| 摘要 | Porcine reproductive and respiratory syndrome virus(PRRSV) has been mutating and evolving constantly since its emergence in the1980s, which has brought inestimable economic losses to the global swine industry. The virus has two genotypes, of which genotype 1 PRRSV(PRRSV 1) first broke out in Germany and mainly prevailed in Europe, which can be clustered into four subtypes based on the ORF5 sequence. Al-though few cases of PRRSV 1 have been reported in China, the prevention and control of PRRSV should not be ignored. The origin of PRRSV, ge-netic evolution and pathogenicity of PRRSV 1 were retrospectively analyzed, in order to provide valuable evidences for molecular epidemiology and immune prevention and control of PRRSV 1. |
