Abstract

We characterized 182 Streptococcus dysgalactiae subsp. equisimilis isolates and analyzed the epidemiological data on the corresponding infections. stG6, stG485, and stG6792 were the 3 most prevalent invasive emm types among the 27 different emm types recovered. High rates of antimicrobial resistance were observed for macrolides (26.4%) and tetracycline (34.6%).

(B) Comparison of invasive and noninvasive emm types of S. dysgalactiae subsp. equisimilis isolates. In both panels A and B, the 12 other emm types were stG840 (n = 2), stG4831 (n = 2), stG5420 (n = 2), stG7882 (n = 2), stC58 (n = 1), stC6979 (n = 1), stC7934 (n = 1), stC9431 (n = 1), stCNSRT2 (n = 1), stG1750 (n = 1), stG5063 (n = 1), and stL2764 (n = 1).
