Host-parasite specificity in coccidia: infection of the chicken with the turkey coccidium, Eimeria meleagridis

Abstract

1. Chickens were infected with Coccidia, considered to be Eimeria meleagridis, from turkeys. 2. Turkeys were subsequently infected with oocysts obtained from the chickens. 3. Slight variation from normal measurements of the coccidia in chickens is attributed to development in an abnormal host. 4. E. acervulina from chickens was not infective to a coccidia-free turkey chick.
