Sir,
Although erythromycin resistance in streptococci is predominantly due to target site modification by rRNA methylases (encoded by erm genes) or drug efflux (encoded by mef genes), novel resistance mechanisms continue to emerge.1 Furthermore, susceptibility to macrolides, lincosamides, streptogramins and ketolides varies depending on the distribution of different erythromycin resistance mechanisms.1 Therefore, phenotypic and genotypic erythromycin resistance surveillance data are required as an adjunct in determining therapy for streptococcal infections. In the UK, erythromycin resistance in Lancefield group B (GBS), C (GCS) and G (GGS) streptococci is increasing, but data on
