Abstract: In order to develop a simple and quick method to detect H1 subtype avian influenza virus (AIV),two pairs of primers were designed according to the sequences of HA gene of H1 subtype AIV, and a nested polymerase chain reaction (nPCR) method was developed for detection of H1 subtype AIV. The specificity and sensitivity test showed that this nPCR was only specific to the H1 subtype AIV and could detect 13.2 fg/μL of AIV RNA. The results demonstrated that the optimized nPCR assay was rapid, specific and sensitive for detection of H1 subtype AIV.

Key words: H1 subtype avian influenza virus; nested PCR; detection
