a Linear maps of the mitochondrial genomes of Necator americanus. Outline arrows indicate the positions and direction of transcription of protein- and rRNA-coding genes; hairline arrows indicate the position of tRNA-coding genes (trn). Black solid horizontal lines and colored horizontal lines below depict average nucleotide and amino acid identities of aligned protein and rRNA coding among three N. americanus isolates from China (NC_003416 and this study) and Togo (AJ556134). atp6, adenosine triphosphatase subunit 6; cox, cytochrome c oxidase complex; cytb, cytochrome b; nad, nicotinamide dehydrogenase complex; rrnL, large subunit rDNA; rrnS, small subunit rDNA. b The phylogenetic tree of 14 available mt genomes of hookworms in the GenBank database to date (June 30, 2021) using ML and BI methods based on 12 protein-coding genes. Numbers above branches represent the bootstrap values and Bayesian posterior probabilities. Only bootstrap values above 60 and posterior probabilities above 0.6 are shown
