Cross-resistance between bacteriophages and colicins was studied using collections of bacteriophage- and colicin-resistant mutants of Escherichia coli K-12. No new examples were found of highly specific one-to-one cross-resistance of the type suggestive of common receptors. However, several groups of mutants showed tolerance to colicins and resistance to bacteriophages. Mutants known to be very defective in lipopolysaccharides composition were found to commonly show tolerance to certain colicins in addition to their bacteriophage resistance. Another group of mutants showed varying patterns of resistance to colicins E2, E3, K, L, A, S4, N, and X and bacteriophages E4, K2, K20, K21, K29, and H+. However, many bacteriophage-resistant mutants were fully colicin sensitive, and most colicin-resistant mutants were fully sensitive to bacteriophages.
利用大肠杆菌K-12的噬菌体抗性突变体和大肠杆菌素抗性突变体库,研究了噬菌体与大肠杆菌素之间的交叉抗性。未发现新的高度特异性一对一交叉抗性实例,这类实例表明存在共同受体。然而,几组突变体表现出对大肠杆菌素的耐受性和对噬菌体的抗性。已知在脂多糖组成方面存在严重缺陷的突变体,除了具有噬菌体抗性外,通常还对某些大肠杆菌素表现出耐受性。另一组突变体对大肠杆菌素E2、E3、K、L、A、S4、N和X以及噬菌体E4、K2、K20、K21、K29和H+表现出不同的抗性模式。然而,许多噬菌体抗性突变体对大肠杆菌素完全敏感,大多数大肠杆菌素抗性突变体对噬菌体也完全敏感。
