^aFor several isolates, previous reports (5, 8) indicated M serological types that are discordant with the emm sequence types presented here. 

^bImp, impetigo; NP, nasopharyngeal site; ND, not determined. 

^cAP52 and AP53 are also designated CV686 and CV265, respectively (31). AP53 is the strain from which Emm53 (PAM) was originally derived (4).
