Cytomegalovirus (CMV) is a DNA-containing virus that is widespread worldwide and is of great importance in infectious pathology of children and adults.\r\nThe aim of this study is to evaluate the prevalence of CMV among children and immunocompromised patients in the Nizhny Novgorod region (central Russia) and to perform a phylogenetic analysis of the identified strains.\r\nMaterials and methods. DNA samples of CMV detected in frequently ill children and adult recipients of solid organs were studied. The genetic diversity of CMV was assessed for two variable genes: UL55(gB) and UL73(gN), using NGS technology on the Illumina platform. Phylogenetic trees were constructed in the MEGA X program, the reliability of the cluster topology on the trees was confirmed using the rapid bootstrap method based on the generation of 500 pseudo-replicas.\r\nResults. Circulation of 5 CMV genotypes by gene UL55(gB) and 5 genotypes by gene UL73(gN) was established in the territory of the Nizhny Novgorod region. While genotypes gB1 and gB2 dominated both in children and in adults, genotype gB5 was detected only in children. The spectrum of gN genotypes was more diverse: genotypes gN4a and gN3b prevailed in children, and gN1 and gN4b genotypes were predominant in adults. The obtained results allowed us to establish the similarity of the landscape of CMV genotypes circulating in Russia (Nizhny Novgorod region), Brazil, China and the USA.\r\nConclusion. The obtained data indicate the similarity of the landscape of CMV genotypes circulating in Russia (Nizhny Novgorod region), Brazil, China and the USA: in children, the predominant genotypes are gB1 (40.0%), gB2 (33.3%), gN4a (42.8%), and gN3b (28.6%), while in adults (recipients of solid organs) genotypes gB1 (37.5%), gB2 (37.5%), gN1 (26.3%), and gN4b (26.3%) are prevailed.<\/jats:p>","DOI":"10.36233\/0507-4088-277","type":"journal-article","created":{"date-parts":[[2025,1,15]],"date-time":"2025-01-15T19:52:34Z","timestamp":1736970754000},"page":"535-545","update-policy":"https:\/\/doi.org\/10.36233\/0372-9311-crossmark","source":"Crossref","is-referenced-by-count":0,"title":["Prevalence and phylogenetic analysis of cytomegalovirus (Orthoherpesviridae: &lt;i&gt;Cytomegalovirus: Cytomegalovirus humanbeta5&lt;\/i&gt;) genetic variants from children and immunocompromised patients in central Russia"],"prefix":"10.36233","volume":"69","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9838-1133","authenticated-orcid":false,"given":"Ol\u2019ga E.","family":"Van\u2019kova","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4582-5623","authenticated-orcid":false,"given":"Nina F.","family":"Brusnigina","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3710-6648","authenticated-orcid":false,"given":"Nadezhda A.","family":"Novikova","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"22004","published-online":{"date-parts":[[2024,12,15]]},"reference":[{"key":"ref1","doi-asserted-by":"crossref","unstructured":"Connoly S.A., Jardetzky T.S., Longnecker R.
