Vibrio campbellii

Vibrio campbellii is a Gram-negative, curved rod-shaped, marine bacterium closely related to its sister species, Vibrio harveyi. It is an emerging pathogen in aquatic organisms. Quorum sensing allows the bacterium to communicate with autoinducers, a chemical signaling molecule that is secreted. Some strains of V. campellii are known to be not luminescent; these strains are thought to be less virulent than the luminescent strains.Bioluminescence in bacteria is due to the reaction:
