Abstract: Equine influenza virus, A/Equi-2/Ludhiana/87 H3N8 isolated from influenza epizootic in India in 1987 was characterized for its uniqueness by sequencing of its neuraminidase gene as the vaccine prepared with this isolate is still in use and has not been updated for more than a decade. Comparison of the nucleotide and amino acid sequences of this gene with other H3 N8 isolates revealed that Indian isolate had maximum differences with avian like equine influenza isolate (Jilinl89) and had resemblance with equine influenza H3N8 isolates namely Alaska/91, Tennessee/86, NewmarketJ79 and KentJ87 which further indicated that it belongs to the lineage of currently circulating H3N8 equine viruses in equine population.
