We conducted a surveillance study to investigate the epidemiology of Staphylococcus aureus infections in Iowa, using a convenience sample. Diagnostic laboratories submitted 20 S. aureus isolates per month for a 20-month period between 2011 and 2013. Of the 2226 isolates analyzed, 73.6% were methicillin-resistant S. aureus (MRSA) and 26.4% were methicillin-susceptible S. aureus (MSSA). S. aureus infections in 25 patients (1%) were caused by ST398- and ST9-associated strain types, and appeared to be a common occurrence in areas of the state with the highest numbers of hogs and hog farms. Twenty nine (5.1%) of MSSA isolates and 10 (40.0%) livestock-associated strains were multi-drug resistant.
我们进行了一项监测研究,以便利抽样的方式调查爱荷华州金黄色葡萄球菌感染的流行病学情况。在2011年至2013年的20个月期间,诊断实验室每月提交20株金黄色葡萄球菌分离株。在分析的2226株分离株中,73.6%为耐甲氧西林金黄色葡萄球菌(MRSA),26.4%为甲氧西林敏感金黄色葡萄球菌(MSSA)。25名患者(1%)的金黄色葡萄球菌感染由ST398和ST9相关菌株类型引起,在该州生猪和养猪场数量最多的地区似乎很常见。29株(5.1%)MSSA分离株和10株(40.0%)与家畜相关的菌株对多种药物耐药。
