Main Article

Figure 2

Maximum-likelihood phylogeny of zoonotic soil-transmitted helminths from human infections, Gabon. A) Necator spp. hookworms; color-coded groups are labeled per nomenclature by Hasegawa et al. (4). B) Strongyloides fuelleborni fuelleborni threadworms; color-coded groups represent geographic regions. Trees are based on cox1 sequences and were created by using MEGA 11 (https://www.megasoftware.net) and Bayesian inference using MrBayes (https://github.com/NBISweden/MrBayes). Bayesian posterior probability and maximum-likelihood bootstrap support percentages (1,000 bootstrap replicates) are indicated at the nodes. Bold font and black circles indicate sequences obtained in this study. Published sequences are annotated with the country of origin, host species, and GenBank accession numbers. Scale bars indicate nucleotide substitutions per site. CAR, Central African Republic
