Vibrio vulnificus is a well-established human pathogen that is known to cause which type of infection?

• A. Gastroenteritis
• B. Pneumonia
• C. Pyelonephritis
• D. Wound infections

Answer: (D)

Vibrio vulnificus is a marine bacterium classically linked to severe wound infections after skin exposure to saltwater or marine life. When a wound comes into contact with seawater, the organism can invade and cause rapid cellulitis or even necrotizing fasciitis, which is a hallmark presentation. While it can also cause septicemia after ingesting contaminated seafood (such as raw oysters), especially in people with liver disease, the most characteristic and well-established infection type is wound infection arising from seawater exposure. Pneumonia and pyelonephritis are not typically associated with this pathogen, making wound infections the best-known presentation.
