Livestock-associated methicillin-resistant Staphylococcus aureus (LA-MRSA) has emerged among pigs in many countries. MRSA in the pig population constitute a reservoir with risk for transmission to humans in close contact with pigs. Absence of MRSA in the top of the breeding pyramid would prevent spread to the rest of the pig population. The aim of this study was to investigate the occurrence of MRSA in nucleus and multiplying pig herds in Sweden. All nucleus and multiplying pig herds in Sweden present in 2011 (= 53) and 2014 (= 39) were sampled for MRSA. MRSA was not detected either in 2011 or in 2014. That MRSA was not detected in the top of the breeding pyramid indicates a favourable MRSA situation in the Swedish pig population. MRSA: methicillin-resistant ; LA-MRSA: livestock-associated MRSA; CC: clonal complex.
耐甲氧西林金黄色葡萄球菌（LA-MRSA）已在许多国家的猪群中出现。猪群中的耐甲氧西林金黄色葡萄球菌构成了一个传染源，存在传染给与猪密切接触的人类的风险。种猪群顶层若无耐甲氧西林金黄色葡萄球菌，将防止其传播至其他猪群。本研究的目的是调查瑞典核心群和扩繁群猪场中耐甲氧西林金黄色葡萄球菌的发生情况。对2011年（共53个）和2014年（共39个）瑞典所有的核心群和扩繁群猪场进行了耐甲氧西林金黄色葡萄球菌采样。2011年和2014年均未检测到耐甲氧西林金黄色葡萄球菌。种猪群顶层未检测到耐甲氧西林金黄色葡萄球菌表明瑞典猪群的耐甲氧西林金黄色葡萄球菌情况良好。MRSA：耐甲氧西林；LA-MRSA：家畜相关耐甲氧西林金黄色葡萄球菌；CC：克隆复合体
