (Spain)

The epizootiology of ovine coccidiosis caused by Eimeria ahsata was studied in four flocks in the province of León (Spain), between January 1978 and December 1979. The intensity of infection was found to be 25.5 +/- 1.7% and was similar in winter and spring. Eimeria ahsata was the most common species in 83.1% of the 1620 samples examined. It was also found in 86.2% of the animals examined. Only 0.3% of the positive samples contained oocysts of a single species, and samples containing four species were the most frequent (19%). Twenty-three percent of samples contained five species and 31.3% contained six species.
