This study was directed at characterizing the genetic elements carrying the methylase gene erm(B), encoding ribosome modification-mediated resistance to macrolide, lincosamide, and streptogramin B(More)
Sixty-three recent Italian clinical isolates of Streptococcus pyogenes resistant to both erythromycin (MICs >or=1 microg/ml) and tetracycline (MICs >or= 8 microg/ml) were genotyped for macrolide and(More)
In Streptococcus pyogenes, inducible erythromycin (ERY) resistance is due to posttranscriptional methylation of an adenine residue in 23S rRNA that can be encoded either by the erm(B) gene or by the(More)
