摘要
军团菌是引起军团菌病的病原体。军团菌广泛存在于自然和人工水环境中,已在世界各地引起多起军团菌病爆发流行,其中空调冷却水也是一个重要的传染源,至今已有多起因冷却水嗜肺军团菌污染引起的军团菌病爆发。掌握空调冷却水军团菌污染状况,了解影响空调冷却水污染的因素及采取有效的预防控制和消毒措施可降低军团菌病爆发的危险。该文对空调冷却水中军团菌污染状况和污染影响因素以及预防控制措施作进行综述。
Legionnaires＇ disease is an atypical pneumonic illness caused by the legioneUa bacteria. These bacteria cause respiratory diseases when a susceptible host inhales aerosolised 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.
