A colistin-resistant mutant of Klebsiella pneumoniae served well as a donor but not as a recipient in conjugation. A nearly 1,000-fold difference between colistin-susceptible and colistin-resistant forms of this strain was observed by using donors of plasmids of four incompatibility groups. Recipient efficiency was not restored by filter matings.
肺炎克雷伯菌的耐黏菌素突变体在接合中作为供体表现良好,但作为受体则不然。通过使用四个不相容群质粒的供体,观察到该菌株的黏菌素敏感型和耐黏菌素型之间存在近1000倍的差异。滤膜交配并未恢复受体效率。
