[Transfer of S. typhimurium strains with mutation to a noncultured state, disrupting synthesis of purine bases].

Effects of mutations impairing the synthesis of purine nucleotides on the process of S. typhimurium cells transfer into an unculturable state (US) have been studied. The presence of guaA- mutation in the cells was found to lead to a sooner transfer to US in comparison with the cells of reference strain. The presence of purE- mutation does not tell on the rate of mutant cells transfer in US.
