However, their genomic diversity remains insufficiently characterized, with substantial geographic gaps in available sequence data, including for Russia, where only a few complete genomes have been deposited prior to this work. In this study, we analyzed more than 1200 PCR-positive respiratory specimens collected from hospitalized patients within routine surveillance projects and the Global Influenza Hospital Surveillance Network (GIHSN) across plenty of Russian regions during 2023\u20132024. Virus isolation followed by next-generation sequencing yielded 128 complete HAdV genomes representing species B, C, and D. The dataset included 27 B3, 9 B7, 44 B55, 12 C1, 16 C2, 4 C5, 7 C89, 5 C108, and one D109 genome, as well as three unassigned recombinant viruses with p89h5f5, p5h6f6 and p5h57f6 genomic structures (p, penton base; h, hexon; f, fiber). Phylogenetic analyses of whole genomes and capsid genes revealed extensive variability in immunogenic regions, particularly in species C, and identified clusters within B3 viruses. Notably, HAdV-D109 was identified in Russia, marking only the second reported detection of this genotype worldwide. Together, these findings substantially expand the currently available genomic landscape of HAdVs, highlighting the circulation of diverse and recombinant strains in Russia.<\/jats:p>","DOI":"10.3390\/v18010136","type":"journal-article","created":{"date-parts":[[2026,1,21]],"date-time":"2026-01-21T11:11:17Z","timestamp":1768993877000},"page":"136","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Nationwide Genomic Surveillance of Human Respiratory Adenoviruses in 2023\u20132024: Evidence of Extensive Diversity and Recombination in Russia"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1050-5817","authenticated-orcid":false,"given":"Nikita D.","family":"Yolshin","sequence":"first","affiliation":[{"name":"Smorodintsev Research Institute of Influenza, 197376 Saint Petersburg, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna A.","family":"Ivanova","sequence":"additional","affiliation":[{"name":"Smorodintsev Research Institute of Influenza, 197376 Saint Petersburg, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5961-1856","authenticated-orcid":false,"given":"Alexander A.","family":"Perederiy","sequence":"additional","affiliation":[{"name":"Smorodintsev Research Institute of Influenza, 197376 Saint Petersburg, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Irina V.","family":"Amosova","sequence":"additional","affiliation":[{"name":"Smorodintsev Research Institute of Influenza, 197376 Saint Petersburg, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tatyana A.","family":"Timoshicheva","sequence":"additional","affiliation":[{"name":"Smorodintsev Research Institute of Influenza, 197376 Saint Petersburg, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kirill A.","family":"Stolyarov","sequence":"additional","affiliation":[{"name":"Smorodintsev Research Institute of Influenza, 197376 Saint Petersburg, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daria M.","family":"Danilenko","sequence":"additional","affiliation":[{"name":"Smorodintsev Research Institute of Influenza, 197376 Saint Petersburg, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3643-7354","authenticated-orcid":false,"given":"Dmitry A.","family":"Lioznov","sequence":"additional","affiliation":[{"name":"Smorodintsev Research Institute of Influenza, 197376 Saint Petersburg, Russia"},{"name":"Department of Infectious Diseases and Epidemiology, Pavlov First Saint Petersburg State Medical University, 197022 Saint Petersburg, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1733-1255","authenticated-orcid":false,"given":"Andrey B.","family":"Komissarov","sequence":"additional","affiliation":[{"name":"Smorodintsev Research Institute of Influenza, 197376 Saint Petersburg, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,1,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Harrach, B.
