Avian pox in ostriches.
Nodular cutaneous and diphtheric oral lesions, resembling avian pox were observed in 2 flocks of young ostrich chicks. Typical eosinophilic intracytoplasmic inclusion bodies were seen in histological sections and a pox virus was isolated from the lesions. A commercial fowl pox vaccine was used to protect young ostriches in the field.
