Figure 3.

Distribution of virulence-related factors by emm type. The proportion of pharyngitis (blue) or invasive (red) isolates that were positive for inactivating mutations in the covS gene (COVS_NULL) (A), the Pnga 3 - Clade 3 up-regulated promoter of the nga operon (PNGA3) (B), and streptococcal pyrogenic exotoxin C (SPE_C) (C) is shown. The x-axis is ordered by decreasing y-values of the invasive (red) group. The point size is proportional to the isolate count. There were no emm92 pharyngitis isolates so no proportion existed. Only the 15 most frequent emm types each containing 10 or more isolates are shown.
