An example of a halophilic microorganism is which species?

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

Answer: (D)

Halophiles are organisms that require salt or tolerate high salt concentrations to grow. Vibrio parahaemolyticus is a marine bacterium that thrives in saline conditions, so it is a classic example of a halophilic microorganism. Morganella morganii, Yersinia pestis, and Plesiomonas shigelloides do not require salt for growth and are not classified as halophiles; they grow well on standard media and are associated with non-saline environments, freshwater, or human/animal hosts rather than salty habitats.
