水貂细小病毒性肠炎灭活疫苗保存期试验

Storage Period Test of Mink Parvoviral Enteritis Inactivated Vaccine

对2—8℃条件下保存90，120，150，180，210，240，300，360d的水貂细小病毒性肠炎灭活疫苗接种水貂进行免疫试验，结果表明：保存300d的疫苗接种水貂30d后血清中水貂肠炎细小病毒（MEV）HI抗体均在1：32以上，免疫水貂强毒攻击均获得100％保护，确定水貂细小病毒细胞灭活疫苗保存期为300d。该结果为水貂细小病毒细胞灭活疫苗运输和保存提供了理论依据。

Immune effect of the mink parvoviral enteritis inactivated vaccine which was stored for 90 d, 120 d,150 d,180 d,210 d,240 d and 300 d at 2- 8 22 were determinated, the results showed the HI titer of antibody against MEV was above 1 ： 32 after minks were inoculated for 30 d when the vaccine was stored for 300 d,and the challenging test showed the protection rate was 100% for minks inoculated, so the storage period of mink parvoviral enteritis inactivated vaccine was 300 d.
