Primer composition assisting identification of European avian like H1N1 subtype swine influenza virus and applications thereof

The invention discloses a primer composition assisting identification of a European avian-like H1N1 subtype swine influenza virus and applications thereof. The primer composition comprises a primer pair B. The primer pair B comprises a single-stranded DNA molecule shown as a sequence 3 in a sequence table and a single-stranded DNA molecule shown as a sequence 4 in the sequence table. The primer composition also comprises a primer pair A. The primer pair A comprises a single-stranded DNA molecule shown as a sequence 1 in the sequence table and a single-stranded DNA molecule shown as a sequence 2 in the sequence table. The primer composition and applications thereof have positive meanings for real-time diagnosis, suppression of epidemics, and large-scale epidemic disease monitoring of the European avian-like H1N1 subtype swine influenza virus.
