As an opportunistic pathogen worldwide, can cause food poisoning and human infections. This study investigated the sequence typing, the penicillin (blaZ) and methicillin (mec) resistance profiles of from food samples and food poisoning outbreaks in Shijiazhuang City, and the staphylococcal enterotoxin (SE) types of the isolates from food poisoning. A total of 138 foodborne isolates were distributed into 8 clonal complexes (CCs) and 12 singletons. CC1, CC5, CC8, CC15, CC97, CC59, CC398, CC88, and CC7 were the predominant CCs of foodborne isolates. Moreover, CC59, CC15, and CC5 were the most prevalent CCs in food poisoning outbreaks. SEE was the most commonly detected SE in food poisoning isolates. One hundred thirty-three isolates harbored the penicillin-resistant gene , and nine isolates carried the gene. The present study further explained the relationship between and foods and food poisoning and indicated the potential risk of infection.
作为一种全球范围内的机会致病菌，可引起食物中毒和人类感染。本研究调查了石家庄市食品样本和食物中毒暴发中分离出的金黄色葡萄球菌的序列分型、青霉素（blaZ）和甲氧西林（mec）耐药情况，以及食物中毒分离株的葡萄球菌肠毒素（SE）类型。共138株食源性金黄色葡萄球菌分离株被分为8个克隆复合体（CCs）和12个单克隆。CC1、CC5、CC8、CC15、CC97、CC59、CC398、CC88和CC7是食源性金黄色葡萄球菌分离株的主要CCs。此外，CC59、CC15和CC5是食物中毒暴发中最常见的CCs。SEE是食物中毒分离株中最常检测到的SE。133株金黄色葡萄球菌分离株携带青霉素耐药基因，9株携带mec基因。本研究进一步解释了金黄色葡萄球菌与食物及食物中毒之间的关系，并指出了金黄色葡萄球菌感染的潜在风险。
