[Ataxia and paralysis in meat chickens, as a result of an infection with avian encephalomyelitis virus in the breeding flock].
An outbreak of avian encephalomyelitis (AE) in 7 broiler flocks, with signs of ataxia and paralysis is reported. The diagnosis was made by immunofluorescence, histopathology and virus isolation. The breeding flock had a temporary drop in egg production and reduced hatchability caused by late embryonic mortality. The breeding flock had not been vaccinated against AE. The problems were probably caused by vertical transmission of AE virus.
