The development of Hepatozoon sipedon sp. Nov. in its natural host, the Northern water snake, in the culicine vectors Culex pipiens and C. Territans, and in an intermediate host, the Northern leopard frog

The life cycle of Hepatozoon sipedon sp. nov. was studied in two snake species, the Northern water snake and the Eastern garter snake, in its mosquito hosts Culex pipiens and C. territans, and in the Northern leopard frog. Gametogenesis, fertilization and sporogony occurred within fat body cells in the haemocoel of mosquitoes that had fed on infected water snakes.
