Legionella Pneumophila & Legionellosis
- Legionella is the genus of bacteria, which gives rise
to the risk of infection from diseases, collectively
known as legionellosis. These consist of both pneumonias
and non-pneumonic varieties. The species Legionella
pneumophila presents the most serious hazard, which
is mainly, but not solely, responsible for causing legionnaires'
disease. This is a pneumonia which has serious effects
and is fatal in 10-12% of cases.
Natural and Artificial Water Systems
Legionella is widespread in both natural water sources
and artificial water systems. It proliferates where
temperatures are favourable (20-45 Degrees C), nutrients
available and water is stagnant or recirculates. Infection
can then occur by the inhalation of aerosols or particles
generated from the source.
