Legionella is a genus of gram-negative bacteria that can be seen using a silver stain or grown in a special media that contains cysteine, an amino acid. It is known to cause legionellosis[3] (all illnesses caused by Legionella) including a pneumonia-type illness called Legionnaires' disease and a mild flu-like illness called Pontiac fever.[3] These bacteria are common in many places, like soil and water. There are over 50 species and 70 types (serogroups) identified. Legionella does not spread from person-to-person.[4] Most individuals who are exposed to the bacteria do not get sick.[5] Most outbreaks result from poorly maintained cooling towers.

The cell wall of the Legionella bacteria has parts that determine its specific type. The structural arrangement and building blocks (sugars) in the cell wall help classify the bacteria.
