Abstract

Eimeria tenella-specific antibodies were examined for the cross-reactivity on the sporozoites and merozoites of E. tenella, Eimeria maxima, Eimeria acervulina and Eimeria brunetti in an indirect fluorescence antibody test. Two of nine antibodies showed cross-reactivity with sporozoites of E. maxima, E. acervulina and E. brunetti; however, the localization of specific fluorescence differed between species. No antibody binding was observed on merozoites. The suitability of these antibodies to alter the infectivity of Eimeria sporozoites and/or merozoites must be verified in cell culture models and in vivo experimental infections.
