Old synonym: Vibrio sp. P1.
Gram-negative rods, 1.0 to 1.5 by 0.5 µm) motile by a single polar flagellum.  Not
swarming on complex media. Nonspore-forming. No luminescence.
Grows at 4-22 ºC with optimum growth at 22 ºC. Grows on marine agar and tryptone
soya agar containing 2% NaCl. Grows in media supplemented with 1 to 3% (wt/vol)
NaCl but not higher than 5% NaCl. No growth in the absence of NaCl. Facultatively
anaerobic. Colonies are circular, translucent, nonpigmented on marine agar and
green on TCBS agar (thiosulfate-citrate-bile salts-sucrose agar).
Isolated from wild and cultured clams.
The type strain was isolated from cultured manila clam (Tapes philippinarum), Landeda, France. Causes brown ring disease in
several species of wild and cultured clams.
