ABSTRACT
<p><b>OBJECTIVE</b>To reveal the genetic characteristics of GII.12 Norovirus strains isolating from stool samples of adults with diarrhea in Beijing during 2008-2009.</p><p><b>METHODS</b>RdRp, ORF2, ORF3 and ORF1/ORF2 overlap region were respectively amplified by primers using RT-PCR. The products were purified, cloned, sequenced and then aligned, phylogenetic and recombinant analyzed by softwares of DNAStar, MEGA and SimPlot.</p><p><b>RESULTS</b>According to the phylogenetic analysis, 11 strains belonged to G II.g in the RdRp region,while GII.12 in the ORF2 and ORF3. SimPlot analysis further confirmed the 11 strains were recombinant strains ( G II.g [RdRp]/G II.12 [capsid]).</p><p><b>CONCLUSION</b>G II.12 Norovirus prevailing in Beijing and other regions of the world belonged to the same strain, and we identified the genetic characteristics of G II.12 Norovirus in Beijing.</p>
