Characterization and distribution of the cell-bound haemagglutinins produced by Vibrio cholerae.

ABSTRACT

The two biotypes of Vibrio cholerae were found to produce two distinct cell-bound haemagglutinins (HAs). El Tor vibrios, most of their nonmotile mutants and nonpathogenic El Tor strains produced a mannose-sensitive cell-bound HA constitutively under all growth conditions examined. Some classical vibrios, their nonmotile mutants and antigenically rough mutants of classical strains produced a fucose-sensitive cell-bound HA continually. Other classical vibrios produced neither cell-bound HA nor a fucose-sensitive cell-bound HA transiently.
