摘要

Epizootic ulcerative syndromes have been reported with increasing frequency in fish from many parts of the world, including the east coast of the United States. Etiology is uncertain for many outbreaks, although viruses, bacteria, fungi, and other pathogens have been proposed in specific geographic locations. Environmental stress, often as a consequence of pollution, has also been implicated in at least some of the reported epizootics. The ulcerative lesions do not constitute a single disease entity, since their characteristics may be quite different in different host species and areas. Such lesions can be considered as generalized responses of fish to infection and/or abnormal environmental conditions. Types of ulcerations have been described, some with several developmental stages, and mortalities have been observed in some outbreaks.
