Legionella pneumophila

What is Legionella pneumophila?

Legionella pneumophila is a gram-negative, aerobic bacterium that was isolated and named after the first recognized outbreak of Legionnaires’ disease in 1976. It is one of more than 61 strains of Legionella bacteria, which are widely found in natural and artificial aquatic environments, soils, and composts.6 Legionellae can grow intracellularly in protozoa, and some strains have infected humans. L. pneumophila causes 97% of Legionnaires’ disease cases and 100% of deaths from outbreaks of Legionnaires’ disease.
