PROTOZOOLOGICA A Sarcocystis Species from Goshawk (Accipiter gentilis) with Great Tit (Parus major) as Intermediate Host

Summary. Dne hundred and seventy five passerine birds from the Czech Republic were examined for the presence of sarcosporidia; auly 5 (all great tits) were positive for muscle cysts. Three great tits experimentally fed sporocysts (12.2 x 8.4, 11-13x 7.5-9!lm) from a goshawk developed cysts while 2 h...

Three great tits experimentally fed sporocysts (12.2 x 8.4, 11-13x 7.5-9!lm) from a goshawk developed cysts while 2 house sparrows (Passer domesticus) were not infected. The cysts from great tits muscles were morphological1ysimilar to thosefoundin naturalinfections.The thin-walledcysts containedbanana-shapedcystozoites6.9 x 1.8(5.9-8.5x 1.3-2.3)!lmin size.The natural life cycle of this Sarcocystis species involves goshawks and great tits. The relation of this species to S. accipitris is discussed.
