ABSTRACT
Objective To identify the biological and molecular biological characteristics of SN7 virus isolated from Niviventer Confucianus in Sichuan province. Methods Monoclonal antibody, PRNT and PCR antigenicity analysis and genotyping of SN7 strain were performed. M and S segments of SN7 genome were also cloned and sequenced. The sequences were compared with those of other strains of Hantavirus. Results It was difficult to identify SN7 by using monocloncal antibody, PRNT and PCR. With sequence comparison, we found that strain SN7 had high homology(80.2%~87.1% of M segment and 76.6%~92.0% of S segment) with HTN type strains, and relatively low homology(70.0%~71.6% of M segment and 71.0%~72.2% of S segment) with SEO type strains. Strain SN7 was believed to belong to HTN type. Conclusions SN7 is a new subtype strain of HTN type viruses. It is possible that Hantavirus has immune escape in its natural hosts.
