Identification of quorum-sensing signal molecules and the LuxRI homologs in fish pathogen Edwardsiella tarda.

Edwardsiella tarda is a gram-negative bacterium that causes septicaemia in fish and serious damage to the aquaculture industry. The virulence factors of this pathogen and control mechanisms of the expression of virulence genes have not yet been clearly elucidated. A number of gram-negative pathogenic bacteria have a quorum-sensing system. These bacteria… CONTINUE READING
