[Etiological diagnoses in 53 cases of pneumonia].
Secretion was taken from lower respiratory tract for bacterial culture using Japanese made single-sheath catheter brush (SSC) via fiberoptic bronchoscopy in 53 cases with community acquired pneumonia and 16 control cases without pulmonary infection. The results showed that bacteria were isolated in 42 out of the 53 patients, the organisms being pathogenic in 39 out of the 53 (73.5%). Among the bacteria isolated from the 42 cases, gram-negative bacilli accounted for the highest rate of 36% and pneumococcus the next of 31%. There were only 3 cases yielding contamination. It is shown that SSC technique has less chance of contamination and is convenient and practical.
