What is Legionella?

The Legionella organism is a Gram negative, rod shaped bacterium that can cause pneumonia (Legionnaires’ disease) or a flu-like illness (Pontiac fever). It was first identified and recognized as causing disease during the outbreak that occurred in conjunction with the American Legion Convention in Philadelphia in 1976. There are over 50 species of Legionella and 18 of those can cause disease. It is thought that the species Legionella pneumophila causes most of the infections.

Legionella is a fastidious organism, meaning it has specific growth requirements that need to be met in order for it to survive and grow. Some of these growth requirements are:

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.

Legionellosis is a water-borne disease caused by the bacteria Legionella pneumophila. The bacterium can cause severe pneumonia that could be fatal in 5% of patients. Legionnaires’ Disease was first identified after an outbreak at the American Legion convention in Philadelphia in 1976 grew out of the investigation of a series of pneumonia cases. Legionella bacteria is found naturally in freshwater, such as ponds and streams that evaporate. However, human activities can speed up its growth by providing conditions for the bacterium to flourish. This includes cooling towers, air conditioning systems and hot water tanks.
