What is the optimum temperature range for multiplication of Pseudomonas aeruginosa compared to Legionella?

• A. Higher than Legionella
• B. Lower than Legionella
• C. The same as Legionella
• D. Not relevant to Legionella

Answer: (B)

Pseudomonas aeruginosa has an optimum temperature range for multiplication that is generally lower than that of Legionella. Pseudomonas typically thrives optimally at temperatures between 25°C and 30°C, while Legionella pneumophila, the species associated with Legionnaires' disease, grows best at warmer temperatures, usually between 35°C and 45°C. This distinction is critical in the context of water systems and plumbing because it highlights the different environmental conditions in which these pathogens may proliferate, thereby influencing water management and monitoring strategies. By understanding that Pseudomonas aeruginosa prefers a lower temperature range, it becomes evident how temperature management in plumbing systems can help mitigate the risks associated with both pathogens but will require tailored approaches for prevention since they respond differently to temperature variations.
