IAQA Webinars: December 4, 2015: Legionella and other Bacteria

Although there are more than 10 million species of bacteria on earth, very few cause human illness. Of those species that do, only a small number have an airborne transmission. This webinar will discuss the impact of Legionella, filamentous bacteria and endotoxins on indoor air quality. You’ll learn why bacteria needs to be considered during a thorough air quality assessment.

Legionella bacteria

Legionnaires’ (LEE-juh-nares) disease is caused by a type of bacterium called Legionella (LEE-juh-nell-a). The bacterium is named after a 1976 outbreak, during which some people who went to a Philadelphia convention of the American Legion suffered from a new type of pneumonia (lung infection) that became known as Legionnaires’ disease. A milder infection, also caused by Legionella, is called Pontiac fever. The term “legionellosis” (LEE-juh-nuh-low-sis) may be used to refer to either Legionnaires’ disease or Pontiac fever.

General Information about gram-negative bacteria, E.coli

Gram-negative bacteria cause infections including pneumonia, bloodstream infections, wound or surgical site infections, and meningitis in healthcare settings. Gram-negative bacteria are resistant to multiple drugs and are increasingly resistant to most available antibiotics. These bacteria have built-in abilities to find new ways to be resistant and can pass along genetic materials that allow other bacteria to become drug-resistant as well. CDC’s aggressive recommendations, if implemented, can prevent the spread of gram-negatives.

Gram-negative infections include those caused by Klebsiella, Acinetobacter, Pseudomonas aeruginosa, and E. coli., as well as many other less common bacteria.
