Abstract: | Vibrio parahaemolyticus, the flagellated nonswarming marine bacteria were induced to swarm on solid media under three different conditions: growth at 20–26°C on medium containing 1% NaCl, growth on a medium in a sealed Petridish and growth on H2O2-treated medium. The morphological transformations observed in cells during swarming of V. parahaemolyticus are similar to those found jor the naturally swarming Vibrio alginolyticus. The mechanism of swarming in both species involves massive formation of peritrichous flagella and a negative chemotactive response to metabolic byproducts. |
