Vibrio cholerae can shift to a "rugose" colonial morphology associated with expression of an amorphous exopolysaccharide that promotes cell aggregation. Flow cytometric studies indicated that up to 3% of particles in rugose cultures represented aggregates of >5 bacterial cells. Rugose variants of our test strains displayed resistance to killing by chlorine… CONTINUE READING
