The coccidia of sheep and goats in Senegal.

A survey of the coccidia in domestic sheep and goats was undertaken to ascertain the type of Eimeria species and the number of different coccidial species in individual faecal samples. Simultaneously the prevalence and the oocyst output was investigated in 2234 sheep and 577 goats during a 12-month period. Eight Eimeria species were encountered in sheep: E. ahsata, E. crandallis, E. faurei, E. intricata, E. ovina, E. ovinoidalis, E. pallidas and E. parva. In goats the following species were found: E. ahsata, E. arloingi, E. christenseni, E. crandallis, E. faurei, E. intricata, E. ninakohlyakimovae and E. parva. The prevalence in sheep ws 94% and in goats 85%, multiple parasitism was the rule. No seasonal fluctuation was observed in the prevalence or oocyst output. The sheep and goats' oocyst output was moderate, the mean for both being in the range of 1000-5000 oocysts/g of faeces.
