Gram-negative, motile, short rods (0.5 x 1.5 µm). Motile by a single polar flagellum in
liquid medium. Does not swarm on solid media, but lateral short-wavelength flagella
may be produced. Non-spore-forming. No pigments are produced. No luminescence.
Colonies are smooth, circular, off-white and sometimes mucoid on Marine agar;
yellow on TCBS agar.

The optimal NaCl concentration for growth is 1 to 6% and it does not grow at higher
than 8% or below 0.3% NaCl. Growth temperature 35 ºC, no growth at 4 ºC.
Facultatively anaerobe.
Grows on simple mineral media on a variety of organic carbon sources, including
glycine, mannose, and galactose but not D-sorbitol or y-aminobutyrate.

Isolated from larvae and juveniles of the hard clam (Mercenaris mercenaria), oyster spat (Crassostrea virginica) and adult oyster.
Causes disease in larvae and juveniles of bivalve mollusks. Pathogenic for oyster (Crassostrea virginica, Crassostrea gigas, & Ostrea
edulis) and clam (Mercenaris rnercenaria) larvae.
