Sampling and Detection of Legionella pneumophila Aerosols Generated from an Industrial Cooling Tower

摘要

Cooling tower water has frequently been cited as a source of infection in outbreaks of Legion- naires' disease. However, there have been few reports on the presence of legionellae in aero- sols from cooling towers. This paper describes our use of an impinger or a six-stage microbial impactor for detecting legionellae in air around a cooling tower contaminated with L. Pneum- aphila(1.2±0.3×105 CFU/100 ml).
