| 摘 要： | 2006年以来,高致病性猪繁殖与呼吸综合征在我国造成了巨大的经济损失.位于NSP2基因上的30个氨基酸的缺失已成为区分我国2006年以来的PRRSV高致病性毒株和2005年以前的经典流行毒株的特异性标记.本试验在广东省分离到一个新型的PRRSV毒株BL2,其NSP2基因540位～563位(相对于VR2332 ORFIa...

| Abstract: | Highly pathogenic PRRS outbroke after 2006 in China had raised great economic loss.The 30 amino acid deletion on NSP2 gene had been identified as a unique hallmark for highly pathogenic PRRSV strains from previous classical strains.Unexpectedly,a 24 amino acid deletion was found on NSP2 gene of a novel PRRSV variant strain,named as BL2,was isolated in Guangdong province in China.The deletion in BL2 located at the same region on NSP2 gene(corresponding to aa 540-563 of VR2332 ORF1a),but was shorter than that... |
