Abstract

or Group A (GAS), is a major human pathogen for which genetic manipulation remains an ongoing challenge. We created a new temperature-sensitive plasmid pBFK expressing spectinomycin resistance adapted to homologous recombination procedure to perform a complete gene deletion in GAS. Herein the mutagenesis strategy with pBFK was performed in a highly virulent GAS genotype.

摘要

A组链球菌(GAS)是一种主要的人类病原体,对其进行基因操作仍是一项持续的挑战。我们构建了一种新的表达壮观霉素抗性的温度敏感质粒pBFK,该质粒适用于同源重组程序,以在A组链球菌中进行完整的基因缺失。本文中,采用pBFK的诱变策略在一种高毒力的A组链球菌基因型中进行。
