Toxicological interactions between mycotoxins
Résumé
Humans and animals are exposed to several toxins at the same time. The toxicity of combinations of mycotoxins cannot always be predicted based upon their individual toxicities. Interactions between concomitantly occurring mycotoxins can be antagonistic, additive, or synergistic. Several approaches have been used to determine the interaction between mycotoxins. The theoretical biology-based models of additivity, especially the Chou-Talalaymethod, are the most advanced. Using this latter model in several cellular systems and in an ex vivo intestinal explants system, we have observed a synergistic toxicity for trichothecenes, especially at low concentrations. The synergistic effects observed after exposure to a mixture of low concentrations of mycotoxins could pose a significant threat to public health.
