Molecular characterization of Group A streptococcal isolates causing scarlet fever and pharyngitis among young children: a retrospective study from a northern Taiwan medical center.
Little information is available on the differences in frequency of pyrogenic exotoxin genes between strains of group A streptococci that cause scarlet fever and those that cause pharyngotonsillitis in children in Taiwan. This study retrospectively monitored the presence of pyrogenic exotoxin genes, the emm typing, and the susceptibility of macrolide drugs in Streptococcus pyogenes isolated from children diagnosed with scarlet fever and pharyngotonsillitis in northern Taiwan. ⋯ There were no significant differences in frequencies of the spe genes between S. pyogenes isolates from patients with scarlet fever and patients with pharyngotonsillitis. The most common emm type was emm12. Low erythromycin resistance in S. pyogenes was observed.
