Abstract

Intact cells of actinomycin-permeable mutants of Escherichia coli could be infected with urea-disrupted phage T4 (designated as T4pi). The parental strains and the revertants, which are impermeable to actinomycin, were not susceptible to T4pi unless they had been treated with agents which altered their permeability. The permeable mutants developed competence for pi infection during the growth cycle; cells in the early stationary phase produced 10- to 100-fold more plaques on plating with T4pi than did exponentially growing cells. Colistin (polymyxin E) was effective in converting noncompetent cells of either permeable or nonpermeable strains to the competent state. Treatment with lysozyme resulted in a considerable increase in susceptibility to T4pi of permeable mutants but not of nonpermeable cells. It appears that development of competence for pi infection is mainly due to alterations in the permeability barriers of the cell.

摘要

大肠杆菌放线菌素通透突变体的完整细胞能够被尿素裂解的噬菌体T4（称为T4pi）感染。亲本菌株及对放线菌素不通透的回复突变体对T4pi不敏感，除非它们经过改变其通透性的试剂处理。通透突变体在生长周期中形成了对pi感染的感受态；处于早期稳定期的细胞在用T4pi铺板时产生的噬菌斑比指数生长期的细胞多10到100倍。黏菌素（多黏菌素E）可有效地将通透或不通透菌株的无感受态细胞转变为感受态。用溶菌酶处理可使通透突变体对T4pi的敏感性显著增加，但对不通透细胞则无此作用。看来对pi感染感受态的形成主要是由于细胞通透性屏障的改变。
