Interpretive Summary: Shellfish hatcheries have experienced high larval oyster mortalities from a naturally-occurring marine bacterium known as Vibrio coralliilyticus. Some strains of V. coralliilyticus appear more disruptive to hatchery operations than others, including the strain known as RE22. We sequenced the DNA of the entire RE22 genome and added it to GenBank for public access. This information is expected to lead to the identification of additional genes responsible for larval shellfish mortalities.

Technical Abstract: Vibrio coralliilyticus RE22 is an indigenous marine pathogen that infects larval bivalve shellfish. This strain is particularly problematic in oyster hatcheries where it causes high larval mortalities. It contains two circular chromosomes and one megaplasmid. Annotation reveals multiple genes which may encode important virulence factors.
