First isolation of Prototheca bovis from a bottlenose dolphin (Tursiops truncatus)

To our knowledge, this is the first report of <i>Prototheca</i> sp. isolated from the digestive tract of a dolphin. A captive-born female bottlenose dolphin (<i>Tursiops truncatus</i>) weighing 165 kg that was housed at Enoshima Aquarium presented with a slightly elevated body temperature and candida-like yeasts in stomach fluid and feces. Gastroscopy revealed cobblestone-like thickening of the mucosa with a few ulcers in the forestomach. <i>Prototheca bovis</i> was isolated from the biopsy specimen of the lesion.
