Chronic cutaneous candidiasis in bottle-nosed dolphins.

In a 20-month period, generalized chronic cutaneous candidiasis developed in 3 performing bottle-nosed dolphins kept in an indoor pool. Extensive esophagogastric ulcerations were observed in 2 of the dolphins, each of which died, presumably because of these lesions. The 3rd dolphin died during a surgical procedure and did not have any esophagogastric ulcerations. Candida albicans was the only organism isolated from skin lesions but was not isolated from adjacent normal skin of dolphins. Treatment with antifungal drugs was unsuccessful. Subsequently, immunopotentiating treatment with levamisole phosphate resulted in formation of granulation tissue and healing of the skin lesions.
