FIG 1.

Whole-genome-based core SNP phylogenomic tree of N. gonorrhoeae strains based on maximum likelihood. NG-MAST types, antimicrobial susceptibility, and antimicrobial resistance molecular markers are indicated. Antimicrobial susceptibility to ceftriaxone (CRO), cefixime (CFM), and azithromycin (AZM) is shown. Red in the molecular marker columns (rightmost columns) represents presence of the marker. For penA, red represents a mosaic allele. In the penA column, WT, wild type; I*, penA nonmosaic I allele with a P413S substitution; II*, nonmosaic II allele with A505V; II**, nonmosaic II allele with A502V; V*, nonmosaic V allele with Y201H, G202A, E203G, D204E, and Q214E; XXXIV*, mosaic XXXIV allele with A502P.
