The type B trichothecene mycotoxins deoxynivalenol (DON), nivalenol (NIV) and fusarenon-X (FX) are structurally related secondary metabolites frequently produced by Fusarium on wheat. Consequently, DON, NIV and FX contaminate wheat dusts, exposing grain workers to toxins by inhalation. Those trichothecenes at low, relevant, exposition concentrations have differential effects on intestinal cells...

background: mycotoxins are a group of structurally diverse substances produced by a wide range of moulds. these fungal secondary metabolites, whose presence in feed is unavoidable, can impose hazards to human and animal health. continuous concern about potential effects of mycotoxins in the human diet has led to an increasing interest in researches about fungi and mycotoxin production. the aim ...

Today, much attention has been directed to the dangers associated with stealth infections with little attention being directed toward the diverse mechanisms by which mycotoxins affect nerve action, cause immunosuppression, and may contribute as a co-factor in Alzheimer's disease and other neurodegenerative disorders. Mycotoxins are secondary toxic metabolites produced by many species of fungi t...

It has recently been demonstrated that patients who develop chronic illness after prior exposure to water damaged buildings (WDB) and mold have the presence of mycotoxins, which can be detected in the urine. We hypothesized that the mold may be harbored internally and continue to release and/or produce mycotoxins which contribute to ongoing chronic illness. The sinuses are the most likely candi...

A total of 84 medicinal plant samples and spices were examined for the contamination of molds and mycotoxins. Ten fungal genera of different taxonomic groups were detected. Aspergillus flavus, A. parasiticus, A. niger, Fusarium oxysporum, and Penicillium viridicatum occurred most often on the medicinal plant samples. Direct determination of mycotoxins in medicinal plant samples revealed aflatox...

The fungal genus Aspergillus was established in 1729, and includes species that are adapted to a wide range of environmental conditions. Many aspergilli produce mycotoxins in foods that may be toxic, mutagenic or carcinogenic in animals. Most of the Aspergillus species are soil fungi or saprophytes but some are capable of causing decay in storage, disease in plants or invasive disease in humans...

Mycotoxins are toxic secondary metabolites produced by fungi in the field or during storage; these fungi are mainly saprophytic molds growing on foodstuffs or animal feeds. These molds produce chemical compounds of low molecular weight that are not detected by antigens and hence are insidious poisons with no obvious symptoms. Since 1960, mycotoxins have been considered responsible for diseases ...
