The serotyping of 350 Streptococcus pneumoniae strains isolated from patients with acute and chronic diseases of the respiratory organs and from healthy children was carried out with the use of the agglutination test. 145 pleural fluid samples were tested for the presence of the pneumococcal antigen and its K-type. The prevailing pneumococcal serotypes were 6, 1, 19, 12 and 9 in acute pneumonia and 6, 19, 42, 3 and 12 in chronic pneumonia, including, respectively, 64.8% and 62% of all typed strains. Cases of pneumonia with complications in the form of pleuritis were mostly induced by serotypes 3, 1, 12 and 14, while in the destructive forms of pneumonia K-types 3, 14, 9 and 12 were isolated. Examinations of healthy pre-school children have shown 16.1% of them to be transitory pneumococcus carriers. Multiple biological examinations carried out during 1.5 years revealed that in this period 42.4% of the children were pneumococcus carriers.
