Sporotrichosis in a Pacific white-sided dolphin (Lagenorhynchus obliquidens).

A severe necrotizing granulomatous lymphadenitis caused by Sporothrix schenckii was diagnosed in a Pacific white-sided dolphin (Lagenorhynchus obliquidens) that had been in captivity for about 3 years. Histopathologic and electron microscopic studies, as well as fluorescent antibody techniques, were used to identify S schenckii as the etiologic agent.
