[Pathogenesis of rhinovirus infection].

Rhinoviruses (RV) are the etiological factors of not only acute respiratory diseases of the common cold type but also of acute and chronic diseases of otorhinolaryngological organs. Virological and bacteriological examinations of patients with chronic pneumonia in the stages of exacerbation and incomplete remission revealed a high degree of the infection activity. Virus-bacterial associations were frequently found. RV were isolated from the lower respiratory tract (bronchopulmonary secrete, biopsy materials). The association of RV with the involvement of the lower respiratory tract in patients with chronic pneumonia was demonstrated. Rhinoviremia was detected in one child dying with acute respiratory disease. The results of studies on some factors of specific and nonspecific immunity in patients with chronic pneumonia are presented.
