Avian neoplastic diseases were investigated in 17 AA broiler breeder farms in Shandong area with serology, histopathology, immunohistochemistry and PCR detections. Serologic test results showed that the antigen positive rate of Marek's disease virus (MDV), antibody positive rate of avian leukosis virus subgroup J (ALV-J) and reticuloendotheliosis virus (REV) were 1.87%, 9.52%, and 39.78%, respectively. Double and triple infection, MDV+ALV-J, REV+MDV, REV+ALV-J, and MDV+REV+ALV-J were 1.12%, 1.21%, 3.92%, and 0.65% The histopathological observation indicated that single and dual tumor focal caused by these viruses were seen in visceral organs. Immunohistochemical test showed that MDV, ALV-J, and REV antigen positive rate were 38.6%, 54.39%, and 28.07%. PCR detection results of MDV and ALV-J indicated that there still has high infective rate of the three tumor pathogens in Shandong area.
