Comparative assessment of Vibrio virulence in marine fish larvae
Vibrionaceae infections are a major obstacle for marine larviculture; however, little is known about virulence differences of Vibrio strains. The virulence of Vibrio strains, mostly isolated from vibriosis outbreaks in farmed fish, was tested in larval challenge trials with cod (Gadus morhua), turbo...

Vibrionaceae infections are a major obstacle for marine larviculture; however, little is known about virulence differences of Vibrio strains.

Some Vibrio strains were pathogenic in all of the larva species, while some caused disease only in one of the species.
