  “parent virus”译为未确定词的双语例句
     There was a great variation in inducing CPE between SA215 strain and SA215(A) strain: the time of SA215(A) inducing CPE on vero cell was prolonged, final plaque was smaller than parent virus SA215. SA215(A) wasneutralized by positive sera of PRV, SA215(A) was of serum properties of parent virus .

  parent virus
The long terminal repeats (LTRs) of equine infectious anemia virus donkey leukocyte-attenuated virus (EIAV-DLA) were substituted with those of the wild-type EIAV-L (wt EIAV-L, the parent virus of EIAV-DLA).
      
The growth characteristics of the EHV1ΔgG mutants were similar to the parent virus.
      
By serial passages of the reassortants in chick embryos non-aggregating variants were selected: the variants produced HA titers of the same order as A/USSR/90/77 parent virus.
      
All of the reasortants possessing NA genes of the H1N1 human parent virus and HA gene of an avian or mammalian parent virus had high values of infectivity/HA activity ratio.
      
Possible mechanisms involved in the alteration of pathogenicity between the SA 14 parent virus and the SA 14-14-2 vaccine virus are discussed.

The influenza A wild type virus, A/Fuzhou/8/58 ( H2N2 ) , replicated poorly in the nasal turbinates of hamsters, but replicated efficiently in their lungs.To determine which gene was responsible for this restriction of replication in the upper respiratory tract of the hamster, reassortant viruses were produced by mating the H2N2 virus with a H3N2 virus that replicates efficiently in both sites.A reassortant virus that contained all genes derived from the H3N2 virus except the hemagglutinin gene replicated poorly...

Rabies is one of the serious infective diseases in China. More than 5 million people per year are wounded by animals. The yield of hamster kidney rabies vaccine produced in China every year is not enough to meet the practical need. So we attempt to develop a Veto cell rabies vaccine with microcarrier system for large scale production. In this paper, the 'aG' virus strain, a Chinese rabies fixed virus used for preparing primary hamster kidney cell vaccine in China since 1980, was adapted in Vero cell. 2 adapted strains "RFD" and "HS_3" grew well in Vero cell and the virus titre of the supernatants was about 10~(-6·5)/ml(LD_(50)). The antigenicity and immunogenicity of 'RFD' and 'HS_3' did not show significant variation from their parent virus "aG" strain and have good cross-reaction with "CVS" fixed virus, Both of them could induce the laboratory animal such as mice, rabbits and dogs to develop neutralizing antibodies. It is suggested that these adapted strains could be used for promising candidates of virus seed for Vero cell rabies vaccine producion.

本文报道狂犬病毒Vero细胞适应株建株经过以及对适应株的抗原和免疫原性分析的情况,并推荐“RFD”和“Hs_3”适应株作为狂犬疫苗微载体培养系统的候选毒株。
