The four experimental virus strains and the three collate virus strains were divided into two groups, and belonged two evolutionary branches. Although ADV-DL1, DL2 and DL3 were all belonged to the Da Lian separated strains, they had the ulterior genetic relationship. The nuclear sequences of the obtained experimental ADV virus strains, ADV virus collate virus strains and typify virus strains of other four Parvovirus generic were cladogram analyzed with the Clustal W method of software DNA Star.
结果表明,ADV-Utah与四个实验毒株的序列同源性较高,同源率为92.9-93.4%,ADV-G、ADV-SL3与实验毒株的同源性较低;四个实验毒株和三个参考毒株被分别划归为两个组,分属于两个进化分支;实验毒株中ADV-DL1与DL2和DL3虽然同为大连分离株,却表现出较远的亲缘关系。

One pair of primers that amplified the gB gene of pseudorabies viruswas designed and synthesized.PCR technique detecting the DNA of PRV was established after selecting the best reaction conditions.This technique was applied to specifically amplify the 281 bp DNA fragment of the PRV strains including Fa,Fb,Bartha,BJ,GD,V2F4,S,S3,SR,Buk,Shope,Norden,Mink Ⅲ,HB,F8,F9 and F12 in cultured samples.The negative results were achieved from Vero cells,swine vesicular disease virus,hog cholera virus,Japanese encephalitis virus,porcine reproductive and respiratory syndrome virus,porcine parvovirus,foot and mouth disease virus F29 strain,O3I3 strain,T509 strain and O Ⅱ MF249 strain.The results of sequencing showed that the PCR method was of specificity.The sensitivity of PCR reached 15.8 pg of PRV Fa strain DNA.The tissue samples obtained during 1994 and 2000 were detected,and the results showed that the sensitivity of PCR was more sensitive than virus isolation and the Sandwich ELISA.The PCR was applied to detect 191 tissue samples from 31 pig farms obtained from Guangdong,Fujian,Hainan Provinces during 1999 and 2000,50 samples(26.2%)were positive and 22 pig farms(71%)were positive.

After amplying a 2.2kb fragment form the PPV-SC1 RF-DNA,we clone the fragment into pMD 18-T,named pTNSl.The whole sequence which is 1989 bp long was determined by sequencing, including the complete ORF of PPV-SC1 NS1 which encoding 662 amino acids.Alignment of pairs of sequence indicates that there are 98% and 99% similary with other porcine parvovirus strains Kresse and NADL-2, respectively. Multiple sequence alignment discloses that there are a few difference between ppv-scl nsl gene and other ppv nsl gene: A-G at 39nt,T-C at 153nt,A-G at 175nt, A-C at 1117nt, A-C at 1535nt .Alternative codon in ppv-scl nsl have distinctly different frequentfy by codonbias analysis at EMBOSS(http://genopole.toulouse.inra.fr/bioinfo/emboss). Thereis not distinct hydrophobicity and transmenbrane helices in ppv-scl nsl protein. Struction domain anslysis of PPV-SC1 NS1 protein indicate that there are a ATP/GTP-binding site motif A at 398-405,16 Protein kinase C phosphorylation site,21 Casein kinase II phosphorylation site,and 3 cAMP/cGMP-dependent protein kinase phosphorylation site.At the same time ,there is a same motif between ppv-scl nsl and Poxvirus D5 protein-like which may share in the same fuction which is necessary during virion duplication.
将PPV-SC1 NS1序列与其他PPV NS1基因进行多序列比对,结果显示,PPV-SC1 NS1与其他的PPV NS1的同源性较高,仅存在个别的差异,分别是第39位A→G,第153位T→C,第175位A→G,第1117位A→C,第1535位A→C;同源搜索比较表明,PPV-SC1与PPV NS1同源性可达98%、99%,与其他的细小病毒NS1基因也存在很大的保守性;密码子偏向性分析结果表明PPV-SC1 NS1基因在同一氨基酸的不同密码子的选择上存在一定的偏向性;PPV-SC1 NS1蛋白总体上说具有亲水性不存在明显的疏水性区段,用swiss TMPRED软件预测PPV-SC1 NS1的跨膜区,返回的结果并没有得到有显著意义的跨膜区的存在;根据基于motif数据库的结构域预测,PPV-SC1 NS1的第393-415位氨基酸残基存在潜在的ATP/GTP结合位点,该蛋白还存在16个蛋白激酶C磷酸化位点,21个酪蛋白激酶2磷酸化位点,3个cAMP-/cGMP依赖蛋白激酶磷酸化位点,PPV-SC1 NS1蛋白与POX_D5(痘病毒D5蛋白)具有一致的保守结构域,推测NS1可能与POX_D5有类似的功能。
