Phylogenetic analysis of Ancylostoma spp. in study of A. ceylanicum hookworm, rural Papua New Guinea, 2020. Analysis is based on the internal transcribed spacer sequence regions 1 and 2 and conducted with the maximum-likelihood method, using the Kimura 2-parameter model. Model selection was based on penalized-likelihood information criteria. The phylogenetic tree was visually adjusted using Interactive Tree of Life version 7.2.2 (https://itol.embl.de). Values at branch nodes indicate bootstrap support values (1,000 replicates). A. braziliense was used as an outgroup to root the tree. GenBank accession numbers are shown; asterisks (*) denote sequences identified in this study (accession nos. PV530493–96). We used A. ceylanicum (accession no. PV530497) as a positive control. Dash (–) indicates that no information was available for a particular attribute of the strain. Scale bar represents 0.01 substitutions per site.
