Legionella pneumophila
Legionella is a type of ‘microbe’ that inhabits natural environments as soil, rivers and water bodies. Legionella proliferates in poor sanitary conditions of water circulation systems such as hot water systems, humidifiers, hot tubs (sauna), heat rejection equipment of air conditioning and industrial cooling water systems.
The infectious disorder caused by this Legionella bacteria is called Legionnaires’ disease, associated with high fever and respiratory complications, nausea, and impaired consciousness and may rapidly progress to a severe level and cause death. Care must be given to people with weak resistance, such as infants and the elderly, and those immunocompromised patients.
