title: [Etiology of the infectious process in chronic pneumonia in children].
abstract: During the phase of exacerbation in chronic pneumonia in children Streptococcus pneumoniae and/or Haemophilus influenzae were isolated practically from all patients under examination. In the mild form of chronic pneumonia in children the high occurrence of H. influenzae (65.5-69%) was observed. During the whole acute phase of the disease, irrespective of the activity of the infectious process and the character of therapeutic measures, the degree of contamination of bronchial washings from the patients with these microorganisms was 5.95-6.6 lg/ml. In the bronchiectatic variant of chronic pneumonia the high activity and stability of the infectious processes induced by S. pneumoniae and H. influenzae were found to be linked with the considerable spread of these processes or with deeper morphological and functional changes in the bronchial stem and branches. During the phase of clinical remission in chronic pneumonia in 36.8-58.8% of children the release of S. pneumoniae and H. influenzae was observed. The geometric mean of their concentration varied within 3-5.3 lg/ml.
