The presence of Methicillin-Resistant Staphylococcus aureus (MRSA) in pig farms has been widely reported, and the emergence of extended-spectrum β-lactamase-producing Enterobacteriaceae (ESBL-E) has been documented in several countries. However, data for Switzerland are very scarce. This study aimed to compare changes in the prevalence of MRSA in Swiss pig farms between 2008 and 2015 and make the first ever estimates of the presence of ESBL-E and carbapenemase producers in pigs and pig farm workers. Results showed that ESBL-E was present in both pigs and farm workers and that the proportion of farms with MRSA had increased fourfold in seven years (from 7% to 31%). Associations between antibiotic use and resistant bacteria carriage were shown.
耐甲氧西林金黄色葡萄球菌（MRSA）在养猪场中的存在已被广泛报道，并且在多个国家已经记录到产超广谱β-内酰胺酶的肠杆菌科（ESBL-E）的出现。然而，瑞士的数据非常稀缺。本研究旨在比较 2008 年至 2015 年瑞士养猪场中 MRSA 流行率的变化，并首次对猪和养猪场工人中产 ESBL-E 和碳青霉烯酶的情况进行估计。结果表明，ESBL-E 同时存在于猪和农场工人中，并且在七年中，MRSA 阳性农场的比例增加了四倍（从 7%增加到 31%）。研究还表明了抗生素使用与耐药菌携带之间的关联。
