AbstractFoot and Mouth Disease (FMD) is the most economically important viral-induced livestock disease worldwide. From April to May of 2015, tongue epithelial tissue samples were collected from 36 cattle in six villages, which share the border with Iran. Samples were screened using RT-PCR to amplify a conserved region in the VP1 gene, and phylogenetic tree analysis was performed based on the VP1 nucleotide sequence results. Furthermore, the nucleotide sequence was converted to an amino acid sequence in order to detect similarities between the studied samples and those previously published in GenBank (NCBI). Epidemically, based on the amino acid residues, genetic similarity, and amino acid substitutions, the VP1 nucleotide sequences were determined to be close to a novel group, group VII, with 94% identity. The VP1 amino acid sequence analysis revealed a close relationship to the Asia/BAL/PAK/iso-2/2011 isolate (Accession no. JX435109), with 95.7% identity, which is not significantly different. Analysis of the studied samples revealed that the FMDV serotype Asia1 causing the outbreak in the Basne district belonged to group VII, which was introduced from the Balochistan province of Pakistan through illegal movement of animals from this region.
