Introduction: Methicillin-resistant Staphylococcus aureus (MRSA) is an important clinical problem. In 2005, a livestock-associated MRSA clone was described, named CC398, being mostly associated with pigs, and causing colonization and infection in pigs and in related humans. The prevalence of these strains in food-producing pigs raised concerns about the possibility of MRSA-CC398 being a foodborne pathogen. The objective of this study was to investigate the presence of S. aureus and MRSA in 141 carcasses of pigs at three slaughterhouses of Portugal, discarded from the food chain by signs of infection, and to characterize the recovered isolates.

简介：耐甲氧西林金黄色葡萄球菌（MRSA）是一个重要的临床问题。2005年，描述了一个与牲畜相关的MRSA克隆，名为CC398，主要与猪相关，并在猪和相关人类中引起定植和感染。这些菌株在食品猪中的流行引起了人们对MRSA-CC398是否为食源性病原体的担忧。这项研究的目的是调查葡萄牙三个屠宰场的141头猪的尸体中金黄色葡萄球菌和MRSA的存在，并通过感染的迹象将其从食物链中丢弃，并鉴定回收的分离物。
