Antimicrobial resistance and SCCmec genotype of methicillin-resistant Staphylococcus aureus / 国际检验医学杂志

Objective To investigate antibiotic resistance and Staphylococcal cassette chromosome mec (SCC-mec) genotype of methicillin-resistant Staphylococcus aureus (MRSA)in Dalian Area .Methods Antimicrobial susceptibility of MRSA was detected by Kirby-Bauer method and SCCmec genotype by multiple PCR method .Results 38 strains of MRSA were all multidrug-resistant strains ,but susceptible to vancomycin and chloramphenicol .The most common SCCmec genotype was type Ⅱ (86 .84% ) ,type Ⅲwas in the second place(10 .53% ) ,and unidentified type accounted for 2 .6% .Conclusion MRSA strains in Dalian area are charac-terized by multidrug resistance ,type Ⅱ is the most common SCCmec genotype .
