  • Many hospitals use the Legionella urinary antigen test for initial detection when Legionella pneumonia is suspected. (wikipedia.org)
  • aerobic
  • Legionella organisms' dependence on L-cysteine and their unique fatty acids and isoprenoid ubiquinone distinguish them from other aerobic bacteria. (wikipedia.org)
  • This group has published guidelines about the actions to be taken to limit the number of colony forming units (i.e., the "aerobic count") of micro-organisms per mL at 30 °C (minimum 48 hours incubation): Almost all natural water sources contain Legionella and their presence should not be taken as an indication of a problem.

  • The US Centers for Disease Control (CDC) recommends routine monitoring for Legionella in all bone marrow and organ transplant hospitals nationwide. (bondwater.com)
  • The incubation period of the disease is two to 14 days after a person is exposed to the bacteria. (guardianlv.com)
  • The disease is not transmitted from person to person and most people exposed to the bacteria do not become ill. (guardianlv.com)
  • The disease is caused by a pneumonia-causing bacteria, Legionella pneumophila , often resident in contaminated water supplies, that infects people when aspirated. (wagwalking.com)
  • It was later determined that the water feature at the dog park had become contaminated with Leptospira bacteria from an infected dog's urine, and the disease had spread to other dogs at the park. (wagwalking.com)
