Abstract
The life cycle and pathogenicity are described of a pure strain of Eimeria isolated from turkey poults in Great Britain and identified as E. meleagrimitis.There were three schizogony cycles followed by a sexual generation.The coccidium produced a high mortality and loss of weight in young poults.An age resistance developed by the time the poults were 8–10 weeks of age.The pathology of the infection is described.
