The occurrence of Eimeria marsica in the domestic sheep in England and Wales

Abstract
Eimeria marsica Restani 1971 is re-described from oocysts recovered in pure culture from experimentally infected coccidia-free lambs. The ellipsoidal oocysts, which measure 19·1 x 131 μm, possess an inconspicuous micropylar cap. The prepatent period varies from 14–16 days. E. marsica is recorded for the first time from sheep in England.
