| Popis: | Dermatitis with intradermal cilated protozoa was identified in 18 of 95 (19%) Atlantic Bottlenose Dolphins ( Tursiops truncatus) that died during the 1987–1988 Atlantic-dolphin morbillivirus epizootic. The lesions were characterized by focally extensive suppurative and histiocytic dermatitis and cellulitis with ulceration and variable numbers of dermal and hypodermal ciliates. Vasculitis, thrombosis, and/or intravascular ciliates were rarely present. In one dolphin, there was an associated lymphadenitis with ciliates, and in another, bronchopneumonia with rare intrabronchiolar ciliates. Ten of the dolphins were female, and eight were male. The animals ranged in length from 148 to 260 cm. Eleven were from Virginia, four were from New Jersey, and three were from Florida. In 13 dolphins, results of immunohistochemical and/or polymerase chain reaction (PCR) tests were positive for morbillivirus infection. Results of immunohistochemical tests were negative in four dolphins that were not also tested with PCR. Results were also negative in one dolphin tested using both methods. Nine dolphins had concomitant bacterial, fungal, and/or other protozoal infections. Fourteen other dolphins with ciliate-associated dermatitis were identified from 414 Atlantic bottlenose dolphin cases (3%) archived at the Armed Forces Institute of Pathology. The incidence of dermatitis with invasive ciliates is much greater in dolphins that died during the 1987–1988 epizootic. |
