In September 2015, PulseNet, the national molecular subtyping network for foodborne disease surveillance, identified a cluster of Listeria monocytogenes (Listeria) clinical isolates indistinguishable by two-enzyme pulsed-field gel electrophoresis (PFGE) pattern combination and highly related by whole-genome multilocus sequence typing (wgMLST). A case was defined as isolation of Listeria with the outbreak PFGE pattern and highly related by wgMLST with an isolation date on or after July 5, 2015, the isolate date of the earliest case in this cluster.
2015 年 9 月,用于食源性疾病监测的全国分子分型网络 PulseNet 通过两种酶脉冲场凝胶电泳(PFGE)模式组合鉴定出一组不可区分的李斯特菌(李斯特菌)临床分离株,这些分离株通过全基因组多位点序列分型(wgMLST)高度相关。病例定义为分离出具有暴发 PFGE 模式且通过 wgMLST 高度相关的李斯特菌,其分离日期为 2015 年 7 月 5 日或之后,这是该群集中最早的病例的分离日期。
