Fig. 2. Genetic relationship based on Bayesian Inference analysis of the small subunit nuclear ribosomal DNA (SSU) sequences of Echinocephalus spp. collected form sea snake, stingray and octopus in Australia determined in this study (bold). Nodal support is given as a posterior probability for BI analysis followed by bootstrap values for NJ analysis on this tree. Gnathostoma lamothei (Bertoni-Ruiz et al., 2011) was used as the outgroup, however the GenBank entry for this parasite is with its old name, Gnathostoma neoprocyonis Z96947. The scale bar indicates the number of inferred substitutions per nucleotide site.

Fig. 1 in Genetic characterization of Strongyloides fuelleborni infecting free-roaming African vervets (Chlorocebus aethiops sabaeus) on the Caribbean island of St. Kitts

Fig. 1. Schematic of the Strongyloides genotyping scheme referenced here Graphical representation a Strongyloides sp. genotyping scheme after the description of Barratt et al. (Barratt et al., 2019a; Barratt and Sapp, 2020). This scheme was expanded here to include haplotypes XVI and XVII of 18S HVR-I (indicated by a star) identified here from feral vervet monkeys living on the island of St Kitts (GenBank accessions in Table 3). Haplotype names shown in blue belong to S. fuelleborni and those shown in black belong to other Strongyloides species in accordance with this typing scheme. Haplotype sequences are provided in File S1. (For interpretation of the references to color in this figure legend, the reader is referred to the Web version of this article.)

Fig. 3 in Genetic characterization of Strongyloides fuelleborni infecting free-roaming African vervets (Chlorocebus aethiops sabaeus) on the Caribbean island of St. Kitts

Fig. 3. Neighbor-Joining tree generated from St Kitts S. fuelleborni genotypes and other Strongyloides types This tree was generated by applying the Neighbor-Joining clustering method (Saitou and Nei, 1987) to a pairwise distance matrix computed using Barratt's heuristic from 285 Strongyloides genotypes, including 48 from St. Kitts vervets. Branches are colored according to their cluster membership (A through H) as defined by Ko et al. (2022). We also introduce S. fuelleborni type H (light pink) from St. Kitts vervets, noting that an H-type isolate was found previously in a human from Guinea-Bissau (pink triangle). Divergent S. fuelleborni types described by Ko et al. (2022) were also analyzed (bright green branches without a cluster letter) from Siamang, Douc, and Francois' langur housed in zoological parks in Japan. A version of this same tree with isolate names shown on the branch tips is provided in File S3; Tree B.

Fig. 2. Hierarchical tree of clustered distances generated from genotyped S. fuelleborni from St Kitts vervets and other Strongyloides sp. genotypes This unrooted tree was generated using Wards method (Ward, 1963) to cluster a pairwise distance matrix computed from 285 Strongyloides genotypes, including 48 from St. Kitts vervets. Branches are colored according to their cluster membership (A through H). We introduce S. fuelleborni type H (pink star) identified from St. Kitts vervets, noting that an H-type isolate was found previously in a human from Guinea-Bissau. Colored peripheral bars reflect the host species from which isolates were derived; dog (Do), human (Hu), chimpanzee (Ch), lorises (Lo), long-tailed macaques (Lt), pig-tailed macaques (Pt), Japanese macaques (Jm), proboscis monkeys (Pr), silvered leaf monkeys (Sl), orangutans (Or), Rhesus macaques (Rh), St Kitts (white star) vervets (Ve), gorilla (Go), and baboon (Ba). Divergent S. fuelleborni types described by Ko et al. (2023) were also clustered (green circle and branches) from Siamang (Si), Douc (Do), and Francois' langur (Fr) housed in zoological parks in Japan. The black bar and black star indicate S. stercoralis reference strain PV001. Strongyloides stercoralis types A and B, are shown with red and blue branches respectively. The loris clade is shown in light blue. The S. stercoralis and loris clades clustered here for comparison are shaded in a gray background. A version of this same tree with isolate names shown on the branch tips is provided in File S3; Tree A.
