摘要
为了制定合理、有效的肉鹅坦布苏病毒病免疫程序,选取鸭坦布苏病毒病灭活疫苗(HB株)和弱毒疫苗(FX2010-180P株)对7日龄和14日龄浙东白鹅进行不同疫苗组合(7日龄灭活苗+21日龄灭活苗组(A组)、7日龄弱毒疫苗组(B组)、7日龄弱毒疫苗+21日龄灭活苗组(C组)、14日龄灭活苗+28日龄灭活苗组(D组)、14日龄弱毒疫苗组(E组)、14日龄弱毒疫苗+28日龄灭活苗组(F组)、未免疫组(G组))的试验,用双抗体夹心ELISA法检测免疫后不同时间的抗体含量.结果表明:弱毒疫苗免疫组产生抗体较其他组快,但抗体含量持续时间较短;灭活疫苗+灭活疫苗(A组和D组)抗体含量从免疫完成后第24～36天抗体含量均高于弱毒疫苗(B组和E组)和弱毒疫苗+灭活疫苗(C组和F组),抗体持续时间更长.建议肉鹅可在14日龄用坦布苏病毒病灭活疫苗进行首免,14 d后再接种一次,可获得较高的抗体含量.
Abstract
In order to formulate a scientific and efficient vaccination procedure of Tembusu virus disease in meat geese,inactivated vaccine(HB strain)and attenuated vaccine(FX2010-180P strain)of duck Tembusu virus disease were se-lected to carry out different vaccine combinations(7-day-old inactivated vaccine+21-day-old inactivated vaccine group(group A),7-day-old attenuated vaccine group(group B),7-day-old attenuated vaccine+21-day-old inacti-vated vaccine group(group C),14-day-old inactivated vaccine+28-day-old inactivated vaccine group(group D),14-day-old attenuated vaccine group(group E),14-day-old attenuated vaccine+28-day-old inactivated vaccine group(group F),non-immunized group(group G))test on 7-day-old and 14-day-old Zhedong white geese in this study.Double antibody sandwich ELISA was used to detect the antibody content at different periods after vaccination.The re-sults showed that:attenuated vaccinated group produced antibodies faster than the other groups,but the antibody con-tent did not last long.The antibody contents of inactivated vaccine+inactivated vaccine(group A,group D)were higher than that of attenuated vaccine(group B,group E)and attenuated vaccine+inactivated vaccine(group C,group F)from day 24th to day 36th after vaccination completion,and the antibodies last longer.According to the results of this study,it is suggested that meat geese can be vaccinated with inactivated vaccine of Tembusu virus disease at 14-day-old,and then vaccinated again 14 days later to obtain higher antibody content.
