[Bacterial flora of respiratory tract infections].

In this paper the bacterial flora of respiratory tract diseases of children and adults was described. Significant differences in the frequency of isolation of various species of bacteria in connection with the age and the clinical form of disease were observed. Haemophilus influenzae was isolated from the accessory sinuses of the nose of children with significantly higher frequency than from adults. This microorganism occurred as the only etiological agent in more than 50% of cases.
