[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 24.1 +/- 3.0%, of bacterial -- 24.6 +/- 3.0%, and of viral-bacterial -- 22.1 +/- 2.0%. In order to unify the approaches and methods of study of pneumonia etiology in young children complex immunomicrobiological, virological, and parasitological method of study is suggested.
