[Viral and bacterial associations and their role in the development of bronchopulmonary diseases in children].

Clinical and laboratory criteria for estimating the role of viruses and bacteria that determine bronchopulmonary diseases have been derived. The clinical importance of the detectable microflora, part of which permanently invade the nasopharynx (pneumococcus, adenoviruses) is under critical review. Pneumonias that may develop within the first days of acute respiratory viral infection are characterized by monoviral influenzal or RS-infection; later pneumonias are marked by viral infection with the predominance of adenoviruses.
