The invention discloses a GII.P12 / GII.3 recombinant
norovirus genome amplification primer and an amplification method. The amplification method comprises the following steps: by taking six pairs of amplification primers as forward and reverse primers of amplification primers respectively, and by taking
RNA of GII.P12 / GII.3 recombinant
norovirus as a template, performing RT-PCR amplification so as to obtain amplification products respectively, performing
nucleotide sequencing on the amplification products by using the six amplification primers and two sequencing primers II.12-Seq1R and II.3-Seq6F, and then carrying out jointing and comparison, thereby obtaining full-length sequences of a GII.P12 / GII.3 recombinant
norovirus genome. For the GII.P12 / GII.3 recombinant norovirus which occurs frequently in China, a sectional amplification strategy of '4+1+1'is designed according to three opening reading frames included in the
genome, corresponding amplification primers are designed according to conserved regions, the amplification primers are applied to practical detection samples, and GII.P12 / GII.3 recombinant norovirus genome sequences can be acquired. The GII.P12 / GII.3 recombinant norovirus
genome amplification primer and the amplification method can be widely applied to fields such as
medical treatment and
public health and inspection and
quarantine with norovirus detection requirements, and related scientific fields.
