CDC is collaborating with the U.S. Department of Agriculture's Animal and Plant Health Inspection Service (USDA-APHIS) and state health departments to investigate an outbreak of human Salmonella Typhimurium infections with an indistinguishable pulsed-field gel electrophoresis pattern linked to contact with pet hedgehogs. This outbreak strain is historically rare, with only one to two cases reported via PulseNet (the national molecular subtyping network for foodborne disease surveillance) annually since 2002. Since 2011, an increasing number of cases have been detected. PulseNet identified 14 human isolates in 2011, 18 in 2012, and two in 2013.
疾病预防控制中心（CDC）正在与美国农业部动植物卫生检验局（USDA-APHIS）以及州卫生部门合作，调查一起人类沙门氏菌 Typhimurium 感染爆发事件，其脉冲场凝胶电泳模式无法区分，与接触宠物刺猬有关。这种爆发菌株在历史上较为罕见，自 2002 年以来，通过脉冲网络（全国食源性疾病监测的分子分型网络）每年仅报告一到两例。自 2011 年以来，已发现越来越多的病例。脉冲网络在 2011 年识别出 14 个人类分离株，2012 年识别出 18 个，2013 年识别出 2 个。
