"We identified erm(A)-harbouring Streptococcus pyogenes that expressed three variant phenotypes: (1) low-level resistance to erythromycin (MICs 1-4 mg/L) but high azithromycin MICs in absolute terms (16-64 mg/L; n = 6); (2) same as (1) but with a high clindamycin MIC (256 mg/L; n = 1); and (3) high-level constitutive MLS (cMLS) resistance (n = 1). Here we analysed the genetic basis of these novel phenotypes," researchers in Antwerp, Belgium report.
"The presence of erm(A) and the absence of macrolide/lincosamide resistance genes erm(B), mef and cfr were confirmed by PCR. erm(A), 23S rRNA, L4 and L22 genes were sequenced. Mutant erm(A) genes were cloned and...
