|a5= AE causes the most serious disease in chicks under 3 weeks of age. The clinical signs for this age group are:
*Electron miscroscopy
*neurological signs ranging from ataxia, rapid tremor of the head and neck, drooping of the wings, weakness, paralysis, exercise intolerance to blindness and changes in vocalisation.
*Staining with fluorescent labelled antisera
*Weight loss, lameness, and unthriftiness
*Affected chicks sit on their hocks, and cannot move well and many fall over onto their sides
Laying hens rarely show clinical signs but the virus causes:
*Temporary reduction (2 weeks) in egg production
*Decrease in droppings
*Decrease in hatching rates

|q6= Against which two adenoviruses are vaccines available?
|q6= How can AE be diagnosed?

*EDS
The following methods have been used to help diagnose Avian Encephalomyelitis (AE):
*HE
*Virus Neutralization test
|l6= Avian Adenoviruses#Treatment and Control
*Agar Gel test
*Embryo Susceptibility test
*Elisa test
All of the above tests indicate exposure to AE but not neccessarily a current infection.
Diagnosis can be achieved confirmed by either histopathology or by virus isolation.
Post mortem and identification of pathognomonic lesions in the:
*Midbrain and rotundua and ovidalis nucleus (microglisosis)
*Proventriculus (dense nodules within the muscular wall) * Lesions can also be present in the pancreas
