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 http://aem.asm.org/ Downloaded from
