Detection of erm and msrA genes in staphylococci with resistance to erythromycin

Aim To survey the prevalence of erm and msrA genes in staphylococci with resistance to erythromycin isolated.Methods The resistance gene of ermA,ermB,ermC and msrA in 158 S.aureus and 141 S.epidermidis with resistence to erythromycin were detected by PCR.Results The prevalence of ermA,ermB,ermC and msrA was 3.2%,6.9%,39.9%,6.9% respectively in S.aureus,and 2.1%,2.1%,55.3%,14.2% in S.epidermidis,respectively.A few isolates carried two genes.Conclusion The most prevalent resistance gene was ermC in staphylococci isolates with resistance to erythromycin.
