摘要
本研究用司本—８０和硬脂酸铝加入白油为油相，吐温—８０加入灭活的副鸡嗜血杆菌液为水相，制备成油乳剂苗．该苗属油包水类型，４℃放置６个月稳定，５倍量接种产蛋鸡，结果无不良反应。该苗免疫鸡群后一个月，其凝集抗体效价为１：６４～１：１２８，攻毒保护率为１００％，免疫期６个月．
The oil-emulsion vaccine was developed by mixing the oil phase with the aqueous phase in a proper proportion, the oil phase was Span-80 and Alumium atearate and the aqueous phase was a mixure which contained the antigen inactivated by formalin and Tween-80. Keeps entirely oil-emulsified and effective for 6 months at 4℃, the vaccine was found no side-effects to layers inoculated by five doses. The immune responses of layers were determined by microagglutination test. The antibody titre against the vaccine was 1: 64 -1: 128 one month after inoculation. The protect rate challenged with virulent Haemophilus paragallinarum was 100% and the protection can last for 6 months.
