Abstract
Genomic characterization of an Escherichia coli O157:H7 strain linked to leafy greens-associated outbreaks dates its emergence to late 2015. One clade has notable accessory genomic content and a previously described mutation putatively associated with increased arsenic tolerance. This strain is a reoccurring, emerging, or persistent strain causing illness over an extended period.
摘要
一株与叶类蔬菜相关暴发有关的大肠杆菌 O157:H7 菌株的基因组特征表明其起源于 2015 年末。一个分支具有显著的附属基因组内容，以及先前描述的可能与砷耐量增加相关的突变。该菌株是一种反复发作、新出现或持续存在的菌株，在较长时间内引起疾病。
