Problem statements: Fumonisin was a mycotoxin produced mainly by fungi belonging to the genus Fusarium in various foods and feeds. They occurred worldwide and were found predominantly in corn and in corn-based animal feeds and also can be found in other crops. Contamination of food and feed with fumonisins has been implicated in and associated with a number of diseases in both livestock as well...

Sixty samples of corn from both conventional and organic farms were tested for internal fungal contamination. Molds were identified to genus, and those belonging to the genus Fusarium were identified to species. Twenty isolates of Fusarium verticillioides were tested with a high-performance liquid chromatography-naphthalene dicarboxaldehyde-fluorescence method for their ability to produce fumon...

objective(s):fumonisins are a group of toxic and carcinogenic mycotoxins, which contaminate the grains and their products. the aim of this study was to examine the apoptotic and proliferative activity of mouse gastric mucosa following administration of fumonisin b1 (fb1).    materials and methods: twenty-nine female mice divided into treatment (n=15) and control (n=14) groups. the treatment gro...

Fumonisin B1 (FB1) is the most abundant of the fumonisin mycotoxins, mainly produced in corn by fungi of the genus Fusarium. FB1 has been shown to be hepatocarcinogenic and nephrocarcinogenic in animals. Contamination of corn with FB1 was assayed in samples collected from Mazandaran Province, situated on the Caspian littoral of Iran, in September 2000. In this survey, 38 corn samples were analy...

Fumonisin B1(FB1) is a fungal metabolite of Fusarium verticillioides (= F. moniliforme), a fungus that grows on many crops worldwide. Previous studies demonstrated that male BD IX rats consuming diets containing 50 ppm fumonisin B1 developed hepatocellular carcinomas. In our recent studies, diets containing FB1 at 50 ppm or higher concentrations induced renal tubule carcinomas in male F344/N/Nc...

Approximately 200 samples of rice (including white, brown, red, black, basmati and jasmine, as well as wild rice) from several different countries, including the United States, Canada, Pakistan, India and Thailand, were analysed for aflatoxins, ochratoxin A (OTA) and fumonisins by separate liquid chromatographic methods in two different years. The mean concentrations for aflatoxin B(1) (AFB(1))...

The aim of the study was to determine the mycobiota and natural levels of mycotoxins such as aflatoxin B1 (AFB1), ochratoxin A (OTA), fumonisin B1 (FB1), and deoxynivalenol (DON) present in brewers grains pre- and poststored intended for bovine intensive rearing. Poststored (80%) samples had counts higher than 1 × 10(4) colony-forming units (CFU/g). Cladosporium spp. and Aspergillus spp. were i...

Fumonisins are inhibitors of the biosynthesis of sphingosine and more complex sphingolipids. In eucaryotic cells, fumonisin inhibition of sphingolipid biosynthesis is a result of inhibition of the enzyme ceramide synthase. Large increase in free sphinganine concentration in plant and animal cells are observed within a few hours after exposure to fumonisins and/or Alternaria toxins (AAL-toxins)....

Forty-seven corn samples were collected in 1989 from Linxian and Shangqiu Counties in Henan Province, the high- and low-risk areas, respectively, for human esophageal cancer in the People's Republic of China. The samples were analyzed for fumonisin (fumonisin B1 [FB1] and FB2) contamination. Of the fumonisin-positive samples, the mean levels in Linxian corn were found to be 872 ng/g for FB1 and...
