Lankesterella parasites of passerines: phylogeny and host specificity

Popis výsledku v původním jazyce

Lankesterella parasites are blood coccidians that have recently gained attentionas their records in common passerine species emerge. To date, their occurrencehas been molecularly confirmed in several passerine genera, mainly amongmembers of the families Paridae and Acrocephalidae. Despite their relatively highprevalence in some host populations, their life cycles remain unclear, mosquitoesbeing the proposed vectors. The aim of this study was to reveal Lankesterella hostspecificity, focusing mainly on parasites of Tit and Warbler species. We havesequenced the 18S rRNA gene of Lankesterella from 35 individuals belonging toeight different host species. Phylogenetic analysis revealed that passerineLankesterella are host-specific, with specificity at the genus or species level.Genus Lankesterella appeared monophyletic although with low support. AvianLankesterella appeared closely related to species from amphibians and 1 lizardlineage. Lineages from Warblers formed a clade with 4 species from theAcrocephalidae family; within it, lineages from Sedge Warbler formed a sub-clade.Lineages found in three Tit species formed their own specific clades. Newlyreported hosts (Common Starling, Eurasian Jay) had their own lineages, as wellas lineages resulting from previous occasional findings in other passerines (SnowBunting), formed host-specific clades. Besides Lankesterella, Isospora sequenceswere obtained from avian blood as well, pointing out the need for barcoding.
