RESUMO
Virological and bacteriological investigations were performed in 85 patients with acute pneumonias and virus isolation or serological evidence of virus infection were obtained in 37.6% of the cases. Influenza A2 and B viruses were incriminated in 14.1% of the patients; parainfluenza viruses in 7% and adenoviruses in 17.2% of the cases. Coxsackie virus was isolated from one patient's blood, and poliovirus 3 was recovered in 3 cases. In 5 cases associated virus infections were detected.

The viral etiology of acute respiratory diseases, determined in 107 children admitted to hospital during the 1966-1969 period, was confirmed in 36% of the cases by isolation of the viral agent and in 59% by serologic reactions. Parainfluenza viruses, especially of type 1 and 3, were encountered more often in the etiology of acute or obstructive laryngitis, and the syncytial respiratory virus in tracheobronchitis.

Bacteriologic and virologic investigations carried out in a group of 85 patients with acute pneumonia have allowed the determination of the etiologic agent in 52.9% of the cases. Of these, 40% showed combined viral and bacterial infections. Mixovirus infections were frequently associated with staphylococcic ones (7 out of 8 cases) and adenovirus infections with the pneumococcic ones (6 out of 7 cases). The most severe and longdrawn clinical pictures with frequent pleuropulmonary complications (in 22.24% of the cases) had a biphasic evolution in only 6 of the 18 pneumonias of mixed etiology. For their high frequency and their clinical peculiarities, mixed etiology pneumonias might be considered as distinct clinical entities.
