Phylogeny of Neisseria meningitidis isolates containing blaROB-1 and others with the same sequence types (ST-3587, 15379 or 13034) available in the PubMLST database as of April 21, 2020, based on a core genome alignment with recombinant regions removed. Isolates are labeled with the year and country of collection. Colored bars to the right of the phylogeny indicate the presence of antimicrobial resistance markers: penA mosaic allele (yellow), blaROB-1 (red), and gyrA T91I (blue). The scale bar is 10−5 substitutions per site. Branches with bootstrap percentages over 70% are labeled. The tree is rooted on a ST-23 isolate collected in the USA in 2003.
