[Mycotoxins of Fusarium spp. in rotten fruits from Cucurbita ficifolia].

Swine acute toxicosis with hemorrhages was recognized after feeding on decayed chayotes (C. ficifolia fruits). In order to elucidate the origin of this pathology, chayotes spoiled by fusaria were analyzed. The mycotoxins (T-2 toxin, fusarenon X) identified in decayed chayotes, the mice alterations and the isolated species (F. equiseli, F. graminearum, F. heterosporum, F. sambucinum var. coeruleum and F. solani), suggest that the effects on swine may be due to trichothecenes produced by fusaria within fruits, and that eating damaged chayotes is dangerous for animals.
