RNA viruses play an important role in Leishmania biology and virulence. Their presence was documented three (out of four) subgenera. Sauroleishmania reptiles remained the only underinvestigated group. In this work, we analyzed viral occurrence spp. detected out seven isolates under study. These were two families-Narnaviridae Totiviridae. Phylogenetic inferences demonstrated that totiviruses from L. adleri tarentolae group together within a larger cluster LRV2s, while narnavirus gymnodactyli...
Abstract Trypanosomatids (Euglenozoa) are a diverse group of unicellular flagellates predominately infecting insects (monoxenous species) or circulating between and vertebrates plants (dixenous species). Monoxenous trypanosomatids harbor wide range RNA viruses belonging to the families Narnaviridae, Totiviridae, Qinviridae, Leishbuviridae, putative tombus-like viruses. Here, we focus on subfamily Blastocrithidiinae, previously unexplored divergent monoxenous comprising two related genera:...
Abstract Background Trypanosomatids are parasitic flagellates well known because of some representatives infecting humans, domestic animals, and cultural plants. Many trypanosomatid species bear RNA viruses, which, in the case human pathogens Leishmania spp., influence course disease. One close relatives leishmaniae, Leptomonas pyrrhocoris , has been previously shown to harbor viruses groups not documented other trypanosomatids. At same time, this a worldwide distribution high prevalence...
Leishmania spp. represent human pathogens that cause leishmaniasis, a widespread parasitic disease with mild to fatal clinical manifestations. Some strains of leishmaniae bear leishmaniaviruses (LRVs), and this has been shown aggravate course.
Leishmania RNA virus 1 (LRV1) is commonly found in South American parasites belonging to the subgenus Viannia, whereas 2 (LRV2) was previously thought be restricted Old-World pathogens of Leishmania.In this study, we investigated presence LRV2 strains (L.) infantum, causative agent visceral leishmaniasis (VL), originating from different hosts, clinical forms, and geographical regions.A total seventy-one isolates were screened for using semi-nested reverse transcription-polymerase chain...
Leishmania is a genus of the family Trypanosomatidae that unites obligatory parasitic flagellates causing variety vector-borne diseases collectively called leishmaniasis. The symptoms range from relatively innocuous skin lesions to complete failures visceral organs. disease exacerbated if parasite harbors RNA viruses (LRVs) Pseudototiviridae . Screening novel isolate L braziliensis , we revealed it possesses not toti-, but bunyavirus Leishbuviridae To best our knowledge, this very first...
