Abstract:
Legionnaires’disease is an atypical pneumonic illness caused by the legionella bacteria.These bacteria cause respiratory diseases when a susceptible host inhales aerosolized water containing the bacteria or aspirates water containing the bacteria.Legionella are ubiquitous in natural and artificial water environments worldwide,and survive in a range of environmental conditions.Cooling towers have been implicated in many outbreaks of legionellosis.The causative organism has been readily isolated from many of cooling towers.Various physical and chemical disinfection methods have been developed to eliminate legionella from cooling waters,but gaining control of legionella in cooling water remains a challenge,more methods should be found to control legionella in cooling water.The related researches were reviewed in this paper.
