FIG. 1.

Neighbor-joining tree constructed from the concatenated sequences of the 7 MLST genes described in the text. The 29 previously identified CgA isolates are shown with shaded backgrounds. Serogroups are indicated for the CgA isolates. The inset shows a dendrogram based on Dice distance coefficient measurements of PFGE banding patterns among the 21 isolates belonging to the ST69 complex. *, no PFGE data available; **, ST69 complex members, not ST69 (see Table 2); †, prototype human uropathogenic CgA strain ATCC BAA-457.
