We have identified IS100 sequences in a specific subset of Yersinia pseudotuberculosis isolates that were also sensitive to the Y. pestis-produced bacteriocin, pesticin. In contrast, Y. pseudotuberculosis strains which did not contain IS100 sequences were not sensitive to pesticin. We propose that IS100 serves as a molecular marker that identifies a subset of Y. pseudotuberculosis isolates that have a particularly close evolutionary and/or ecological relationship with Y. pestis.
我们在假结核耶尔森菌分离株的一个特定亚群中鉴定出了IS100序列,这些分离株对鼠疫耶尔森菌产生的细菌素——鼠疫菌素也敏感。相比之下,不含IS100序列的假结核耶尔森菌菌株对鼠疫菌素不敏感。我们提出,IS100可作为一种分子标记,用于识别与鼠疫耶尔森菌具有特别密切进化和/或生态关系的假结核耶尔森菌分离株亚群。
