Swarming behavior of and hemolysin BL secretion by Bacillus cereus.
An association between swarming and hemolysin BL secretion was observed in a collection of 42 Bacillus cereus isolates (P=0.029). The highest levels of toxin were detected in swarmers along with swarm cell differentiation (P=0.021), suggesting that swarming B. cereus strains may have a higher virulence potential than nonswarming strains.
