FIG 2.

Urogenital N. meningitidis isolates primarily fall within a single, highly related clade. An approximate maximum likelihood tree of core genome alignment of St. Louis and select Neisseria isolates with tree branch lengths of >0.0001 is shown. Two urogenital isolates collected from St. Louis fall outside of this clade and are distantly related to the ST-11 clonal complex. All isolates that tested positive for N. gonorrhoeae fall into a clade with other urogenital N. meningitidis isolates. The source is indicated by color of the tip, and Aptima test results are indicated by the shape of tip. Ng, N. gonorrhoeae.
