摘　　要：目的:比较3种毒株(aG、CTN、CaG)制备疫苗的免疫原性及抗狂犬病毒攻击的能力。方法:应用ELISA法测定3种毒株制备的疫苗免疫家兔、豚鼠、地鼠所获的免疫血清效价;并通过用上述的地鼠免疫血清中和3种病毒后进行小鼠的中和试验。结果:在家兔、豚鼠两组内,细胞适应株毒种制备的疫苗(CaG和CTN株)血清免疫效价明显高于豚鼠脑毒种(aG株)。细胞适应株毒种制备的疫苗免疫地鼠所获得的免疫血清中和3株病毒的能力高于豚鼠脑毒种。结论:使用细胞适应株毒种生产狂犬病疫苗较豚鼠脑毒种具有更好的免疫原性。To compare immunogenicity of vaccine produced by three rabies virus stains( aG-,CTN.,CaG) respectively and determine their the ability against lethel challenge of rabies virus.Methods: By ELISA to determine sera potency of rabbits as well as hamsters and guinea-pigs which have been vaccinated different rabies respectively .To neutralize three different rabies strain with sera of hamster vaccinated and carry on neutralization experiments in mice.Results:In rabbits and guinea-pigs groups,rabies vaccine protency(by ELISA determination) vaccinated cell-adapted virus strain (CaG and CTN) is higher than one of vaccinated guinea-pig' strain virus strain's (aG), sera ability of hamster vaccinated cell-adapted strain against three rabies virus lethel challenge is higher than one of guinea-pig strain virus strain' g, too. Conclusion: Immunogenicity of rabies vaccine produced by cell-adapted strain is better than one of guinea-pig'sbrain virus strain's.
