Clinical Significance

The Legionella organism is a Gram negative bacterium that can cause pneumonia (Legionnaires' disease) or a flu-like illness. It is thought that the species Legionella pneumophila causes most of the infections.

Unlike some other bacteria, it can survive at lower temperatures (even below freezing), at lower dissolved oxygen levels and is somewhat resistant to chlorine disinfection. Certain plastics and organics can provide nutrients for growth. These attributes make our modern day plumbing systems a good habitat for the organism.
