ABSTRACT
Coccidiosis of chickens, caused by species of Eimeria (Protozoa, Apicomplexa), is an intestinal disease of major economic
importance worldwide. In the present study, the reproductive characteristics of a precocious line (designated E. tenella Rt3+15)
from Australia were investigated in chicken embryos and the implications of the findings briefly discussed.
