Seventy-one percent of 76 methicillin-resistant Staphylococcus aureus (MRSA) strains isolated from two medical centers in El Paso, Texas, represent three similar pulsed-field gel electrophoresis types. Overall, six pulsed-field types were identified represented by multilocus sequence/staphylococcal chromosomal cassette DNA mec (SCCmec) types: ST5-MRSA-II; ST36-MRSA-II; ST8 (untypeable SCCmec); and a newly described clonal cluster 8 strain, ST507-MRSA-IV. This study demonstrates the presence of multiple-antibiotic-resistant epidemic MRSA clones in El Paso.
从得克萨斯州埃尔帕索市的两个医疗中心分离出的76株耐甲氧西林金黄色葡萄球菌(MRSA)菌株中,71%属于三种相似的脉冲场凝胶电泳类型。总体而言,共鉴定出六种脉冲场类型,由多位点序列/葡萄球菌染色体盒式DNA mec(SCCmec)类型代表:ST5-MRSA-II;ST36-MRSA-II;ST8(无法分型的SCCmec);以及一个新描述的克隆簇8菌株,ST507-MRSA-IV。这项研究证明了埃尔帕索市存在多重耐药性的流行MRSA克隆。
