The halophilic organism among the listed options is which?

• A. Morganella morganii
• B. Plesiomonas shigelloides
• C. Vibrio parahaemolyticus
• D. Yersinia pestis

Answer: (C)

Halophiles are organisms that require or strongly tolerate higher salt concentrations for growth. Among common clinical bacteria, Vibrio parahaemolyticus is a marine, salt-tolerant organism; it thrives in saline environments and is often linked to seafood-related gastroenteritis. The other bacteria listed do not require high salt—Morganella morganii and Yersinia pestis grow best in lower-salt conditions, and Plesiomonas shigelloides is typically associated with freshwater and does not depend on salt for growth. Therefore, the halophilic organism is Vibrio parahaemolyticus.
