Mostow P, Richardson K
Abstract excerpt
The species Vibrio cholerae contains within it two biotypes, classical and El Tor, both of which are motile. Phenotypic expression of motility was unaffected by type of growth medium, salt concentration, pH, or temperature of incubation. However, seven strains of classical V. cholerae produced spontaneous nonmotile mutants at an unusually high frequency (ca. 10(-4)), while no mutants were detected for all three...
