Detailed Explanation of the Pathological Lesions of Chicken Infectious Anemia
The most characteristic necropsy lesion of uncomplicated chicken infectious anemia is bone marrow atrophy. The bone marrow of the femur is fatty-colored, pale yellow, or pink; the thymus is atrophied and congested, and in severe cases may undergo complete involution. As the age of affected chickens increases, thymic atrophy is more readily observed than bone marrow lesions. Bursal atrophy is not obvious and is often transient; sometimes the weight is reduced and the volume is decreased, while in most affected chickens the bursa of Fabricius appears semi-transparent. In severely affected cases, the liver and kidneys may be seen to be enlarged, yellowed, and friable.
