Pseudomonas aeruginosa is an opportunistic bacterium that is frequently found in patients with cystic fibrosis, burn wounds and various immuno-compromised conditions. The bacterium is known to produce various virulence factors through group communication behaviors known as quorum sensing. Here we report that autolysis or self-killing is a socially beneficial behavior of the bacteria and compare the wild-type and a mutant strain (deficient in one of the transcriptional activators of quorum sensing). Some of the group behaviors that are compared in the study are the ability of the bacteria to undergo programmed cell death or autolysis, the ability of the bacteria to produce the blue-green pigment pyocyanin which is toxic to many Gram-positive bacteria and animal cells, and the ability of the bacteria to form biofilms.
