METHOD FOR DETECTING EMERGING PANDEMIC INFLUENZA
A method for detecting emerging pandemic influenza strains is provided. RT-PCR is used to detect HPAI followed by pyrosequencing to detect codons defining human or avian influenza signatures. This method screens for avian influenza viruses containing mutations suspected of making the virus more infective or virulent to humans.
1 . A method comprising sequencing RRT-PCR with pyrosequencing to identify high pathogenic avian strains and then detect mutations in the high pathogenic avian strains that render the virus more infective to humans.
2 . A method for detecting emerging pandemic influenza, the method comprising:
a) performing RRT-PCR to simultaneously detect multiple Influenza A virus subtypes and H5 strains; and
b) pyrosequencing targeted regions of gene segments of the H5 strain to determine if critical human virulence signatures are present.
3 . The method of claim 1 further including isolating virus RNA prior to performing RRT-PCR.
4 . The method of claim 1 further including amplifying gene segments prior to pyrosequencing.
5 . The method of claim 1 further including conducting mutation analyses of the critical human virulence signatures.
6 . A kit comprising materials required to perform the method of claim 2 .
7 . A method for detecting emerging pandemic influenza, the method comprising:
a) performing RRT-PCR to simultaneously detect multiple Influenza A virus subtypes and H5 strains;
b) amplifying gene segments of the H5 strain; and
c) pyrosequencing targeted regions of the gene segments of the H5 strain to determine if critical human virulence signatures are present.
8 . The method of claim 7 further including isolating virus RNA prior to performing RRT-PCR.
9 . The method of claim 7 further including conducting mutation analyses of the critical human virulence signatures.
10 . A kit comprising materials necessary for performing the method of claim 7 .
11 . A method for detecting emerging pandemic influenza, the method comprising:
a) isolating virus RNA;
b) performing RRT-PCR to simultaneously detect multiple Influenza A virus subtypes to detect H5N1 strain;
c) amplifying gene segments of the H5N1 strain; and
d) pyrosequencing targeted regions of the gene segments of the H5N1 strain to determine if critical human virulence signatures are present; and
e) conducting mutation analyses of the critical human virulence signatures.
12 . A kit comprising the materials required to perform the method of claim 11 .
