Abstract
Salmonella typhimurium
LT-2 was compared with radioresistant (B/r) and radiosensitive (B
s
−
2
) strains of
Escherichia coli
in respect to the survival, deoxyribonucleic acid (DNA) breakdown, and DNA synthesis after X irradiation. It is shown that
S. typhimurium
LT-2 is about four times more sensitive than
E. coli
B/r but less sensitive than B
s
−

. The DNA breakdown is in
S. typhimurium
LT-2 lower than the postirradiation breakdown of DNA in both
E. coli
strains and DNA synthesis proceeds in this bacterium in spite of a much lower survival, as in the radioresistant
E. coli
B/r.
