Lankesterella (Apicomplexa, Lankesterellidae) Blood Parasites of Passeriform Birds: Prevalence, Molecular and Morphological Characterization, with Notes on Sporozoite Persistence In Vivo and Development In Vitro.

摘要: Recent studies confirmed that some Hepatozoon-like blood parasites (Apicomplexa) of birds are closely related to the amphibian parasite Lankesterella minima. Little is known about biology these pathogens in birds, including their distribution, life cycles, specificity, vectors, and molecular characterization. Using samples 641 from 16 species, we (i) determined prevalence diversity naturally infected birds; (ii) investigated development kabeeni laboratory-reared mosquitoes, Culex pipiens forma molestus Aedes aegypti; (iii) tested experimentally susceptibility domestic canaries, Serinus canaria, this parasite. This study combined morphological diagnostic methods 11% Acrocephalidae lineages with a certain degree host specificity two new species (Lankesterella vacuolata n. sp. macrovacuolata sp.) were found characterized. (formerly Hepatozoon kabeeni) was re-described. canaria resistant after various experimental exposures. sporozoites rapidly escaped cells vitro. Sporozoites persisted for long time mosquitoes (up 42 days post exposure). Our demonstrated high showed several avian parasites, fact, belong genus.
