Macrolide- and telithromycin-resistant Streptococcus pyogenes, Belgium, 1999-2003

Emerg Infect Dis. 2005 Jun;11(6):939-42. doi: 10.3201/eid1106.041247.

Abstract

We found a 13% macrolide resistance in 3,866 Streptococcus pyogenes isolated from tonsillopharyngitis patients; 59% macrolide-resistant isolates were distributed in 5 clones, suggesting the importance of both resistance gene transfer and clonal dissemination in the spread of these organisms. We also report one of the largest collections of telithromycin-resistant isolates.
