Summary. Repeated heat treatment and subculture increased the heat resistance of one strain of Salmonella typhimurium with no apparent increase in pathogenicity, or significant change in common biochemical characters. Cycling to γ radiation produced similar results. Re‐cycled strains contained extremely low proportions of the smooth colonies required for serological and phage typing.
