title: [Sensitivity of repair-defective mutants of the plague microbe to the action of physical and chemical agents].
abstract: By the character of the sensitivity of UV-irradiation, to N-methyl-N'-nitro-N-nitrosoguanidine, 5-bromuracil, mitomycin C, crystalviolet, and by the capacity to restore phage injuries the 1435-A and 1435-24 mutants were referred to the uvr-hcr-, 17 mutant--to the uvr-hcr+, and 35 mutant--to lon genotype. As a result of UV irradiation the experimental strains formed heteromorphic forms of bacteria, spindle-shaped, filamentous cells, were sensitive to the action of static electrical field of high frequency, this pointing to disturbance of cellular membranes structure in these mutants.
