What class of drugs is used to treat infections caused by Vibrio species?

Tetracyclines are effective in treating infections caused by Vibrio species, particularly Vibrio cholerae, which is responsible for cholera. This class of antibiotics works by inhibiting protein synthesis in bacteria, making it useful against a variety of gram-negative bacteria, including Vibrio. Tetracyclines have good tissue penetration and are often preferred for treating infections due to their efficacy and low resistance levels associated with Vibrio species.

Other classes such as fluoroquinolones and macrolides can also have activity against Vibrio, but tetracyclines are traditionally recommended for cholera treatment and have a history of use in this context. Cephalosporins may not be as effective against Vibrio compared to tetracyclines, making the latter the most appropriate choice for these infections.
