 en Haematozoan Parasites of the Lizard Ameiva ameiva check for this species in other resources (Teiidae) from Amazonian Brazil: a Preliminary Note
Ralph Lainson; Manoel C de Souza & Constância M Franco

Abstract

Three different haematozoan parasites are described in the blood of the teiid lizard Ameiva ameiva check for this species in other resources Linn. from North Brazil: one in the monocytes and the other two in erythrocytes. The leucocytic parasite is probably a species of Lainsonia check for this species in other resources Landau, 1973 (Lankesterellidae) as suggested by the presence of sporogonic stages in the internal organs, morphology of the blood forms (sporozoites), and their survival and accumulation in macrophages of the liver. One of the erythrocytic parasites produces encapsulated, stain-resistant forms in the peripheral blood, very similar to gametocytes of Hemolivia check for this species in other resources Petit et al., 1990. The other is morphologically very different and characteristically adheres to the host-cell nucleus. None of the parasites underwent development in the mosquitoes Culex quinquefasciatus check for this species in other resources and Aedes aegypti check for this species in other resources and their behaviour in other haematophagous hosts is under investigation. Mixed infections of the parasites commonly occur and this often creates difficulties in relating the tissue stages in the internal organs to the forms seen in the blood. Concomitant infections with a Plasmodium tropiduri check for this species in other resources -like malaria parasite were seen and were sometimes extremely heavy.
