Wheat grains are well known to be invaded by Fusarium spp. under field and storage conditions and contaminated with fumonisins. Therefore, determining Fusarium spp. and fumonisins in wheat grains is of prime importance to develop suitable management strategies and to minimize risk. Eighty-two stored wheat samples produced in Iran were collected from various supermarkets and tested for the prese...

A variety of toxic secondary metabolites including fumonisins, can be produced by the fungus Fusarium moniliforme and closely related species in section Liseola in large amounts (g/kg in laboratory cultures). Underivatized fumonisins were detected by HPLC using either an evaporative light scattering detector or electrospray MS. Electrospray MS used together with NMR and GC/MS was used to identi...

Mold-produced toxins have tainted food crops probably since the beginnings of agriculture. These mycotoxins can occur when certain molds infect food crops before or after harvest. Both humans and animals are vulnerable to poisoning through consumption of contaminated foods, with acute or chronic illness—including cancer—a potential result. A study by Paul K. Chelule of the University of Natal i...

The absolute stereochemical description of fumonisin B1 (FB1) and presumably of its congeners is now secure. In this article I summarize studies leading to this conclusion and outline the biosynthetic and synthetic studies of FB1.

Fusarium moniliforme (F. moniliforme) is one of the most frequent fungal pathogens found in rice. Samples of rice grown in three different zones of Mazandaran Province, Iran were collected and analyzed for the presence of fumonisin B (FB ). Mycological analysis revealed the presence of F. moniliforme-type isolates 1 1 in 65.1% of the rice samples. Average levels of FB per zones 1, 2 and 3 were ...

This article describes clinical, etiologic and pathologic diagnosis of an outbreak of equine leukoencephalomalacia. Two samples of the corn consumed by the affected horses contained fumonisin B 1 at levels of 46 and 53 μg/g and Fusarium moniliforme, a good in vitro mycotoxin producer.

Contamination of animal and poultry feeds by Fusarium and the mycotoxin Fumonisin B1 is frequent in the feed supply chain. The present study evaluated the prevalence of fumonisin B1 producing Fusarium among irradiated and non-irradiated animal and poultry feed mixtures. Further, the efficiency of γ-rays (2.5, 5.0, 7.5, and 10.0 kGy) to minimize Fusarium growth and biosynthesis of fumonisin B1 i...

A high-resolution liquid chromatography-Orbitrap mass spectrometry (LC-Orbitrap MS) method was developed for simultaneous determination of 20 Fusarium toxins (nivalenol, fusarenon-X, deoxynivalenol, 3-acetyl deoxynivalenol, 15-acetyl deoxynivalenol, HT-2 toxin, T-2 toxin, neosolaniol, diacetoxyscirpenol, fumonisin B1, fumonisin B2, fumonisin B3, fumonisin A1, fumonisin A2, fumonisin A3, zearale...

background : numerous epidemiologic studies have shown that esophagus cancer is more common in areas with grains containing mycotoxin such as fumonisin b1 (fb1). the aim of this research is to study the effect of long- and short-term of esophagus tissue to fb1 orally administered in animal model. materials and methods : forty-four female mice have been divided in two short- and long-term groups...
