Specific insertion and deletion of insertion sequence 1-like DNA element causes the reversible expression of the virulence capsular antigen Vi of Citrobacter freundii in Escherichia coli.
Citrobacter freundii strain WR7004 reversibly expresses the virulence capsular antigen Vi, whose production is controlled by two distinct chromosomal loci, viaA and viaB. The rate of oscillation between the Vi-producing (Vi+) state and the Vi-nonproducing (Vi-) state in strain WR7004 ranges from 2 X...
