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.展开更多

Van Broekhoven＇s survey of the natural law tradition and its relevance to the analysis of the controversial U.S. Supreme Court decisions. Then it addresses Mencius and the Chinese natural law tradition based on the researches of Hu Shih and John C. H.
