BACKGROUND: Resistance to macrolides in Streptococcus pneumoniae arises primarily due to Erm(B) or Mef(A). Erm(B) typically confers high-level resistance to macrolides, lincosamides and streptogramin B (MLS(B) phenotype), whereas Mef(A) confers low-level resistance to macrolides only (M phenotype). The purpose of this study was to investigate the incidence of macrolide resistance mechanisms in Canadian isolates...
