FIG 2.

Inferred genetic relationships between strains of serotype IV group B Streptococcus (GBS) causing invasive disease in adults in Manitoba and Saskatchewan. A neighbor-joining phylogenetic tree was constructed using the concatenated sequences of the 7 genes (adhP, pheS, tkt, sdhA, glcK, glnA, atr) used in the multilocus sequence typing scheme. Colored circles represent the six different sequence types (STs) identified among serotype IV strains isolated from adult patients in Manitoba and Saskatchewan. Circle size is proportional to the number of isolates (ST3, n = 2; ST196, n = 1; ST452, n = 4; ST459, n = 76; ST710, n = 1; ST711, n = 1).
