Historical synonym: “Vibrio cholerae sucrose -” Davis et al. 1982.
Gram negative, curved rods, motile by means of a single polar flagellum. No swarming.
Can grow in nutrient broth with: 0% NaCl & 1% NaCl. Variable gowth in 6%NaCl.
No growth in 8% NaCl, 10% NaCl & 12% NaCl. Growth at 4 °C - 40 °C.
Is similar to Vibrio cholerae non-O1 in its ecology, distribution, and pathogenicity
Occurs in aquatic environments and some strains apparently cause diarrhea and human intestinal infections; occasionally causes
extraintestinal human infections. The type strain was isolated from a human ear culture.
Sensible to O/129 vibriostatic agent (10 & 150 µg).
Some strains apparently cause diarrhea and human intestinal infections; occasionally causes extraintestinal human infections.
Is similar to Vibrio cholerae non-O1 in its pathogenicity.
