背景：德克萨斯州埃尔帕索和墨西哥华雷斯城是美墨边境人口最多的地区。方法：分别从埃尔帕索市2家医院和华雷斯市2家医院采集细菌样本，并按照ncls标准送往埃尔帕索市参考微生物实验室进行微生物鉴定和药敏试验。采用PCR检测了所有MRSA分离株中MecA基因的存在，以及SSCmec IV元素和ptonvalentine白细胞杀素的流行情况。结果：在埃尔帕索市和华雷斯市分别检出201株和128株金黄色葡萄球菌，其中MRSA在埃尔帕索市的流行率明显高于华雷斯市[89株（44.3%）比10株（7.8%）](p
Background: El Paso, Texas and Ciudad Juarez, Mexico comprise the largest U.S./Mexico border population.Methods: Bacterial samples were collected from two hospitals in El Paso and two in Ciudad Juarez and transported to a reference microbiology laboratory in El Paso for microbial identification and antimicrobial susceptibility testing according to NCCLS standards. The presence of the MecA gene, and the prevalence of both the SSCmec IV element and the Panton-Valentine leukocidin were investigated by PCR in all MRSA isolates.Results: A total of 201 isolates in El Paso and 128 in Ciudad Juarez of Staphylococcus aureus were identified, of those, MRSA were significantly more prevalent in El Paso than in Ciudad Juarez [89 (44.3%) versus 10 (7.8%) respectively (p
