Distribution of GAS isolates recovered from normally sterile sites in Portugal during 2010–2015 according to emm cluster and emm type. Numbers inside the bars represent the emm types included in each cluster. White bars include emm types with <5 isolates [E4: emm102 (n = 2), emm2, emm73, emm84, and emm169 (each n = 1); E3: emm118 (n = 2), emm9, emm82, and emm103 (each n = 1); E6: emm11 (n = 4), emm81 (n = 2), emm85, emm94, and emm99 (each n = 1); E1: emm78 (n = 2) and emm165 (n = 1); E2: emm90, emm110 (each n = 2), emm50, emm66, and emm104 (each n = 1)]. M5 and M6 are singletons belonging to clade Y. “Other” includes emm clusters or singletons with <5 isolates each [D4: emm70 (n = 2), emm33, and emm43 (each n = 1); D2: emm71 (n = 1); D3: emm123 (n = 1); M18: emm18 (n = 1)].
