What does vibrio mean?
Vibrio is a technical biological term for a member of a group of bacteria that are usually curved or comma-shaped. The bacteria are found especially in water and marine environments, and many are harmless members of ordinary ecosystems. Others are pathogenic: Vibrio cholerae causes cholera, while other species can lead to wound infections or illnesses associated with eating contaminated seafood. In scientific writing, lowercase vibrio commonly refers to an individual bacterium, whereas capitalized Vibrio identifies the genus as a whole; the plural is vibrios. The word is useful because it distinguishes a distinctive bacterial form and recalls the close relationship between this group of organisms and some major diseases. Although it may sound like vibrato, a vibrio is a bacterium rather than a musical effect.
