| Popis: | African swine fever (ASF), considered as the most dreadful swine disease due to its very high mortality, emerged in India in 2020. The complete genome analysis of ASF viruses isolated during the first outbreaks in India showed a few unique non-synonymous mutations in MGF 369-11L, MGF 505-4R, K205R and B263R genes. Frame shiftsin the protein coding sequences were observed in DP60R, ASFV-G_ACD 00190, MGF 110-10-L- MGF110-14L fusion, MGF 360-14L and I267L genes of Indian ASFVs as compared to ASFV/Georgia/2007. Complete genome based phylogenetic analysis of p72-genotype-II viruses showed the clustering of Indian isolates with ASFV/Wuhan/2019 in a separate clade. Phylogenetic analysis of concatenated sequences of 14 open reading frames (ORF) having single nucleotide polymorphisms (SNP) showed distinct grouping of Indian ASFVs with other Asian ASFVs.Thisis the first complete genome characterization of ASF viruses isolated from domestic pigs in India. The resultsindicate that number of Tandem Repeat Sequence in the intergenic region between I73R and I329L genes, and the 14 ORFs with SNP reported in this study could be the genetic determinants to differentiate the closely related p72-genotype II viruses circulating in Asia. |
