Autolysis in Vibrio tubiashii and Vibrio coralliilyticus.
Vibrio tubiashii has been linked to disease outbreaks in molluscan species, including oysters, geoducks, and clams, and shellfish hatcheries in the Pacific Northwest have been plagued by intermittent vibriosis outbreaks since 2006. Like V. tubiashii, Vibrio coralliilyticus has recently been described as an oyster pathogen in addition to its role in coral disease. Here, we describe an autolysis phenotype in V. tubiashii and its close relative V. coralliilyticus and characterize the effects of environmental conditions on this phenotype. We also explored whether the survivors of autolysis were resistant to the phenotype and if material from the autolysed culture would either regrow or have a population of viable cells. Ultimately, this work contributes to the larger understanding of bacterial population dynamics as it relates to aquaculture pathogens.
