Isolation and sequence-based identification of Oxyporus corticola from a dog with generalized lymphadenopathy

The present case report describes isolation of the fungus Oxyporus corticola from multiple lymphocutaneous tissues of a Beagle dog. Until recently, this fungus had not been reported in the human or veterinary medical literature as a cause of animal disease. A single previous report also involved infection in a German Shepherd Dog, a breed with reported increased susceptibility to disseminated fungal infection and dysfunctional immune response. Isolates were non-sporulating and required molecular identification methods for prompt differentiation from other fungal pathogens. Risk factors for infection with O. corticola are unknown.
