Susceptibility phenotype of Staphylococcus aureus and methicillin-resistant Staphylococcus aureus SCCmec genotyping / 中国基层医药

ABSTRACT

Objective To explore the characteristics of drug resistance of Staphylococcus aureus and methicillin-resistant Staphylococcus aureus SCCmec genotyping.Methods The disc agar diffusion method was taken to test 500 Staphylococcus aureus susceptibility and methicillin-resistant Staphylococcus aureus by multiplex PCR SCCmec genotyping assay.Results The rate of methicillin-resistant Staphylococcus aureus was 40.0％ (200/500),and had a high resistance rate to clindamycin,sulfamethoxazole and tetracycline,which celebrate neomycin and quinolones resist ance rates,while a completely resistant to clindamycin and β-lactam drug,and other performance of multi-drug resist ance,resistance to vancomycin had not uncovered any prime strains; through SCCmec genotyping of MRSA,which mainly SCCmec Ⅲ and SCCmec Ⅳ well SCCmec Ⅴ type,another seven unclassified.Conclusion The separation of Staphylococcus aureus,methicillin-resistant Staphylococcus aureus performance of multiple drug resistance performance of its SCCmec genotyping is SCCmec Ⅲ type and SCCmec Ⅳ and SCCmec Ⅴ type.
