This study describes a case of histomoniasis in an Indian peafowl (Pavo cristatus) associated with coinfection by Aspergillus spp. The bird, raised in an environment shared with other gallinaceous species, presented clinical signs of apathy, hyporexia, and progressive weight loss, eventually progressing to death. The anatomopathological examination revealed necrotizing granulomatous hepatitis, fibrinonecrotic typhlitis, and necrotizing heterophilic pneumonia, with the presence of septate hyphae compatible with Aspergillus spp. and trophozoites of Histomonas meleagridis in the cecum. The findings indicate a fungal coinfection, potentiated by predisposing factors such as immunosuppression and unfavorable environmental conditions. This case report highlights the importance of differential diagnosis in ornamental birds and reinforces the need for appropriate sanitary management to prevent complex infectious diseases in exotic species.
