of 50 birds of five different flocksaffected
with avian encephalomyelitis. Birds showed
signs like opacification of cornea, tremor, leg
weakness, reduced feed and water intake, drop
in egg production and death. Twenty two out of
50 serum samples showed increased antibody
titres for avian encephalomyelitis virus.The
affected birds did not show any gross lesions at
necropsy. Microscopically eyes showed degeneration
and coagulation of lensprotein with
mononuclear cell infiltration. Brain revealed
gliosis, central chromatolysis, neuronal degeneration
and perivascular cuffing.Proventriculus,
gizzard and panc reatic islets showed lymphocyticinfiltrations.
