Presence of quorum-sensing-mediated gene regulation in pathogenic ice-nucleation-active (INA) bacteria

Sammanfattning

Nine out of a total of 20 pathogenic ice-nucleation-active bacteria, with different levels of inducible INA, were tested and found positive for their ability to synthesize quorum-sensing (QS) signals. The bacteria were isolated from willow plants and belonged to the genera Bacillus, Erwinia, Pseudomonas and Sphingomonas. As reporter bacteria, to detect the homoserine lactone (HSL) autoinducer, Agrobacterium tumefaciens, Chromobacterium violaceum, Pseudomonas aeroginosa, Aeromonas hydrophila and Vibrio fischeri strains were used. We thus provide evidence that pathogenic ice-nucleation bacteria with inducible INA produce QS signals that in other bacteria have been shown to be in the control of genes of importance for pathogenicity
