Which organism is commonly associated with wound infections?

• A. Legionella pneumophila
• B. Haemophilus influenzae
• C. Vibrio vulnificus
• D. Moraxella catarrhalis

Answer: (C)

Wound infections are often tied to bacteria that thrive in marine environments or at the interface with seafood, so exposure to warm seawater or raw shellfish points you toward organisms associated with those settings. Vibrio vulnificus lives in warm seawater and can invade through break in the skin, causing rapidly progressive cellulitis and even necrotizing infections, especially in people with liver disease or high iron levels. This makes it the organism most commonly linked to wound infections in scenarios involving marine exposure. Legionella pneumophila is mainly associated with pneumonia and systemic disease from contaminated water systems; Haemophilus influenzae and Moraxella catarrhalis are primarily linked to respiratory tract infections like bronchitis or sinusitis. So the wound-infection association best fits Vibrio vulnificus.
