. ''V. alginolyticus'' was first identified as a pathogen of humans in 1973.Longo, Dan, et al. Harrison's Principles of Internal Medicine 18th edition. McGraw-Hill Professional, 2011. It occasionally causes eye, ear, and wound infections. It is a highly salt-tolerant species and can grow in salt concentrations of 10%. Most clinical isolates come from superinfected wounds that become contaminated at the beach. Tetracycline is typically an effective treatment. ''V. alginolyticus'' is rare cause of bacteremia in immunocompromised hosts.
