Abstract excerpt

Using sequence analysis to detect variation within the hypervariable M protein N terminus, we found 41 emm types encompassing 81 subtypes, among 1064 consecutive invasive group A streptococcus isolates from a recent multistate, population-based surveillance. Seventeen of the 30 emm types represented by multiple isolates displayed multiple subtypes. Most subtypes differed from reference strain emm sequences as a...
