An efficient two-step recombination method for markerless gene deletion and insertion that can be used for repetitive genetic modification in Yersinia pestis was developed. The method combines lambda Red recombination and counterselective screening (sacB gene) and can be used for genetic modification of Y. pestis to construct live attenuated vaccines.
开发了一种高效的两步重组方法,用于无标记基因缺失和插入,可用于鼠疫耶尔森菌的重复基因修饰。该方法结合了λ Red重组和反选择筛选(sacB基因),可用于鼠疫耶尔森菌的基因修饰以构建减毒活疫苗。
