Phylum Proteobacteria, Class Gammaproteobacteria, Order Vibrionales, Family Vibrionaceae, Genus Vibrio, Vibrio mimicus Davis,
Fanning, Madden, Steigerwalt, Bradford, Smith and Brenner 1982.
Historical synonym: “Vibrio cholerae sucrose negative” 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 or 40 ºC.
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.
