title: [Study of the sensitivity of a morphological mutant of S. typhimurium to irradiation].
abstract: Morphological Salmonella typhimurium LT2 WT--ED 143 mutant was similar by the character of the UV-sensitivity to the lon-mutants of Escherichia coli K-12. The paper treats of the data on the UV-sensitivity of the mutant and the initial strains at various growth phases, by the capacity to restore the irradiated P22 and Felix O bacteriophages and by the effect of various postradiational treatment on the irradiated strains. Data are presented on densitometry of the membrane proteins of the initial and the mutant strains, permitting to associate the unusual morphology, disturbed division and increased UV-sensitivity with the state of the membrane components of the bacterial cell.
