Concomitant Vitamin A Deficiency Following Suspected Fowl pox virus Infection Leading to Esophageal Gland Metaplasia in a Layer Flock
Abstract:
The present communication pertains to an incidental occurrence of concomitant vitamin A defeciency and fowl pox infection in a layer flock. The lesions were characterized by typical presence of pustule like eruptions in cranial part of esophageal mucosa and histologically with metaplastic and keratotic glands with distinctly evident intracytoplasmic inclusion bodies within few intact epithelial cells. Specialized staining techniques i.e. Triple shorr’s confirmed its presence at palatine mucosal gland, esophageal gland and tracheal epithelium. To author’s knowledge, the evidence of eosinophilic intracytoplasmic inclusion bodies deeply within tracheal epithelial surface is rare and one of the few histologically documented case where unusual location of inclusion bodies at splanchanic surface was described, in addition to the description of vitamin A defeciency with accelerated, pre-altered tissue morphology preceded by fowl pox virus infection.
