Genotype of hantavirus in Zhejiang province / 中华实验和临床病毒学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To identify the genotype and clades of hantavirus (HV) in Zhejiang province.</p><p><b>METHODS</b>The partial S and M segment of the HV in Zhejiang province were amplified with RT-PCR using genotype-specific primers, and then were sequenced and compared with other known hantaviruses.</p><p><b>RESULTS</b>The genotype of 11 strains were HTNV and other 7 strains were SEOV by homology and phylogenesis analysis, yet the clade distribution was significantly different among foci of Zhejiang with 5 clades of HTNV and 3 clades of SEOV. There also existed special clade of HTNV named ZNB-1, ZNB-2, A3 and of SEOV named Gou3, ZJ5. The homology of M segments of ZNB-1 and ZNB-2 with other HTNV clades were 69.7%-74.0% except Nc167, A3 with other HTNV clades were 73.6%-76.3% except B78.</p><p><b>CONCLUSION</b>Zhejiang province is co-circulating with HTN and SEO. Say the least of the clades are 5 of HTNV and 3 of SEOV and there also existed special clade of HTNV and SEOV.</p>
