摘要：

RNA viruses play an important role in Leishmania biology and virulence. Their presence was documented in three (out of four) Leishmania subgenera. Sauroleishmania of reptiles remained the only underinvestigated group. In this work, we analyzed the viral occurrence in Sauroleishmania spp. and detected RNA viruses in three out of seven isolates under study. These viruses were of two families-Narnaviridae and Totiviridae. Phylogenetic inferences demonstrated that totiviruses from L. adleri and L. tarentolae group together within a larger cluster of LRV2s, while a narnavirus of L. gymnodactyli appeared as a phylogenetic relative of narnaviruses of Blechomonas spp. Taken together, our work not only expanded the range of trypanosomatids that can host RNA viruses but also shed new light on the evolution and potential routes of viral transmission in these flagellates.
