摘要: |
对不同保存年代的鸡新城疫疫苗种毒HB1株(Ⅱ系)和F株(Ⅲ系)各3批进行了病毒含量测定和免疫原性试验。3批不同保存年代的鸡新城疫病毒HB1株和F株病毒含量均≥108.4EID50/0.1mL,最小免疫量均≤2500EID50。结果表明鸡新城疫病毒HB1株和F株毒种在-70℃分别保存16年和19年病毒含量和免疫原性仍符合《中华人民共和国兽用生物制品规程》(二〇〇〇年版)规定。 |

Abstract: |
The virus titers and immunogenicity of three batches master seeds of Newcastle disease live vaccine strain virus (HB1,class Ⅱ & F,class III; stored in -70℃ for different times) has been tested. The virus titers were all above 108.4EID50/0.1mL and the immune minimum doses were all below 2500EID50. It show that the virus content and immunogenicity of the master seeds of Newcastle Disease virus (HB1,class Ⅱ & F,class III) stored in -70℃ for 16 years or 19 years still conformed the regulations of The People's Republic of China Veterinary Biological Products ,2000 edition. |
