First investigation of blood parasites of bats in Burkina Faso detects Hepatocystis parasites and infections with diverse Trypanosoma spp.

Bats are hosts to a large diversity of eukaryotic protozoan blood parasites that comprise species of Trypanosoma and different haemosporidian parasite taxa and bats have played an important role in the evolutionary history of both parasite groups. However, bats in several geographical areas have not been investigated, including in Burkina Faso, where no information about malaria parasites and trypanosomes of bats exists to date. In this study, we collected data on the prevalence and the phylogenetic relationships of protozoan blood parasites in nine different bat species in Burkina Faso. Hepatocystis parasites were detected in two species of epauletted fruit bats, and a relatively high diversity of trypanosome parasites was identified in five bat species. The phylogenetic analyses recovered the trypanosome parasites of the bat species Rhinolophus alcyone and Nycteris hispida as close relatives of T. livingstonei , the trypanosome infections in Scotophilus leucogaster as closely related to the species T. vespertilionis and the trypanosomes from Pipistrellus nanulus and Epomophorus gambianus might present the species T. dionisii. These findings of the first investigation in Burkina Faso present a first snapshot of the diversity of protozoan blood parasites in bats in this country.
