[Etiology of pneumonias in young children according to data from comprehensive immunomicrobiological, virological and parasitological studies].

Investigations carried out demonstrated acute pneumonia in young children to be characterized by the presence in the sputum from the deep respiratory tract of polymicrobial flora, in some of viral-microbial-fungus flora, and also of pneumocysts. Immunobiological and virological study demonstrated the etiological role of 7 virus species and 2 bacteria species in 70.8% of cases; pneumonia of viral etiology constituted 24.

[Antibiotic sensitivity of the bacterial microflora from the sputum of children with acute pneumonia].

Bacteriological analysis of sputum of 598 children with acute pneumonia was performed. Sensivity of 1348 cultures belonging to 8 bacterial species with respect to benzylpenicillin, streptomycin, chloramphenicol, tetracycline, oxytetracycline, chlortetracycline, erythromycin, oleandomycin, neomycin and monomycin was determined. It was shown that the sputum microflora was often resistant to the antibiotics widely used in the medical practice for prolonged periods of time, such as benzylpenicillin, streptomycin, chloramphenicol, tetracyclines.
