Urdaci, Marchand, Ageron, Arcos, Sesma and Grimont 1991.
Gram-negative, straight rods, 1-2 x 0.8-1 µm, motile by a single polar flagellum,
nonspore-forming. No lateral flagella on solid media. Not swarming on complex media.
Colonies on nutrient agar supplemented with 2% NaCl are 2 to 3 mm in diameter
after overnight incubation at 30 ºC, round, opaque, and nonpigmented. Not
luminescent; on TCBS agar are yellow.
Grow in nutrient broth with: 1% NaCl, 6% NaCl & 8% NaCl (variable). No growth in 0%
NaCl, 10% NaCl & 12% NaCl. Growth temperature 10ºC - 40ºC. No growth at 4ºC.
Isolated from sewage, irrigation water and river water in Spain. Sensible to O/129 vibriostatic agent (10 µg).
Unknown.
