What are the characteristics of vibrio bacteria?

Introduction. Members of the genus Vibrio are defined as Gram-negative, asporogenous rods that are straight or have a single, rigid curve. They are motile; most have a single polar flagellum, when grown in liquid medium. Most produce oxidase and catalase, and ferment glucose without producing gas (7).

What shape does a Vibrio cell look like?

Vibrios are microbiologically characterized as gram-negative, highly motile, facultative anaerobes (not requiring oxygen), with one to three whiplike flagella at one end. Their cells are curved rods 0.5 μ m (micrometre; 1 μ m = 10 -6 metre) across and 1.5 to 3.0 μ m long, single or strung together in S-shapes or spirals .
