Analysis of SCCmec genotyping and antimicrobial susceptibility tests in methicillin resistant Staphylococcus aureus / 中华实验和临床病毒学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the SCCmec genotyping, subtype and antimicrobial susceptibility tests in methicillin resistant staphylococcus aureus to guide the clinical treatment and provide the proof for molecular epidemiology.</p><p><b>METHODS</b>To detect mecA gene and SCCmec genetyping and subtype in 50 MRSA by PCR. According to CLSI's guideline, antimicrobial susceptibility tests were performed with disk diffusion.</p><p><b>RESULTS</b>All 50 MRSA had mecA genes. 45 strains were SCCmec III types; 3 strains were SCCmec III A types; 2 strains were SCCmec II types. There were no SCCmec I and SCCmec IV types. SCCmec II, SCCmec III and SCCmec III A type strains were all multiresistant.</p><p><b>CONCLUSION</b>50 MRSA are all multiresistant. SCCmec III are the main types.</p>
