LEGIONELLA (TREATMENT AGAINST BACTERIA):
WHAT IS LEGIONNAIRE’S DISEASE?
Legionnaires’ disease (also known as Legionellosis or Legion fever) is a form of pneumonia caused by any species of Gram-negative aerobic bacteria belonging to the genus Legionella. Over 90% of cases of Legionnaires’ disease are caused by Legionella.
Legionella pneumophila is a thin, aerobic, flagellated, non-spore forming, gram-negative bacterium of the genus Legionella. Legionella pneumophila can be found in aquatic systems where it is symbiotically present with aquatic-borne amoebae. It also thrives in temperatures between 25 and 45OC with an optimum temperature of 35OC.
MODE OF TRANSMISSION
- Legionnaires’ disease is transmitted by inhalation of vaporized water.
- It is not airborne and not transmitted from person-to-person.
- Sources where temperature allow the bacteria to thrive include the following:
- HOT TUBS
- HOT WATER TANKS
- COOLING TOWERS
- EVAPORATIVE CONDENSERS OF LARGE AIR-CONDITIONING SYSTEMS.
A person usually develops Legionnaires’ disease 2 to 10 days after exposure to Legionella bacteria. A person affected with the disease shows the following symptoms:
- Fever that may be 40OC
- Cough that is usually accompanied by phlegm or blood.
- Shortness of breath
- Nausea, vomiting, and diarrhea
- Confusion or other mental changes.
