摘要
克隆并测定猪细小病毒 SY- 99株VP2基因 ,与 NADL- 2 ( 4 973)株、NADL- 2( 5 0 75 )株、Kresse株和 US- 1株 VP2基因核苷酸序列及其编码的氨基酸序列进行比较与分析 ,发现 PPV SY- 99株与 Kresse株 VP2基因核苷酸和氨基酸同一性最高 ,推测 SY-99株可能为一强毒株。
The VP2 gene of PPV SY 99 strain was cloned and sequenced. Nucleotide and amino acid identities of VP2 gene between SY 99 strain and NADL 2 strain, Kresse strain, and US 1 strain were conducted. The results showed that SY 99 strain is more closely related to Kresse strain than others and probably a virulent strain.
