Gram-negative, curved rods, motile by a large single polar flagellum when grown in
liquid medium. Swarming on complex media. Lateral flagella produced when grown
on solid medium. Colonies after 48 h of growth are circular, smooth, & unpigmented.
Can grow in nutrient broth with: 1%NaCl, 6% NaCl. No growth in 0% NaCl, 8% NaCl,
10% NaCl & 12% NaCl. Growth temperature 4 ºC - 30 ºC. Optimal growth at 20 ºC.
Facultatively anaerobe.
Isolated from scallop (Pecten maximus) larvae.
Isolated from moribund scallop larvae during outbreaks of disease in a French hatchery. Vibrio pectenicida seems to be a specific
pathogen only for Jacques scallops (Pecten maximus), because, experimentally, the larvae of oysters (Crassostrea gigas) are not
sensitive. Can synthesize an endotoxin, a thermostable cilliostatic toxin, and one or more toxins capable of altering the hemocytes.
