Vibrio vulnificus is a Gram-negative bacterium that belongs to the Vibrionaceae family. It represents a deadly opportunistic human pathogen which grows in water with the proper temperature and salinity, and is mostly acquired from seafood eating or direct contact. In susceptible individuals, a traumatic infection could be fatal, causing severe wound infection and even septic shock, and may require amputation. Global warming plays an important role in the geographical area expanding of Vibrio disease. The pathogenesis of Vibrio vulnificus-associated sepsis is very complex, including iron intake, cell injury, and adhesion-related protein and virulence regulation. Vibrio vulnificus infection mainly manifests clinical subtypes such as primary sepsis, traumatic infection, and gastroenteritis, with rapid symptom progression and signs of multiple organ dysfunction syndrome (MODS). It is important to assess these pathogenetic mechanisms in order to select more appropriate measures to prevent and treat Vibrio vulnificus infections, including antibiotic usage and surgical intervention. In this work, we report a typical case of successful treatment of necrotizing fasciitis caused by Vibrio vulnificus, and review the epidemiology, pathogenetic mechanism, clinical characteristics, and treatment of Vibrio vulnificus infection.
