PROVENTRICULAR PATHOLOGIES WITH GENERALISED TUBERCULOSIS IN PEAFOWL (PAVO CRISTATUS): PATHOMORPHOLOGICAL ANALYSIS

The results of pathological anatomical changes in the proventriculus of a decorative peacock that died from tuberculosis were described in this article. Mixed chronic destructive multifocal ulcerative panproventriculitis with a predominance of ulcerative component without signs of healing was diagnosed. Absence of epithelialization of large ulcer and relief in this area is a sign of malignancy. Complicating pathologies were classified: rupture of proventriculus wall, hemorrhage, atrophy of glands of mucous membranes, cicatrization, deformity. Proventricular component in the pathomorphosis of ornamental peacock tuberculosis is an accessible and convenient target for the diagnostician and can significantly supplement the pathomorphological criteria used to decipher the variants of avian tuberculosis course. The severity of damage to the glandular stomach in peacocks is due to the tropism of tuberculosis pathogens to the lymphoid structures located here.

Automated summary

This article describes the results of pathological anatomical changes in the proventriculus of a decorative peacock that died from tuberculosis, diagnosing it with mixed chronic destructive multifocal ulcerative panproventriculitis. The absence of epithelialization and relief in the ulcerative area was recognized as a sign of malignancy, which is important for diagnosis and understanding of avian tuberculosis.
