Phylogenomic tree of Neisseria gonorrhoeae isolates with azithromycin MICs of >2 μg/mL, 2004–2017. A) MLST ST1580 and NG-MAST genogroup 470 isolates from Argentina in the context of selected isolates from Scotland (2004–2005), the United States (2016), Australia (2017), Brazil (2015–2016), and the United Kingdom (2014–2017). B) MLST ST9363 and NG-MAST genogroup G12302 isolates from Argentina in the context of selected isolates from Australia (2017), the United States (2014–2017), Brazil (2015–2016), Norway (2017), and Canada (2013–2014). Lane 1, 23S rRNA; lane 2, mtrR; lane 3, mtrD; lane 4, MLST. Labels indicate isolate identity; font colors indicate country of isolation. Bar colors indicate distribution of mutations. Insets indicate relationship of sequences to larger phylogenetic tree. Scale bar indicates substitutions per site. MLST, multilocus sequence typing; NG-MAST, N. gonorrhoeae multiantigen sequence typing.
