Fig. 3 in Field and experimental evidence of a new caiman trypanosome species closely phylogenetically related to fish trypanosomes and transmitted by leeches

Fig. 3. Proposed life cycle of T. clandestinus and its developmental and morphological features in caiman blood and leeches. Giemsa-stained blood smears showed blood trypomastigotes of experimentally-infected Caiman yacare, and epi- and trypomastigotes found in the gut of one leech of the genus Haementeria sp. collected in the mouth of a wild Cayman yacare captured in the Pantanal wetland of Brazil. The caiman and the leech trypanosomes were molecularly identified as T. clandestinus. (a‾c) epimastigotes; (b) epimastigote dividing by binary fission; (d, g) short trypomastigote; (e,f) long and thin trypomastigotes. Arrow points to the long and thin posterior extremity of very long and slender trypomastigotes. K, kinetoplast; N, nucleus; F, flagellum.

Fig. 2. Phylogenetic tree (ML) based on gGAPDH sequences showing the Terrestrial and Aquatic clades of Trypanosoma and the positioning of T. clandestinus. The Crocodilian clade, which is formed by T. terena, T. ralphi, T. gray and Cay03 nests in the Terrestrial Clade whereas the Clandestinus clade comprising T. clandestinus nests in Aquatic clade. Typanosomatid genera other than Trypanosoma were used as outgroups in the phylogenetic trees (608 characters, Ln = —7611.897017). Numbers at nodes are bootstrap support (P/ML)>50% and Bayesian posterior probability>0.25 derived from 500 replicates.

Fig. 1. Geographical origin of crocodilian trypanosomes included in the V7V8 SSU rRNA dendrogram inferred to compare the barcode sequences between the new and known trypanosomes from crocodilians and other species of aquatic and semi aquatic hosts. The clade comprising T. clandestinus n. sp. nested into the Aquatic clade closely related to fish trypanosomes whereas sequences of the other new species formed the clade Cay03, which clustered with T. terena, T. grayi and T. ralphi in the Crocodilian Terrestrial clade. The host species and geographic origin and Genbank accession numbers of sequences from the crocodilian trypanosomes are shown in Table 1. Numbers at nodes are bootstrap support values>50% (P/ML) derived from 500 replicates.
