Abstract

The generation in vivo of plasmids deleted at specific sites in strains of Klebsiella pneumoniae containing R plasmids, by treatment with high concentrations of acridine orange (1.2 mg/ml) at 42 degrees C are reported. These deletions seem to be site specific because loss of specific restriction fragments after digestion with restriction enzymes was demonstrated.

摘要

据报道,在42℃下用高浓度吖啶橙(1.2mg/ml)处理含有R质粒的肺炎克雷伯菌菌株,可在体内产生特定位点缺失的质粒。这些缺失似乎具有位点特异性,因为用限制性内切酶消化后特定限制性片段的丢失得到了证实。
