【摘要】 以犬用犬瘟热（ＣＤ）弱毒疫苗接种从产地新引入南京市玄武湖动物园的２只小熊猫（Ａ组），在接种后１１个月内每月采血１次，用微量中和试验检测其体内抗犬瘟热病毒（ＣＤＶ）抗体效价。结果显示，小熊猫接种后１个月时抗体效价已达１∶１０００左右，２个月时效价最高，达１∶２０００左右，而后缓慢下降，至７和１１个月时分别约为１∶１００和１∶２０。同时检测了以前接种过同一疫苗的３只该动物园自己繁育的小熊猫（Ｂ组）和福州市动物园内的６只小熊猫（Ｃ组）的ＣＤＶ中和抗体效价，其效价变化类似于Ａ组。这些小熊猫在接种前均确认健康，在试验期间同样的饲养条件下未发生ＣＤ，提示犬用ＣＤ疫苗可用于小熊猫的ＣＤ预防，其产生的有效免疫力至少可持续６个月。更多还原

【Abstract】 Two lesser pandas which newly introduced (group A) from their natural habitat into Xuanwu lake zoo in Nanjing were inoculated with attenuated canine distemper (CD) vaccine. Blood samples were collected once a month after inoculation during 11th month, antibody titer by microtitre neutralization test showed that group A was of about 1∶1000 in 1st month, increased to the highest about 1∶2000 in 2nd month, and then declined slowly througth the following months to 1∶100 in 7th month and 1∶20 in 11th month, respectively. Simultaneously, another 3 lesser pandas born in the zoo (group B) and 6 ones in Fuzhou zoo (group C), which were previously vaccinated with the same vaccine, were also detected, their changes of anti CDV antibody titers were similar with group A. These lesser pandas kept in good health before vaccination, No CD occurred in the raising condition during the experiment period. It suggesting that CD vaccine for dog could be applied for lesser panda and provide the efficient immunity of 6 month at least.更多还原
