Evidence for horizontal gene transfer, gene duplication and genetic variation as driving forces of the diversity of haemolytic phenotypes in Photobacterium damselae subsp. damselae.

Abstract excerpt

Photobacterium damselae subsp. damselae, a marine bacterium that causes infections in marine animals and in humans, produces up to three different haemolysins involved in virulence, which include the pPHDD1 plasmid-encoded damselysin (Dly) and HlyApl , and the chromosome-encoded HlyAch . We screened 45 isolates from different origins, and found a correlation between their haemolytic phenotypes and the...
