A gram-negative harmful bacterium involved in cold water vibriosis of farmed salmonid fish and other fishes.
Vibrio salmonicida has been isolated from salmon wherein infection distributed to different organs as well as in bloods without an initial period of colonization of the host. It is also found in the intestines and it is a dominating bacteria in gut microbiota which cause pathogen to the water when it discharge outside. It reveals proliferation through blood during infection while the intestine acts as reservoir for transmission and survival.
Vibrio salmonicida is highly dependent in motility in order to access to the fish host and after invasion motility is no longer needed for virulence yet the absence of normal flagellation delayed the disease development.
Vibrio salmonicida is a causative agent that kills and infects salmon and other fish wherein if infected the fish becomes not edible. It is implicated in hemorrhagic septicemia in fishes manifested with the bleeding around the abdomen as well as in swim bladder, abdominal tract and posterior gastrointestinal tract.
