Eleven Salmonella enterica serovar Bovismorbificans isolates obtained from the U.S. District of Columbia during a 2011 hummus-associated foodborne outbreak were compared to 12 non-outbreak isolates. All isolates from the outbreak demonstrated a single PFGE pattern that was distinctly different from other isolates of S. Bovismorbificans as recorded in the PulseNet Database. Results from molecular analyses of the hummus-associated S. Bovismorbificans isolates indicate that the isolates from the outbreak were unique and have acquired an 80-90 kb plasmid. The impact of this study is that the information gained will add and expand our knowledge of diversity of the S. Bovismorbificans serovar.
从美国哥伦比亚特区在 2011 年与胡姆斯相关的食源性疾病暴发中获得的 11 株肠炎沙门氏菌牛型亚种分离株与 12 株非暴发分离株进行了比较。暴发中的所有分离株均表现出一种独特的 PFGE 模式，与脉冲网数据库中记录的其他肠炎沙门氏菌牛型亚种分离株明显不同。与胡姆斯相关的肠炎沙门氏菌牛型亚种分离株的分子分析结果表明，暴发中的分离株是独特的，并获得了一个 80-90 kb 的质粒。这项研究的意义在于，所获得的信息将增加和扩展我们对肠炎沙门氏菌牛型亚种多样性的认识。
