title: [Possibilities of using Salmonella cya, crp mutants as vectors of an oral recombinant vaccine].
abstract: The Salmonella typhimurium B-2/1 double mutant with cya and crp mutations was obtained by a recombination process. The mutant exhibited a low virulence and inability to utilize citrate. In terms of these properties, the mutant differs from the wild-type strain. The mutant is able to persist in the body of mice, cattle, and monkeys, provoking the immune response to its oral administration.
