Abstract excerpt
Temperature-sensitive (TS) mutants of Salmonella typhi were isolated following mutagenesis with nitrosoguanidine and two cycles of enrichment with penicillin and D-cycloserine. Several of the TS mutants were characterized with respect to growth profiles at permissive (29 degrees C) and non-permissive (36 degrees C) temperatures, reversion rates, and the potential for inducing protection against challenge in an...
