This study provides the frst comprehensive report on the molecular characteristics of African swine fever virus (ASFV) variants
in Serbia between 2019 and 2022. Since its frst observation in July 2019, the disease has been found in wild boar and domestic
swine. The study involved the analysis of 95 ASFV-positive samples collected from 12 infected administrative districts in Serbia.
Partial four genomic regions were genetically characterized, including B646L, E183L, B602L, and the intergenic region (IGR)
between the I73R-I329L genes. The results of the study suggest that multiple ASFV strains belonging to genotype II are circulating
in Serbia, as evidenced by the analysis of the IGR between I73R-I329L genes that showed the most diferences. Furthermore,
the phylogenetic analysis of the B602L gene showed three diferent clades within the CVR I group of ASFV strains. Regarding
the IGR, 98.4% were grouped into IGR II, with only one positive sample grouped into the IGR III group. These... fndings provide
essential insights into the molecular characteristics of ASFV variants in Serbia and contribute to the knowledge of circulating
strains of ASFV in Europe. However, further research is necessary to gain a better understanding of ASFV spread and evolution
