[Molecular characterization of hantavirus Zhejiang isolate ZT10 strain from M. fartis].

Objective: To learn about the complete genomic sequence of the Seoul virus strain ZT10 isolated from M. fartis.

Methods: The total RNA was extracted from the infected Vero E6 cells and amplified by RT-PCR. The purified PCR products were cloned into T-vector and sequenced.

Results: The results demonstrated that the complete genome of ZT10 was comprised of L(6530), M(3651) and S(1753) segments which encoded 2151-1133 and 429 amino acids respectively.

Conclusion: Analysis of sequence revealed that the ZT10 belonged to Seoul virus. The nucleotide sequence identity of the M gene with Seoul virus was 84.0%-96.3%. The identity with Hantan vrisu (Prospect Hill virus, Tula virus) isolated from M. fartis was 57.5%-60.9%. The sequence identity of the S gene with Seoul virus was 87.9%-96.0% at nucleotide level and 96.9%-97.9% at amino acid level.
