A new lineage of foot-and-mouth disease virus serotype O in India.

Abstract

The complete nucleotide sequence of a new lineage of foot and mouth disease virus (FMDV) serotype O was determined. The lineage designated as Ind2011 first appeared during 2011 in the Southern region of India. Excluding the poly C tract and poly A tail, the genome of Ind2011 ranged from 8,169 to 8,172 nucleotides. Variation in the genome length was due to insertions/deletions in LF-UTR. The lineage had a higher sequence identity with lineage PanAsia-1 at P1 and P2 regions, and with lineage PanAsia-2 at P3 and L regions. Phylogenetically, the isolates were placed closely to both PanAsia-1 and 2 lineages, and appear to be a novel variant of the PanAsian lineage.
