|a1=Avian encephalomyelitis-like virus 1 (AEV).

|q2= Is ''avian encephalomyelitis virus'' (AEV) a RNA or DNA virus?
|q2= Is avian encephalomyelitis virus (AEV) an RNA or DNA virus?
|a2= AEV is a single stranded RNA (ssRNA) virus

*Horizontally via faecal-oral route (main route of infection)

*Vertical transmission from infected layer to their chicks
*Vertical transmission from infected layer to their chicks
*The virus replicates in the epithial cells of the alimentary tract and is circulated in the bloodstream to other organs and the central nervous system (CNS). The virus is shed within 3 days of oral ingestion and in young chicks can continue to be shed for over two weeks. Shedding ceases once specific antibody's are produced.

*Elisa test

All of the above tests indicate exposure to AE but not neccessarily a current infection.
All of the above tests indicate exposure to AE but not neccessarily a current infection.
Diagnosis can be confirmed by either histopathology or by virus isolation.

|q10=What is the distribution of AE?

|q14=How can AE be controlled?
|q14=How can AE be controlled?
|a14=Vaccination of pullets several weeks before they come into lay. Vaccination protects the flock from a reduction in egg production and prevents vertical transmission of the virus to chicks by providing the chicks with a sufficient level of maternal derived antibodies. There are live and attenuated vaccinations available which can be administered in drinking water or as an eye drop, the latter being more effective.
