[[abstract]]Our multicenter nationwide surveillance data indicated that erythromycin (ERY)-resistance among Group A Streptococcus (GAS) in Taiwan declined from 53.1% in 1998-2000 to 14.6% in 2002-2004 and 10.7% in 2006-2010 (p <0.01). The present study aimed to assess the epidemiology of GAS in Taiwan and identify factors associated with ERY-resistance. All 127 ERY-resistant (ERY-R) and 128 randomly selected ERY-susceptible (ERY-S) isolates from 1998-2010 were emm typed. ERY-R isolates were also characterized by ERY-resistance phenotype and mechanisms, and pulsed-field gel electrophoresis (PFGE). Multilocus sequence typing was performed on selected ERY-R isolates. The predominant emm types in ERY-R isolates were emm22 (33, 26.0%), emm12 (24...
