| 1. | Hcv are a group of single - stranded rna viruses that belong to the flaviviridae family and hepavirus . all hcvs possess a positive - sense rna genome of approximately 9600 nucleotides
Hcv为有囊膜的单股正链rna病毒，属黄病毒科肝炎病毒属。 |
| 2. | Turnip mosaic virus ( tumv ) and cucumber mosaic virus ( cmv ) are two worldwide spread plant rna viruses , whose damages to host plants are utmost serious
芜菁花叶病毒( turnipmosaicvirus ， tumv )和黄瓜花叶病毒( cucumbermosaicvirus ， cmv )是两种世界范围内分布极为广泛、危害极为严重的植物病毒。 |
| 3. | After one - step reverse transcription of the rna virus genomes , the viruses " specific dna fragments were amplified by nested three loci pcr , which the amplification system was optimized by uniform design
选择合适的核酸抽提方法，一步法抽提hbv 、 hcv及hiv 1的病毒核酸并一步法逆转录病毒的rna ，获得病毒的dna 。 |
| 4. | Objective : borna disease virus ( bdv ) is a neurotropic nonsegmented negative - stranded rna virus that caused the illness calling borna disease ( bd ) . the illness is a nervous syndrome characterized by profound behavirol and consciousness abnormalities as well as encephalitis
目的：博尔纳病病毒( bornadiseasevirus ， bdv )是一种嗜神经性、非节段性、负股单链的rna病毒。 |
| 5. | And this virus is an rna virus and as professor tam was saying , the drugs that we re using , it seems to be consistent with our hypothesis and with the classification of this virus . because rna viruses theoretically can be treated with ribavirin , the drug we are using
因为有种影响引致我们的专家有部分估计是一种变种的病菌，我们现时看到的感染，当然一部分是病菌本身，譬如肺炎，通常这种病菌会引致肺炎，另一可能是身体对菌的反应会伤害自己身体。 |
| 6. | Successfully cloned and constructed infectious full - length cdna of attenuated lapinized csfv chinese - strain ( derived from spleen ) could make us get pure rna virus genome of csfv c - strain , and further study and utilize mutation , deletion , insertion and substitution of csfv gene on dna molecular level
中国猪瘟兔化弱毒(脾淋毒)全长感染性cdna的克隆和构建，可以使我们得到纯粹的csfvc -株rna病毒基因组，在dna水平上研究和利用csfv的基因突变、缺失、插入和替换。 |
