Abstract
The present invention provides a primer set for detecting multiple influenza virus, including at least two primer pairs selected from the group consisting of: influenza B virus primer pair, H3 primer pair, H1 primer pair and H1N1 primer pair, wherein the primer pairs above respectively have a sequence at least 15 consecutive nucleotides set forth in SEQ ID NO: 1 and complementary sequence thereof, SEQ ID NO: 2 and complementary sequence thereof, SEQ ID NO: 3 and complementary sequence thereof, and SEQ ID NO: 4 and complementary sequence thereof, whereby the individual primer set is adapted to amplify specific PCR product of its corresponding haemagglutinin gene segment under an appropriate condition. The present invention also provides a primer for detecting multiple influenza virus.
