title: Extraintestinal sporozoites of chicken Eimeria in chickens and turkeys.
abstract: Oocysts were found in the feces of chickens (recipients) dosed orally with whole blood, liver, lung, or heart homogenates from chickens and turkeys (donors) inoculated 3 and 4 days previously with a mixture of 3.5 X 10(6) oocysts of chicken Eimeria. No oocysts were found in the feces of recipients given spleen homogenates from these same chickens and turkeys and none were found in the feces of recipients given similar material from uninoculated donors. Intracellular sporazoites were found in the peripheral blood of a turkey inoculated with chicken Eimeria. The results indicate that a small number of sporozoites are capable of invading and surviving for at least 4 days in the peripheral blood of chickens and turkeys.
