Abstract:
A total of 60 spp. of fungi (of which 13 had not been reported before) representing 34 genera was isolated from 39 samples of feed examined. The spp. and their frequency of isolation are tabulated. The fungi most frequently encountered were: Aspergillus flavus, A. nidulans, A. niger, Cladosporium sp., Fusarium moniliforme [Gibberella fujikuroi], Hormodendrum sp., Rhizopus stolonifer, and Trichoderma viride. A. flavus was present in a viable state in 16 of the 39 feed samples, but aflatoxin could be detected chemically in only 5 of them. In 3 samples, in which aflatoxin was detected, A. flavus did not appear among the fungi isolated. Of 18 samples fed to experimental animals none produced symptoms of toxicity, although aflatoxin was present in 2 of them.
