The causative agent of African swine fever (Asfarviridae: Asfivirus: African swine fever virus) (ASF) is a double-stranded DNA virus of 175\u2013215 nm. To date, 24 of its genotypes are known. Clustering of ASF genotype II isolates is carried out by examining a limited number of selected genome markers. Despite the relatively high rate of mutations in the genome of this infectious agent compared to other DNA viruses, the number of known genome molecular markers for genotype II isolates is still insufficient for detailed subclustering. The aims of this work were the comparative analysis of ASFV\/Zabaykali\/WB-5314\/2020 virus isolate and determination of additional molecular markers which can be used for clustering of viral genotype II sequences. Material and methods. ASF virus isolate ASFV\/Zabaykali\/WB-5314\/2020 was used to extract genomic DNA (gDNA). Sequencing libraries were constructed using the Nextera XT DNA library prepare kit (Illumina, USA) using the methodology of the next generation sequencing (NGS). Results. The genome length was 189,380 bp, and the number of open reading frames (ORFs) was 189. In comparison with the genome of reference isolate Georgia 2007\/1, 33 single nucleotide polymorphisms (SNPs) were identified, of which 13 were localized in the intergenic region, 10 resulted to the changes in the amino acid sequences of the encoded proteins, and 10 affected the ORF of ASF virus genes. Discussion. When analyzing intergenic regions, the ASFV\/Zabaykali\/WB-5314\/2020 isolate is grouped separately from a number of isolates from Poland and three isolates from People\u2019s Republic of China (PRC), since it does not harbor additional tandem repeat sequence (TRS). At the same time, the construction of a phylogenetic tree based on DP60R gene sequencing relates ASFV\/Zabaykali\/WB-5314\/2020 to isolates from PRC and Poland. Moreover, phylogenetic analysis of full-genome sequences confirmed previous studies on the grouping of viruses of genotype II, and as for the studied isolate, it was grouped with the variants from China. Conclusion. A new variable region was identified, the DP60R gene, clustering for which gave a result similar to the analysis of full-length genomes. Probably, further study of the distribution of ASF virus isolates by groups based on the analysis of this gene sequences will reveal its significance for studying the evolution of the virus and its spread.<\/jats:p>","DOI":"10.36233\/0507-4088-104","type":"journal-article","created":{"date-parts":[[2022,5,6]],"date-time":"2022-05-06T12:20:34Z","timestamp":1651839634000},"page":"153-164","source":"Crossref","is-referenced-by-count":2,"title":["Analysis of the whole-genome sequence of an ASF virus (Asfarviridae: Asfivirus: African swine fever virus) isolated from a wild boar (Sus scrofa) at the border between Russian Federation and Mongolia"],"prefix":"10.36233","volume":"67","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5982-8393","authenticated-orcid":false,"given":"A.","family":"Mazloum","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5438-8026","authenticated-orcid":false,"given":"A.
