[The clinical significance of finding Pseudomonas aeruginosa in the sputum]. / Klinicki znacaj nalaza Pseudomonas aeruginosa u sputumu.

Pseudomonas aeruginosa is an ubiquitous microorganism, which is characterised with low virulence and moderately sensitive to antibiotics. Significance of identification of the bacteria in the sputum varies. In severe cases, exhausted by more simultaneous diseases, it can be manifested as a pathogenic agent. At the Institute of Pulmonary Diseases and Tuberculosis, UCC in Belgrade Pseudomonas was isolated in the sputum samples of 48 patients. The organism was apathogenic in 28 (59%) cases, in 17 (35%) cases it caused chronic suppuration, and in 3 (6%) pneumonia. No specific antipseudomonas therapy is needed in patients in good general condition, contrary to cases of manifested infection where two antibiotics, physical therapy and other measures are indicated. Basic disease determines prognosis of the infection course. Medical approach to this problem should be characterised by prevention of the infection occurrence.
