Differences in the DNA sequences in the upstream attenuator region of erm(A) in clinical isolates of Streptococcus pyogenes and their correlation with macrolide/lincosamide resistance.


ABSTRACT: The regulatory regions of 52 erm(A) [formerly erm(TR)] clinical Streptococcus pyogenes isolates were studied. Differences in the upstream regulatory region of erm(A) correlated with macrolide/lincosamide resistance patterns. Nine macrolide/lincosamide/streptogramin B-resistant isolates had changes in the leader sequence of erm(A) including base changes, insertions, or deletions. Isolates were also emm typed.
