title: [Genetic analysis of Vibrio cholerae chromosomal regions containing the tox-2 mutation, affecting production of cholera toxin].
abstract: Conjugational-mating experiments showed mrh genes coding for the synthesis of mannose and fucose resistant hemagglutinin/adhesin and vibrio motility gene mot to be localized in the chromosome of V. cholerae Dacca strain 35 close to tox-2 mutation providing a high level of toxin production and rfb locus which controls 01 antigen synthesis. The results indicate the presence of a block of virulence genes within ura-pur chromosomal region of V. cholerae.
