The cell surfaces of several toxigenic and nontoxigenic environmental and clinical isolates of Vibrio cholerae non-Ol have been examined. The environmental strains, irrespective of toxigenicity, are significantly more resistant to antibiotics and detergents than are V. cholerae 01 strains. The clinical isolates of non-Ol vibrios are as sensitive to a wide variety of chemicals as the 01 vibrios. The environmental non-Ol strains are also less susceptible to lysis when treated with protein

In contrast to 01 vibrios, the environmental non-01 vibrios do not have exposed phospholipids in their outer membranes. These features of the cell surfaces of environmental non-Ol vibrios might have a role in the better survival of these organisms under environmental fluctuations. of the compound at which there was no visible growth was 3567 on May 5, 2020 by guest Downloaded from
