In January 2017, CDC identified a cluster of Salmonella enterica serotype Newport infections with isolates sharing an indistinguishable pulsed-field gel electrophoresis (PFGE) pattern, JJPX01.0010 (pattern 10), through PulseNet, the national molecular subtyping network for foodborne disease surveillance. This report summarizes the investigation by CDC, state and local health and agriculture departments, and the U.S. Department of Agriculture's Food Safety and Inspection Service (USDA-FSIS) and discusses the possible role of dairy cows as a reservoir for strains of Salmonella that persistently cause human illness. This investigation combined epidemiologic and whole genome sequencing (WGS) data to link the outbreak to contaminated ground beef; dairy cows were hypothesized to be the ultimate source of Salmonella contamination.
2017年1月，美国疾病控制与预防中心（CDC）通过食源性疾病监测的国家分子分型网络PulseNet，发现了一群肠炎沙门氏菌新港血清型感染病例，分离出的菌株具有无法区分的脉冲场凝胶电泳（PFGE）图谱JJPX01.0010（图谱10）。本报告总结了美国疾病控制与预防中心、州和地方卫生与农业部门以及美国农业部食品安全检验局（USDA-FSIS）的调查情况，并讨论了奶牛作为持续导致人类疾病的沙门氏菌菌株宿主的可能作用。这项调查结合了流行病学和全基因组测序（WGS）数据，将此次疫情与受污染的碎牛肉联系起来；据推测，奶牛是沙门氏菌污染的最终源头。
