duck embryo meaning in Chinese
鸭胚
Examples
- In this research , the gpv hl isolate was propagated with 13 day ' s duck embryos . a pair of primers gflgr used to arnplify vp3 gene was designed using oligo4 . i software according to the whole nucleotide sequence of gpv b isolate published by zadori . the major structural protein vp3 gene was amplified from the dna of gpv hl isoiate by polymerase chain reaction ( pcr ) , and then cloned into pmdl8 - t vecter
根据zadori等发表的gpvb株全基因核苷酸序列，借助oligo4 . 1软件设计了1对用以扩增主要结构蛋白vp3基因的引物gf / gr ，通过pcr技术，从病毒基因组dna中扩增出病毒主要结构蛋白vp3完整基因片段，经酶切鉴定后直接与pmd18 - t质粒载体连接。 - Prevention and cure of the derzsy ' s disease depended on vaccine and antiserum , antibodies of eggs . the vaccines includes goose embryo and duck embryo vaccines which were used 1n breed goose and goslings , and those vaccines have great effect in breeding goose , but the entire virion live vaccines and attenuated vaccines exist many deficiencies . such as preclinical infection , dissemination of virus , recovery of viru5 , etc . those proplems can be sol / ed by producing genetic engineering " asclne
目前使用的疫苗分为种鹅用和雏鹅用的鹅胚和鸭胚化疫苗，这些疫苗在实际生产中发挥巨大作用，因其为全毒苗或弱毒苗，存在着潜伏感染，排毒散毒，毒力返祖的缺陷，基因工程疫苗的研制可解决上述问题。
