Streptococcus mutans GS-5 was transformed to erythromycin resistance with streptococcal plasmid pVA736. Transformation frequencies were higher with plasmids reisolated from transformed GS-5 cells relative to plasmid originally derived from S. sanguis Challis.
变形链球菌GS-5用链球菌质粒pVA736转化为对红霉素耐药。相对于最初来源于血链球菌Challis的质粒,从转化的GS-5细胞中重新分离的质粒转化频率更高。
