FIG 2.

Phylogenetic tree based on concatenation of the seven MLST gene sequences of the 282 strains that were tested using the three multiplex PCRs. Branches of lineage I are in red and branches of lineage II are in blue. Clones defined based on MLST data are indicated with colored areas at the leaves. Colored areas around the tree indicate the serogroups defined with the PCR serogrouping method. Identification results based on the clonogrouping multiplex PCR method are indicated by rounded squares on the outer circle (see key). White stars, incomplete identifications; black stars, incorrect identifications.
