Development radiomodificating of mutants of microorganisms for the prevention and treatment of radiation injuries of animals

Stable radioresistant bacteria surviving at doses of 4 (E.coli «R10») and 2,4 kGy (B.bifidum «R6») were obtained by exposure to consistently increasing doses of gamma radiation. In contrast to the original microorganisms, radioresistant bacteria had a higher content of DNA, superoxide dismutase enzymes, catalase, glutathione peroxydaze, amino acids glycine, serine, cysteine. Made of radiorai-stetnih strains of drugs, serological answered the requirements, the area given radiation properties, protected 60-80 % lethal obtained the animals to 11,5 to 17,5 days increased the average life expectancy of dead animals versus 6.9 days in the control group exposure.
