Abstract |
Studies were undertaken to determine the presence of lesions and immuno-fluorescent (IF) antigen of Marek's disease (MD) in the comb, wattles and skin overlaying the shank of MD affected birds. Lesions were more common in the comb than in the wattles and shanks, and were characterized by degeneration of epithelial lining cells and accumulation of lympho-reticular cells around the blood vessels of the dermis. Diffuse infiltration of these cells replacing varialbe areas of dermis were also seen in some cases. Immunofluorescent antigen was mostly confined to epidermal epithelium and was detected in comb from majority of cases, and the frequency of detection of IF antigen was similar to the presence of MD lesions in these tissues. This study indicates that the presence of lesions and viral antigen (If) of MD in these cutaneous appendages might play a significant role in epidemiology and diagnosis of this disease.
