We investigated the prevalence of Staphylococcus aureus and methicillin-resistant S. aureus (MRSA) in 120 retail meat samples from 30 grocery stores in Baton Rouge, LA. S. aureus strains were recovered from 45.6% of pork samples and 20% of beef samples, whereas MRSA strains were isolated from six meat samples (five pork samples and one beef sample). The MRSA isolates were of two strain types (clones), one harboring Panton-Valentine leucocidin and belonging to pulsed-field gel electrophoresis type USA300 and the other one belonging to USA100.
我们调查了路易斯安那州巴吞鲁日30家杂货店120份零售肉类样本中金黄色葡萄球菌和耐甲氧西林金黄色葡萄球菌（MRSA）的流行情况。从45.6%的猪肉样本和20%的牛肉样本中分离出金黄色葡萄球菌菌株，而从6份肉类样本（5份猪肉样本和1份牛肉样本）中分离出MRSA菌株。MRSA分离株有两种菌株类型（克隆），一种携带杀白细胞素，属于脉冲场凝胶电泳类型USA300，另一种属于USA100。
