摘要
分别将3株鸡传染性喉气管炎病毒(标准强毒株J株、山东分离株N株和L株)经甲醛灭活后制成油乳剂灭活疫苗。免疫效力试验结果表明,以N株鸡传染性喉气管炎病毒制备的油乳剂灭活疫苗免疫效果较其它几种疫苗好,免疫鸡AGP抗体阳性率高达83%,免疫保护率高达100%。
Three infectious laryngotracheitis virus (ILTV) strains(J reference strain, N and L isolated from shandong area) were respectively inactivated with formaldehyde and made into oil-emulsion vaccines, using for immunization of chickens. The results showed that the vaccine with N strain got better immunity effect than others in efficacy test and the immunized chickens had 83% of antibody positive rate by agar gel precipitin test and complete specific protection.
