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]
Legionella spp. enter the lungs either by aspiration of contaminated water or inhalation of aerosolized contaminated water or soil. In the lung, the bacteria are consumed by macrophages, a type of white blood cell, inside of which the Legionella bacteria multiply, causing the death of the macrophage. Once the macrophage dies, the bacteria are ...
In April 2000, an outbreak of Legionella pnemophila serogroup 1 occurred in Melbourne, Australia. The outbreak resulted in 125 confirmed cases of Legionnaire's disease, with 95 (76%) hospitalised. It is reported that 4 died from the outbreak.
"Legionella is a common bacteria found in the environment, and in water systems, especially hot water systems. Some species of Legionella bacteria can cause illness."
Legionella is often present in small quantities in the water cruise lines pick up in port for drinking, use in showers and amenities like whirlpool spas, but not high enough to make people sick ...
Legionella pneumophila, the primary causative agent for Legionnaire's disease, is an aerobic, pleomorphic, flagellated, non-spore-forming, Gram-negative bacterium. [ 1 ] [ 2 ] L. pneumophila is a intracellular parasite that preferentially infects soil amoebae and freshwater protozoa for replication.
Pontiac fever is an acute, nonfatal respiratory disease caused by various species of Gram-negative bacteria in the genus Legionella.It causes a mild upper respiratory infection that resembles acute influenza.
Legionella anisa is traditionally detected using the same culture methods as described for Legionella. However, some research suggests L. anisa may require a co-culture method that accounts for the close relationship with amoebae. When present in a sample but still contained within an amoeba host, the plating method may return false-negative ...
