Phenotypic and molecular methods were used to characterize the antibiotic resistance of 64 clinical isolates of Staphylococcus haemolyticus. By PCR of the mecA gene, 87% were found to be methicillin resistant. Approximately 55% harbored staphylococcal cassette chromosome mec element (SCCmec) type V, and only one SCCmec type IV. Many isolates (75%) displayed multiresistance, and pulsotype analysis showed a high diversity.
采用表型和分子方法对 64 株溶血葡萄球菌临床分离株的抗生素耐药性进行了研究。通过 mecA 基因 PCR,发现 87%的菌株对甲氧西林耐药。大约 55%的菌株携带葡萄球菌盒式染色体 mec 元件(SCCmec)类型 V,只有 1 株为 SCCmec 类型 IV。许多分离株(75%)表现出多药耐药性,脉冲场凝胶电泳分析显示出高度多样性。
