Community Acquired Pneumonia in Telemark and Ostfold
Community Acquired Pneumonia in Telemark and Ostfold
The aim of the study is to investigate the bacterial causes in community acquired pneumonia
 in adults admitted to hospital in two counties in Norway and to look at possible factors that
 makes the patients susceptible to pneumonia.
In Norway there is little knowledge of which bacterias that causes pneumonia in patients
 admitted to hospital. There are also few registered cases of Legionnaires disease every year,
 compared to our neighbour countries.

 Therefore 500 patients with community acquired pneumonia admitted to Telemark hospital and
 Ostfold hospital in Norway will be tested by urin antigen test for the detection of
 Legionella pneumophila serogroup 1 and Streptococcus pneumoniae. We will also perform routine
 bacterial culture of sputum and culture on medium for isolation of Legionella species. A
 throat swab from the patients will be tested for Mycoplasma pneumoniae, Chlamydophila
 pneumoniae and Bordetella pertussis using PCR-techniques. Legionella-serology will also be
 performed. In addition all the included patients are invited to fill in a questionnaire in
 order to look for risk factors for developing community acquired pneumonia.
