Phylum Proteobacteria, Class Gammaproteobacteria, Order Vibrionales, Family Vibrionaceae, Genus Vibrio, Vibrio lentus Macian,
Ludwig, Aznar, Grimont, Schleifer, Garay and Pujalte, 2003.
Hystorical synonym: Phenon 2 Ortigosa et al.,1994.
Gram-negative rods, 1.5-3 x 0.8-1 µm, motile by one polar flagellum.
Colonies on Marine agar 2216 Difco are round, nonpigmented, opaque, not
swarming, 0.2-1.0 mm in diameter after 24-72 hours incubation at 22 ºC. Not
luminescent. Strains form green colonies on TCBS agar.
Can grow in nutrient broth with: 1 to 6% NaCl. No gowth in 0% NaCl. Growth
temperature 4 to 30 ºC. No growth at 37 ºC.
The type strain (4OM4T) was isolated from oysters from the Mediterranean coast of Valencia (Spain). Other strains were isolated from
common octopus (Octopus vulgaris) in Spain.
Resistant to O/129 vibriostatic agent.
Can cause circular lesions on the tentacles on the mantle and head in octopus. Proved by experimental infection.
