GENETIC DIVERSITY OF ADENOVIRUSES CIRCULATING AMONG THE MILITARY IN THE NORTH-WEST REGION.

The contribution of adenovirus (AV) infections to the overall structure of acute viral respiratory infections among young people of draft age can reach as high as 64.6%. Wide dissemination, the incidence of AV-associated pneumonias and lethal outcomes in the case of some complicated infections illustrate the urgency of studying the antigenic diversity of AVs circulating among the military. 991 nasopharyngeal swabs from patients hospitalized in military health facilities with symptoms of acute respiratory infections from 2014 to 2017 were detected by real-time PCR. Sanger sequencing was performed using forward and reverse primers matching the fiber gene. AVs were detected in 326 samples. In 80 of those, AVs were present in combination with other respiratory viruses, as follows: 26 with respiratory syncytial viruses (RSV), 49 with rhinoviruses, 2 with bocaviruses, 1 with RSV and rhinovirus, 1 with parainfluenza virus, and 1 with metapneumovirus. 31 samples were sequenced. Thirty AVs belonged to group E (serotype 4), and 1 AV belonged to group B (serotype 7).
