Molecular characterization of foot-and-mouth disease virus O/SKR/2000

Molecular cloning and sequencing of the genome of foot-and-mouth disease virus (FMDV) O/SKR/2000, one of PanAsia strain, were performed from FMDV infected cattle. From the poly (C) tract of the 5′ nontranslated region (NTR) to the 3′ NTR including 14 base pairs (bp) of poly (A) tail, 7813 bp sequences comprising approximately 95% of the whole genome were obtained by reverse transcription polymerase reaction (RT-PCR). The deduced amino acid sequences of the structural and nonstructural proteins (NSP) of the O/SKR/2000 virus were analyzed for the sequence similarity among type O strains. Comparison between FMDV O/SKR/2000 and other strains indicates that overall the number of amino acids appears to be conserved without any deletion in either NSP or capsid proteins, thus, suggesting that O/SKR/2000 evolved with minor difference from preexisting strains.
