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 ...
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]
You can contract Legionnaire's disease by inhaling the bacteria (legionella), but NOT from person to person contact. Because it is a disease that affects the lungs, older adults, smokers and ...
[12] [13] An outbreak caused by Legionella micdadei in early 1988 in the UK became known as Lochgoilhead fever. [14] Since that time, other species of Legionella that cause Pontiac fever have been identified, most notably in New Zealand, in 2007 where Legionella longbeachae was discovered. The New Zealand outbreak also marked the first time ...
Legionnaires' disease is caused by inhaling water droplets contaminated with the Legionella bacteria. The bacteria can grow in water droplets from showers, hot tubs, faucets, cooling towers ...
Legionella is a common bacteria found in the environment and in water systems. It can cause a severe type of pneumonia - Legionnaires' disease - which impacts lungs, or a mild flu-like illness ...
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.
According to the CDC, Legionella bacteria can cause a serious type of pneumonia, known as Legionnaires disease or Pontiac fever. Legionella bacteria is spread through the air when an individual ...
