What shape are Vibrio bacteria? Vibrios are highly motile, gram-negative, curved or comma-shaped rods with a single polar flagellum. Of the vibrios that are clinically significant to humans, Vibrio cholerae O group 1, the agent of cholera, is the most important.
Can you survive Vibrio?
Most people with a mild case of vibriosis recover after about 3 days with no lasting effects. However, people with a Vibrio vulnificus infection can get seriously ill and need intensive care or limb amputation. About 1 in 5 people with this type of infection die, sometimes within a day or two of becoming ill.

What disease does Vibrio vulnificus cause?
Some Vibrio vulnificus infections lead to necrotizing fasciitis, a severe infection in which the flesh around an open wound dies. Some media reports call this kind of infection “flesh-eating bacteria,” even though necrotizing fasciitis can be caused by more than one type of bacteria.
