Haemogregarina sp. (Apicomplexa: Adeleorina) from the gecko Tarentola annularis in the Sudan: fine structure and life-cycle trials.

The ubiquitous gecko Tarentola annularis in the area around Khartoum, Sudan, was found to be infected with Haemogregarina sp., with merogonic stages in its pulmonary endothelial cells and gamonts in its erythrocytes. The fine structure of Haemogregarina meronts, merozoites and gamonts revealed great conformity with the micromorphology of similar stages of other apicomplexan parasites. The unsuccessful transmission of Haemogregarina gamonts to the mosquitoes Aedes aegypti, Culex quinquefasciatus and Anopheles stephensi is also reported.
