Abstract: In order to study the effect of different test materials on the detected results of avian leukosis virus (ALV)-p27 antigen by ELISA, the cloacal swabs ALV-p27 antigen were detected by ELISA in 180-day local breeds hen, and the parts of the positive and negative chicken was selected to group test, the serum, egg whites and cell supernatant ALV-p27 antigen were detected by ELISA, the specific genes of ALV were detected by RT-PCR in blood.The results showed that serum, egg white and cell supernatant as ELISA test materials, the positive rate lower of than cloacal swabs, and serum ALV-p27 positive samples include all egg whites and cell supernatant positive samples in positive group.It was a significant correlation between ELISAs with serum and cell supernatant (linear equation:Y=1.8439X-0.1469, the correl was 0.937).In positive group, ALV-p27 gene positive rate lower than cloacal swabs ELISA, but higher than the serum, egg and cell culture medium, and ALV-p27 gene positive samples include serum positive samples by ELISA.ALV-J gp85 gene positive rate of 29.17%, and all positive samples were included in the serum ALV-p27 positive samples.The results suggested that the cloacal swabs as test material may occur false positive results, and egg whites and cell supernatant may occur undetected by ELISA ALV-p27 antigen assay in adult chicken, serum as test material in ELISA could more accurately reflect the state of adult chickens infected with ALV.

Key words: avian leukosis virus; ALV-p27 antigen; ELISA; test materials
