Streptococcus faecalis strains DS-5 and Streptococcus pyogenes strain AC-1 both have a 17 million dalton plasmid that determines resistance to erythromycin, lincomycin, and vernamycin B(alpha). The results of deoxyribonucleic acid-deoxyribonucleic acid hybridization experiments indicate that the two plasmids are about 95% homologous. It was also shown that erythromycin resistance is inducible in AC-1 and constitutive in DS-5.
粪肠球菌菌株DS - 5和化脓性链球菌菌株AC - 1都有一个1700万道尔顿的质粒,该质粒决定了对红霉素、林可霉素和维纳霉素B(α)的抗性。脱氧核糖核酸-脱氧核糖核酸杂交实验结果表明,这两种质粒约95%同源。还表明,红霉素抗性在AC - 1中是可诱导的,而在DS - 5中是组成型的。
