摘　　要：本试验用从广西分离的二株引起鸡传染性鼻炎的副鸡嗜血杆菌 ( H aemophilus paragallinarum,H.pg) GX 97、GX 981株研制成自家油乳苗 ,进行后备鸡免疫试验 ,免疫后 3、 6、 9和 1 2个月进行免疫抗体检测和攻毒试验。结果表明 ,免疫后 6个月 90 %免疫鸡的抗体滴度在 1∶ 640以上 ,9个月抽样攻毒有 75%～ 80 %的鸡获得保护。大田免疫试验也获得了良好的效果。证明自家油乳苗免疫接种也是防制该病的一个有效途径。In this study we had developed an oil-emulsion vaccine ofinfectious coryza (IC) using two Haemophilus paragallinarum (H.pg) strains, GX-97 and GX-98-1, which was isolated from Guangxi chicken farms. The oil-emulsion vaccine was used to vaccinate chickens. In 3, 6, 9 and 12 months postvaccination the antibody respon se of chickens vaccinated was detected and immune preventive test was carried out by challenging a reference strain C1-95-11. As the result, antibody titers of 90% chickens vaccinated remains at least 1∶640 in 6 months postvaccination. The results of chal-lenge test indicated that 75%～80% chickens vaccinated were prot ected against reference strain C1-95-11 in 6 months after vac cination. The field vaccination test showed a very good immunity effect. The vaccination of oil-emulsion vaccine of IC was proved to be an effective way to prevent and control IC.
