Gram-negative, rod-shaped cells, 1.2-1.5 x 0.8 µm, motile by a single polar, sheathed
flagellum. Nonsporulated.
Can grow in nutrient broth with: 1% to 7% NaCl, no growth in 0% or 8% NaCl.
Colonies on marine agar 2216 Difco are cream-coloured, with smooth edges after
48 hours at 30 ºC. Colonies are yellow on TCBS agar. Nonluminescent.
Isolated from diseased coral of the species Pocillopora damicornis in the Indian Ocean, Red Sea and from larvae of oysters in the
Atlantic Ocean
Susceptible to vibriostatic agent O/129. Resistant to kanamycin, ampicillin and penicillin.
Pathogenic to the coral P. damicornis (tissue lysis of the coral).
