description The objective: To investigate etiological structure of adenoviral diseases in young people from organized groups and the clinical features of acute respiratory disease caused by different serotypes of adenovirus were identified.Materials and methods: A total 382 patients with adenovirusinfections were investigated. Virus isolation from nasopharyngeal swabs was carried out in cell cultures Vero, HeLa, Hep-2. Typing of adenoviruses was performed by virus neutralization test with polyclonal rabbit subtype specific sera. The average (M), standard deviation (SD) and frequency of occurrence (%) of clinical signs (respiratory and non-respiratory syndromes of pneumonia, protracted and recurrent course was calculated. Significance of the differences (p<0,05) of average frequency of cases compared to independent group of patients was evaluated by Student t-test and criterion φ2 (phi – square) Fischer, respectively.Results: As result of investigation 199 adenovirus strains (52,1 %) were isolated. 183 strains were serotyped: 64 (32,2 %) – 3 serotype, 42 (21,1 %) – 4 serotype, 38 (19,1 %) – 7 serotype, 15 (7,5 %) – 5 serotype, 11 (5,5 %) – 21 serotype, 8 (4,0 %) – 1 serotype, 3 (1,5 %) – 2 serotype, 2 (1,0 %) – 6 serotype. In assessing the features of the clinical course of adenoviral infection caused by the most actual serotypes (3, 4, 7) of adenovirus revealed that duration of diseases caused by serotype 7 was significantly longer and remained febrile fever (4,3±2,74 days, p<0,05), rhinitis (9,4±6,01 days, p<0,05), pharyngitis (7,9±2,87 days, p<0,05), laryngitis (7,3±2,87 days, p<0,05) and bronchitis (11,8±8,03 days, p<0,05), tonsillitis (63,0%, φ2=12,6, p<0,05), lymphadenopathy (63,0%, φ2=4,1, p<0,05), and pneumonia (34,2%, φ2=3,84, p<0,05) were registered significantly more frequently.Conclusion: The study showed that the adenoviruses of 3, 4 and 7 serotype have the greatest epidemiological significance. Clinical features of adenoviral diseases caused by 7 serotype were manifested in more frequent registration of non-respiratory syndromes and the development of pneumonia.
