ABSTRACT An extracellular exopolysaccharide (slime) is produced byVibrio cholerae O139 MO10 in response to nutrient starvation. The presence of this slime layer on the cell surface and its subsequent release have been shown to be associated with biofilm formation and the change from a normal smooth colony morphology to a rugose one. An immunoelectron microscopic examination demonstrated that there is an epitope common to the exopolysaccharide antigen of V. cholerae O1 and that of O139 MO10.

The rugose form ofVibrio cholerae O139 MO10, a nutrient-starved strain, is associated with biofilm formation and the release of an extracellular exopolysaccharide, which is common to both V. cholerae O1 and O139 MO

Isolation and Characterization of Rugose Form of Vibrio cholerae O139 Strain MO10

Key Takeaway: The rugose form ofVibrio cholerae O139 MO10, a nutrient-starved strain, is associated with biofilm formation and the release of an extracellular exopolysaccharide, which is common to both V. cholerae O1 and O139 MO
