    Abstract:
    Foot-and-mouth disease (FMD), the most economically important disease of cloven-hoofed animals, is endemic in India. Sequence analysis revealed that phylogenetic grouping of type Asia1 field isolates on the basis of the large fragment of the 5'untranslated region (5'LF-UTR) was quite similar to that based on the sequences of the capsid-coding (VP1) region of the same viruses. The existence of two distinct lineages of type Asia1 suggested by the study on the VP1 region was further supported by the detection of a difference in length and predicted secondary structure of the 5'LF-UTR between the two lineages. Sequence variability between the isolates of the two lineages was also observed within the different domains of the internal ribosome entry site (IRES) around conserved motifs like the GNRA,- RAAA,- and the polypyrimidine tract. Certain group and lineage-specific signature nucleotides pertaining to FMDV type Asia1 in the 5'LF-UTR have been identified. The present study shows that the 5'LF-UTR of FMDV serotype Asia1 field isolates are variable in relation to the length and probable secondary structure of the IRES.
