| 摘 要： | 本文对大肠杆菌灭活菌苗的免疫原性、免疫鸭的外周血液免疫动态及卵黄凝集抗体的测定进行了研究。结果表明,菌苗对小白鼠、可疑感染鸭和健康鸭具有良好免疫原性,鸭的免疫期达4—5个月,可提高种鸭产蛋率和种蛋孵化率。鸭只免疫后45天平均凝集抗体滴度达270.4和313.6,免疫后5个月仍有62.5％鸭只的凝集抗体滴度≥40。免疫鸭血清r-球蛋白含量显著(P<0.05)或极显著(P<0.01),高于非免疫鸭。

| Abstract: | The immunogenity of E.coli vaccine,increase and decrease of agglutin-antibody and gamma-glublin in sera of vaccinated duck,and a method to detect the agglutin-antibody in the yolk from the vaccinated ducks wers studied.The results indicated the strain is safe and invirulence to breeding ducks and the suspiciously infected ducks. The vaccinated ducks are not sensitive to virulence homologous E.coli strain for 4—5 monthes.The vaccinated ducks can increase the production of breeding eggs.Among the vaccinated ducks,agglutin-antibody mean titers reached as high as 270. 4 and 313. 6 after 45 days. The amounts of gamma-glublin was significantly higher in vaccinated ducks than unvaccinated ducks (P<0.05or P<0.0l).The agglutim-antibody in the yolk could be detected with the tube agglutination test. |
