dc.descriptionThe susceptibility of two fish and four mosquito species to the Caiman yacare haemoparasite Hepatozoon caimani was experimentally investigated. Mosquitoes belonging to four species (Aedes fluviatilis, Aedes albopictus, Aedes aegypti and Culex quinquefasciatus) were blood-fed on two naturally infected C. yacare from the Central-West Region of Brazil that exhibited distinct levels of parasitaemia: caimans A (11.05 %) and B (1.25 %). None of the engorged A. fluviatilis, A. albopictus or A. aegypti mosquitoes fed on caiman A survived for the duration of the sporogonic cycle; the great majority of the engorged mosquitoes died within 48 h of the blood meal. All A. aegypti fed on caiman B were negative, whereas 91.3 % of dissected C. quinquefasciatus fed on the same caiman contained oocysts. Characid fish— Metynnis sp. and Astyanax sp.—were individually fed with C. quinquefasciatus females previously engorged (21–23 days) on caiman B. No parasite was found in the Astyanax fish. By contrast, 100 % of the Metynnis fish depicted numerous cysts harbouring cystozoites identical to those of H. caimani, even more than 8 months after the ingestion of the infected mosquitoes. The cysts were located near the veins of the liver and, in some cases, close to the tunica intima of these vessels. No inflammatory reaction was observed. Gametocytes were observed in the blood smears of juvenile caimans that had ingested infected fish 9–12 weeks earlier. The potential role of fish as paratenic vertebrate hosts of H. caimani in nature is discussed.
