Plasmids R26 (Inc P) and R55-1 (Inc C) specify inducible nonenzymatic resistance to chloramphenicol. Escherichia coli K-12 strains harboring these plasmids encoded low-level resistance to thiamphenicol analogs Sch 25298 and Sch 25393 but failed to specify resistance to the fluorinated chloramphenicol analog Sch 24893. The analogs were efficient inducers of high-level chloramphenicol resistance.
质粒R26(Inc P)和R55 - 1(Inc C)可产生对氯霉素的诱导型非酶抗性。携带这些质粒的大肠杆菌K - 12菌株对甲砜霉素类似物Sch 25298和Sch 25393编码低水平抗性,但对氟化氯霉素类似物Sch 24893不产生抗性。这些类似物是高水平氯霉素抗性的有效诱导剂。
