title: Tyzzer's disease in a neonatal cockatiel.
abstract: A 4-day-old cockatiel that died suddenly had a pale, mottled liver at necropsy. Extensive necrosis and numerous bacilli were present microscopically in the liver. The organism was identified as Bacillus piliformis, the causative agent of Tyzzer's disease, by special staining and electron microscopy. This is the first report of Tyzzer's disease in an avian species.
