The genes noted above affect the production of interferon-λ3, which is involved in restriction of the viral replication.</p><p><strong>Materials and methods: </strong>Samples from 456 patients with mild (<i>n </i>= 150), moderate (<i>n </i>= 173), and severe (<i>n </i>= 133) influenza were studied. The viral RNA was detected by reverse transcription and polymerase chain reaction (RT-PCR). Polymorphisms in <i>IFNL3</i> (rs8099917 T/G) and <i>IFNL4</i> (rs12979860 C/T) genes was detected by PCR. Statistical analysis was performed using SNPStats software.</p><p><strong>Results: </strong>Patients with the C/T or T/T genotype of <i>IFNL4</i> gene (rs12979860 C/T) were more likely to have pneumonia than those with the C/C genotype (OR 2.47 (1.31-4.63); <i>p </i>= 0.0044; <i>q</i> = 0.0059). The presence of one T allele increased the risk of developing pneumonia (OR 2.02 (1.05-4.02); <i>p </i>= 0.006; <i>q</i> = 0.008). In the presence of the T/T genotype, the risk increased more than twofold: OR 2.14 (1.31-3.48). Analysis of the SNP of <i>IFNL3</i> gene (rs8099917 T/G) revealed a weak association of the G allele with pneumonia (OR 1.86 (1.04-3.31); <i>p</i> = 0.03; <i>q </i>= 0.045).</p><p><strong>Conclusion: </strong>Genetic markers of increased risk of community-acquired pneumonia in influenza include the presence of the T allele in <i>IFNL4</i> gene (rs12979860 C/T) and, to a lesser extent, the G allele in <i>IFNL3</i> gene (rs8099917 T/G).

Respiratory diseases are also an important cause of morbidity and mortality in wild populations, and most of these infections can affect humans. Many anthropoid species, including apes, are susceptible to ARVI. Outbreaks of spontaneous respiratory infections have been described in many zoos and primatological centers around the world. Moreover, the study of spontaneous and experimental infection in laboratory primates provides an invaluable source of information on the biology and pathogenesis of ARVI and remains an indispensable tool for testing vaccines and drugs. The aim of this literature review was to summarize and analyze published data on the circulation of ARVI causative agents (parainfluenza viruses, adenoviruses, respiratory syncytial virus, influenza viruses, rhinoviruses, coronaviruses, metapneumoviruses, bocaviruses) among wild and captive primates, as well as the results of experimental modeling these infections in monkeys.</p>","PeriodicalId":23669,"journal":{"name":"Voprosy virusologii","volume":"70 1","pages":"7-24"},"PeriodicalIF":0.0,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144042590","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
