Phylogenetic tree and antimicrobial resistance network analysis from study of antimicrobial-resistant Neisseria gonorrhoeae of public health concern, New South Wales, Australia, 2022–2024. A) Phylogenetic tree and isolate data. Ninety-three of the 94 isolates met the quality mapping criteria. B) Network analysis of cases with high-level resistance to azithromycin, with nodes colored according to acquisition source. C) Network analysis of cases with decreased susceptibility to ceftriaxone, with nodes colored according to acquisition source. Azi, azithromycin; CRO, ceftriaxone; DS, decreased susceptibility; HLR, high-level resistance; MLST, multilocus sequence type.
