An 11-year-old, castrated male English Springer Spaniel, was presented to Cornell's Internal Medicine service for evaluation a cough of at least four years' duration. The cough was described as dry, non-productive, with a frequency and severity that had remained static over the past four years. Mucopurulent bilateral nasal discharge accompanied the cough, which was described as being worse in the spring and summer months. Blood work (hematology and chemistry), chest radiographs, fecal flotation, and airway sampling were performed in an effo1i to determine the cause of the chronic cough. Endotracheal wash revealed neutrophilic inflammation with intra-lesional fungal organism confinning a diagnosis of fungal bronchitis. Fungal culture and sensitivity were performed and revealed infection with Conidiobolus spp. Further fungal species identification was not possible. This paper will evaluate the process of diagnosing and treating Conidiobolus spp. in this patient, as well as review current human an animal literature regarding Conidiobolomycosis.
