Based on a recent webinar held by EMLab P&K featuring the Dr. Harriet Burge, Legionella is a gram negative bacterium that is a widely distributed natural inhabitants of water and is common in many environments. It is heat loving and will proliferate in temperatures between 20 degrees Celsius to 45 degrees Celsius. Growth is promoted by other micro organisms. Legionella is the causative agent of Legionellosis (Legionnaires' disease and Pontiac fever).
The first recognized outbreak of Legionnaires disease occurred in Philadelphia in 1976. As many as 221 people were treated and 34 deaths occurred. The source was identified as the Legionella bacterium and found in the cooling tower of the hotel's air conditioning system. Over 90% of legionelloses are caused by Legionella pneumophila.

This website routinely uses images from Wikipedia, which is a good thing, so no issue should be taken with using an presumably public domain image from their website. (Photo credit: Wikipedia)|
