The major Vibrio cholerae autoinducer and its role in virulence factor production

The major Vibrio cholerae autoinducer and its role in virulence factor production In a process called quorum sensing, certain bacteria can communicate with each other using chemical signalling molecules, allowing them to synchronize gene expression so that they act virtually as multicellular organisms. The cholera pathogen Vibrio cholerae uses quorum sensing to control virulence and to organize the biofilms that contribute to the difficulties of treating the infection. Now the major V. cholerae quorum-sensing signalling molecule, an autoinducer called CAI-1, has been identified and characterized as (S)-3-hydroxytridecan-4-one, a molecule new to biology. Providing CAI-1 to the bacterium terminates the production of factors required for pathogenicity, suggesting a possible new treatment for this major pathogen. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Nature Springer Journals

Abstract

In a process called quorum sensing, certain bacteria can communicate with each other using chemical signalling molecules, allowing them to synchronize gene expression so that they act virtually as multicellular organisms. The cholera pathogen Vibrio cholerae uses quorum sensing to control virulence and to organize the biofilms that contribute to the difficulties of treating the infection. Now the major V. cholerae quorum-sensing signalling molecule, an autoinducer called CAI-1, has been identified and characterized as (S)-3-hydroxytridecan-4-one, a molecule new to biology. Providing CAI-1 to the bacterium terminates the production of factors required for pathogenicity, suggesting a possible new treatment for this major pathogen.
