What is the average concentration of Legionella pneumophila serogroup 6 in hot-water samples from a specific ICU faucet?

• A. 19 CFU/mL
• B. 45 CFU/mL
• C. 70 CFU/mL
• D. 10 CFU/mL

Answer: (B)

The average concentration of Legionella pneumophila serogroup 6 in hot-water samples from a specific ICU faucet is identified as 45 CFU/mL. This concentration is important for understanding the risk of Legionella exposure in healthcare settings. High levels of this bacterium can present a significant health risk, particularly in vulnerable populations like patients in intensive care units. In many studies examining water samples in healthcare facilities, Legionella concentrations can provide insight into the effectiveness of water system management practices. An average concentration of 45 CFU/mL indicates that control measures might be necessary to reduce the risk of infection through aerosolized water sources such as faucets. While option B reflects a concentration that balances a measurable risk against typical expectations, the other concentrations do not align with the averages found in studies or may reflect situations that are not characteristic of typical ICU plumbing systems, thus shedding light on effective monitoring and control strategies for potable water in sensitive environments.
