Development of Leucocytozoon caulleryi in chick embryos infected by biting of Culicoides arakawae through shell membrane.
Chick embryos were infected with Leucocytozoon caulleryi by biting of the midge, Culicoides arakawae, through the shell membrane. Schizonts of L. caulleryi were detected in the chorioallantoic membrane and most of the internal organs of embryos and of chicks after hatching. The development of schizonts was slower in embryos than in chickens. Soluble antigens of L. caulleryi were demonstrated by the precipitation test in the allantoic fluid and blood from the embryos and chicks. No erythrocytic stage of L. caulleryi, however, was observed in any embryo or chick.
