Abstract
Photobacterium damselae subsp. damselae is a ubiquitous marine bacterium and opportunistic pathogen of compromised hosts of diverse taxa. In contrast, its sister subspecies P. damselae subsp. piscicida ( Pdp ) is highly virulent in fish. Pdp has evolved from a single subclade of Pdd through gene loss and acquisition.
