“…( Megatrypanum) incertum [6,7]. The bat restricted Stricticimex brevispinosus was found to be infected by a Megatrypanum trypanosome in Africa [48]. In addition, sand flies were incriminated as vectors of T. (Megatrypanum) leonidasdeanei in South America [49].…”

Trypanosoma livingstonei: a new species from African bats supports the bat seeding hypothesis for the Trypanosoma cruzi clade

BackgroundBat trypanosomes have been implicated in the evolutionary history of the T. cruzi clade, which comprises species from a wide geographic and host range in South America, Africa and Europe, including bat-restricted species and the generalist agents of human American trypanosomosis T. cruzi and T. rangeli.MethodsTrypanosomes from bats (Rhinolophus landeri and Hipposideros caffer) captured in Mozambique, southeast Africa, were isolated by hemoculture. Barcoding was carried out through the V7V8 region of Small Subunit (SSU) rRNA and Fluorescent Fragment Length barcoding (FFLB). Phylogenetic inferences were based on SSU rRNA, glyceraldehyde phosphate dehydrogenase (gGAPDH) and Spliced Leader (SL) genes. Morphological characterization included light, scanning and transmission electron microscopy.ResultsNew trypanosomes from bats clustered together forming a clade basal to a larger assemblage called the T. cruzi clade. Barcoding, phylogenetic analyses and genetic distances based on SSU rRNA and gGAPDH supported these trypanosomes as a new species, which we named Trypanosoma livingstonei n. sp. The large and highly polymorphic SL gene repeats of this species showed a copy of the 5S ribosomal RNA into the intergenic region. Unique morphological (large and broad blood trypomastigotes compatible to species of the subgenus Megatrypanum and cultures showing highly pleomorphic epimastigotes and long and slender trypomastigotes) and ultrastructural (cytostome and reservosomes) features and growth behaviour (when co-cultivated with HeLa cells at 37°C differentiated into trypomastigotes resembling the blood forms and do not invaded the cells) complemented the description of this species.ConclusionPhylogenetic inferences supported the hypothesis that Trypanosoma livingstonei n. sp. diverged from a common ancestral bat trypanosome that evolved exclusively in Chiroptera or switched at independent opportunities to mammals of several orders forming the clade T. cruzi, hence, providing further support for the bat seeding hypothesis to explain the origin of T. cruzi and T. rangeli.

“…However, they may have a potential role in disease transmission. Closely related bat bug species belonging to family Cimicidae are competent or suspected vectors of several pathogens, such as Trypanosoma , Bartonella , and Kaeng Khoi virus (Gardner & Molyneux, 1988; Reeves et al, 2005; Salazar et al, 2015; Van Den Berghe et al, 1963; Williams et al, 1976). The vector of Nycteria (Haemosporidia) parasites, which have been shown to infect, e.g., Rhinolophidae and Nycteridae species (Schaer et al, 2015), is not known and as some polyctenids parasitize these families, it is possible that they play a vectorial role in Nycteria transmission.…”

Polyctenidae bugs are rarely studied, hematophagous, and highly specialized ectoparasites of bats. There are only 32 described species worldwide, including six species in the Afrotropical region. Knowledge on these parasites is limited, and most studies are restricted to the New World polyctenid species. Here we report additional records of Adroctenes horvathi from Kenya and South Africa, as well as Hypoctenes faini from Rwanda. We present an updated list of published polyctenid records in the Afrotropical region indicating their host specificity and their geographical distribution. We report global infection patterns and sex ratio of polyctenids based on previously published data, including Old and New World species. Lastly, we demonstrate the first molecular phylogeny of Polyctenidae, showing their phylogenetic relationship with the closely related family Cimicidae.

“…Furthermore, Trypanosoma spp. in Schizotrypanum clade were detected from a bat bug ( Stricticimex brecispinosus ) in Burundi, Africa (Van den Berghe et al, 1963). Thus, investigation of bat bugs and other blood-sucking insects in the cave is required to determine particular vector arthropods for the Trypanosoma spp.…”

Bat trypanosomes consist of more than 30 trypanosome species from over 70 species of bats. Recent studies suggest that bats play a role in disseminating trypanosomes from African continent to the terrestrial mammals both in the Afrotropic-Palearctic Ecozones and Nearctic Ecozone. However, the diversity, distribution, and evolution of bat trypanosomes are still unclear. To better understand their evolution, more genetic data of bat trypanosomes from a variety of locations are required. During a survey of Borrelia spp. of bats inhabiting a cave in Zambia, we observed flagellate parasites from 5 of 43 hemocultures. Sequence and phylogenetic analyses of the glycosomal glyceraldehyde 3-phosphate dehydrogenase gene ( gGAPDH ; 572 bp) and the 18S ribosomal RNA gene (18S rRNA gene; 1,079–1,091 bp) revealed that all were Trypanosoma spp. belonged to the Trypanosoma cruzi clade. Three and two of them exhibited the similarity with T. conorhini and T. dionisii , respectively. The present study provides the first genetic data on Trypanosoma spp. of bats inhabiting Zambia.
