title: Isolation of a non-adhesive mutant of Vibrio cholerae and chromosomal localization of the gene controlling mannose-sensitive adherence.
abstract: A mutant (CD11) of Vibrio cholerae was isolated after exposure of a wild-type pathogenic strain (KB207) to N-methyl-N'-nitro-N-nitrosoguanidine. Although the mutant was motile and chemotactic, it adhered poorly to rabbit intestinal mucosa. Pretreatment of vibrios with 10 mg D-mannose ml-1 and of intestinal mucosa with 100 mmol sodium metaperiodate inhibited adherence of KB207 but not of CD11. The gene (ams) controlling mannose-sensitive adherence was mapped on the bacterial chromosome closely linked to the pur locus.
