Dissemination of Macrolide-Resistant <i>Streptococcus pneumoniae</i> Isolates Containing Both <i>erm</i> (B) and <i>mef</i> (A) in South Korea

Abstract

Macrolide resistance was detected in 64 of 77 (83.1%) Streptococcus pneumoniae isolates from South Korea. Seven (10.9%) isolates contained only mef(A), 32 (50%) contained only erm(B), and 25 (39.1%) contained mef(A) and erm(B). Nineteen isolates containing mef(A) and erm(B) belonged to serotype 19F, and seven isolates were identical to the Taiwan(19F)-14 clone.
