J亚型禽白血病病毒感染黄鸡病毒血症和抗体反应动态的研究
Research of Dynamics of Viremia and Antibody Responses of Yellow Chicken Infected by Avian Leukosis Virus Subgroup J
摘要
Abstract
The dynamics of viremia.ALV-J antibody response in yellow chickens and p27 antigen shedding in cloacal swabs were examined respectively after the 11-day-old yellow chicken embryos were inoculated with hemangioma related ALV-J SCAU-HN06 isolate via allantoic cavity. The results showed that viremia could be detected as early as 1 week post hatch,there was a viremia peak at 7 week,and the positive rate of viremia remained more than 80% continuously since 9 week. ALV-J antibody response could be detected as early as 6 week by ELISA.the positive rate of antibody was no more than 33. 3% during the trial. The positive rate of p27 antigen in cloacal shedding rised quickly, reached peak at 3 week, then kept at high level. The study suggested that ALV-J isolate infection via egg inoculation could result in persistent viremia and immunotoleranee. The study provided the basis for ALV-J control and eradication in yellow chickens.关键词
