Hur sprids sjukdomen Legionella?
Smitta sker genom inandning av vatten i aerosolform eller inandning av jord. Att få i sig bakterien via dryck orsakar inte sjukdom. Smitta mellan personer förekommer inte. Man kan inte bli kronisk bärare av Legionella.
Hur lång tid tar det innan Legionella att bildas?
Legionellabakterien trivs i temperaturer mellan 20°C och 45°C Allra mest förökar den sig i temperaturer mellan 35 °C och 40 °C. Däremot dör den om temperaturen blir för hög. Om temperaturen i varmvatteninstallationen är 50 °C tar det mellan 5 och 10 timmar att ta död på 90 procent av bakterierna.
What is Legionnaires’ disease caused by Legionella pneumophila?
Legionnaires’ Disease Caused by Legionella pneumophila Serogroups 5 and 10, China. To the Editor: Legionnaires’ disease is a systemic infection caused by gram-negative bacteria belonging to the genus Legionella. The primary clinical manifestation is pneumonia. Legionella spp. are typically found in natural and artificially hydrated environments.
Is Legionella pneumophila Gram positive or negative?
Legionella pneumophila. Legionella pneumophila is a thin, aerobic, pleomorphic, flagellated, nonspore-forming, Gram-negative bacterium of the genus Legionella. L. pneumophila is the primary human pathogenic bacterium in this group and is the causative agent of Legionnaires’ disease, also known as legionellosis.
What is the treatment for Legionella pneumophila?
Treatment. Legionella pneumophila is an intracellular organism. Effective treatment therefore requires an antibiotic that reaches sufficient intracellular concentration (Roig and Rello, 2003). Macroazalides and fluoroquinolones are two classes of antibiotic that combine high potency with cellular penetration.
What happens if you breathe in Legionella?
After Legionella grows and multiplies in a building water system, water containing Legionella can spread in droplets small enough for people to breathe in. People can get Legionnaires’ disease or Pontiac fever when they breathe in small droplets of water in the air that contain the bacteria.
