[Etiological structure of respiratory infections in different variants of acute bronchitis].

The microbiological and virological examination of 87 acute bronchitis patients (36 patients with the prolonged course and 31 patients with the relapsing course of the disease) was carried out. All forms of bronchitis were characterized by a high degree of infection with respiratory viruses and pneumococci. Haemophilus influenzae (type b) infection was registered rather rarely and only in combination with pneumococcal one. The highest characteristics of viro-bacterial associations were found in patients with acute bronchitis and with prolonged form of acute bronchitis, viral associations--with the prolonged and relapsing forms of the course of acute bronchitis in the presence of the bronchoobstructive syndrome.
