Phylogenetic trees of isolate from novel Mycobacterium gordonae–like infection in a 63-year-old man in China (X7091) and reference isolates. A) Evolutionary tree involving 16S rRNA gene (1,067 positions) of isolate X7091 and 26 Mycobacterium strains. Tree constructed using the maximum-likelihood method and Tamura-Nei model with 500 bootstrap replications in MEGA X (https://www.megasoftware.net). We selected Norcadia seriolae ATCC 43993 as the outgroup. B) Core genome–based maximum-likelihood phylogeny of isolate X7091 and other M. gordonae–like strains analyzed by Roary (https://sanger-pathogens.github.io/Roary) and constructed with a general time-reversible plus gamma maximum model (500 bootstrap replications) using the RaxML tool (14). We selected Mycobacterium marinum ATCC 927 as the outgroup. Scale bars indicate the number of nucleotide substitutions per site.
