Which bacterium is known for causing skin infections with blue-green discoloration?

• A. Listeria monocytogenes
• B. Pseudomonas aeruginosa
• C. Pasteurella multocida
• D. Escherichia coli

Answer: (B)

Pseudomonas aeruginosa is recognized for its ability to cause skin infections that often manifest with a characteristic blue-green discoloration. This discoloration is due to the production of pigments such as pyocyanin and pyoverdine, which are unique to this bacterium. Pseudomonas aeruginosa is opportunistic, meaning it frequently infects individuals with compromised immune systems or underlying health issues, making it a significant concern in clinical settings, particularly in burns and other wounds. Its prevalence in various environments, including soil and water, contributes to its ability to cause infections in different types of patients, leading to serious complications if not properly managed. Other bacteria listed may cause various infections, but they do not typically result in the distinctive blue-green pigmentation that is synonymous with Pseudomonas aeruginosa.
