Present in marine environments such as estuaries, brackish ponds, or coastal areas, V. vulnificus is related to V. cholerae, the causative agent of cholera. At least one strain of V. vulnificus is bioluminescent. Infection with V. vulnificus leads to rapidly expanding cellulitis or sepsis. V. vulnificus is also a source of foodborne illness. It was first isolated as a source of disease in 1976. Signs and symptoms Vibrio vulnificus is an extremely virulent bacterium that can cause three types of infections:
