Clinical Signs and Diagnosis
Clinical signs include a pale comb, wattle, eyelids, legs and carcass, anorexia, weakness, stunting, unthriftiness, weight loss, cyanosis, petechiation and ecchymoses, lethargy and sudden death. Neurological signs include dullness, depression and paresis. Subclinical infection my cause reduced growth rates and other health problems.
A presumptive diagnosis can be made based on the clinical signs and a low haematocrit reading (<27%). Virus isolation, increased antibody titres, immunoperoxidase staining, ELISA, PCR or indirect immunofluorescence can be used to confirm the presence of the virus. Post mortem finding should show significant atrophy of the lymphoid organs, haemorrhage throughout the tissues and pale watery bone marrow.
