[Comparative characteristics of the Haemophilus influenzae strains isolated from healthy children and from patients with acute and chronic bronchopulmonary diseases].

The comparative biochemical and serological characterization of 424 H. influenzae strains isolated from healthy children and patients with acute and chronic bronchopulmonary diseases is presented. As the result of biotyping H.

[Etiology of acute and chronic bronchopulmonary diseases in children. II. A study of the specific immune response by counterimmunoelectrophoresis and the complement fixation and passive hemagglutination reactions].

Specific immune response to Streptococcus pneumoniae and Haemophilus influenzae has been studied in 158 children with acute pneumonia and pleuritis and 128 children with chronic pneumonia by countercurrent immunoelectrophoresis (CIE) and in the complement fixation (CFT) and passive hemagglutination (PHA) tests. The use of CIE leads to the detection of antibodies to H. influenzae in 23.

[Etiology of acute and chronic bronchopulmonary diseases in children. I. The results of a bacteriological and immunological study].

The bacteriological study of tracheal aspirate, sputum and bronchial washings obtained from 130 children with acute pneumonia and pleuritis and from 186 children with chronic pneumonia was carried out. In the samples of pleural exudate, urine and blood serum from the patients with acute pneumonia and pleuritis the presence of Streptococcus pneumoniae and Haemophilus influenzae antigens was determined by the method of countercurrent immunoelectrophoresis (CIE).
