We investigated an outbreak of enterotoxigenic (ETEC) O159:H20 associated with the consumption of a tossed-noodle dish in a high school in 2016. Thirty-three ETEC strains isolated from clinical and food samples were genetically indistinguishable. The outbreak strains were resistant to third-generation cephalosporins and harbored a gene on a 97-kb self-transferable IncK plasmid. This is the first outbreak caused by CTX-M-15-producing ETEC strains.
我们调查了 2016 年一起与食用高中拌面条有关的肠产毒性(ETEC)O159:H20 暴发事件。从临床和食品样本中分离出的 33 株 ETEC 菌株在基因上无法区分。暴发菌株对第三代头孢菌素具有耐药性,并在一个 97kb 可自我转移的 IncK 质粒上携带一个 基因。这是首次由产 CTX-M-15 的 ETEC 菌株引起的暴发事件。
