Conidiobolomycosis in goats

Abstract

ABSTRACT: The present article presents cases of conidiobolomycosis in adult goats with clinical signs characterized by serous nasal discharge, dyspnea, apathy, and weight loss. Two goats were necropsied. Necropsy displayed increased volume on the sagittal section of the head and an ulcerated surface containing a yellow friable mass with irregular and granular consistency in the nasal septum and in the ventral nasal turbinate. One goat also presented lesions on the ear’s skin and the right pelvic limb. Microscopically, lesions were characterized by multifocal granulomas with a central necrotic area containing non-stained fungal hyphae images surrounded by a granulomatous infiltrate. Samples of the lesions examined by immunohistochemistry and polymerase chain reaction were positive for Conidiobolus lamprauges. This is the first report of conidiobolomycosis in goats, and the disease should be considered in the differential diagnoses for rhinitis and dermatitis in goats.
