In Vitro Metabolism of Fumonisin B1 by Ruminal Microflora

Veterinary Research Communications, 2000
Fumonisin B1 (FB1) is a mycotoxin produced by Fusarium moniliforme and F. proliferatum. Little is known of its metabolic fate after oral ingestion in ruminants, but these animals are reported to be tolerant towards FB1. The metabolism of this mycotoxin was evaluated following incubation (1 microg/ml) in ruminal fluid for up to 72 h, in the presence or ...

Synthesis of analogs of fumonisin B1

Journal of Agricultural and Food Chemistry, 1992
The fungus Fusarium moniliforme Sheldon is one of the most important ear rot pathogens of corn (Nyvall, 1983). The toxicity of the mold was initially discovered when an isolate of F. moniliforme from corn grown in an area of Africa with a high incidence of esophageal cancer was tested (Marasas et al., 1981).

Hydrolyzed fumonisin B1 induces less inflammatory responses than fumonisin B1 in the co-culture model of porcine intestinal epithelial and immune cells.

Toxicology Letters, 2019
Fumonisin B1 (FB1), mainly produced by Fusarium verticillioides and Fusarium proliferatum, can be converted to the less toxic metabolite hydrolyzed FB1 (HFB1) by enzymatic degradation.

Initial studies on the toxicokinetics of fumonisin B1 in rats

Food and Chemical Toxicology, 1992
Fumonisin B1 (FB1), the major compound in the fumonisin group of secondary metabolites of Fusarium moniliforme Sheldon, is associated with some human and animal diseases. After intraperitoneal dosing to rats (7.5 mg/kg), FB1 was rapidly absorbed and reached a maximum concentration in plasma within 20 min after injection.

Occurrence of fumonisin B1 in maize imported into Taiwan

International Journal of Food Microbiology, 2001
Samples of maize imported into Taiwan during 1997-1998 were collected and analyzed for the presence of fumonisin B1 (FB1) using high performance liquid chromatography. Eight (6.8%) of 118 samples were found to contain FB1 (334-1614 microg kg(-1)). The frequency of FB1 found in maize samples imported from Australia was 20%, followed by Thailand (10 ...

Determination of Fumonisin B1 in maize using molecularly imprinted polymer nanoparticles-based assay.

Food Chemistry, 2019
Fumonisin B1 (FB1) is a carcinogenic mycotoxin produced by Fusarium species contaminating maize. At present, fumonisin determination is performed using costly and demanding chromatography techniques or immunoassays.

Biliary excretion of the mycotoxin fumonisin B1 in rats

Food and Chemical Toxicology, 1994
The biliary excretion of the mycotoxin fumonisin B1 (FB1), produced by the fungus Fusarium moniliforme Sheldon, has been measured in male Wistar rats. After ip injection of a solution of FB1 (7.5 mg/kg body weight), 67% of the applied dose was recovered in bile over a 24-hr period, 88% of this recovery being excreted in the first 4 hr after dosing.

A lateral flow assay for simultaneous detection of Deoxynivalenol, Fumonisin B1 and Aflatoxin B1

Toxicon, 2018
&NA; Deoxynivalenol (DON), Fumonisin B1 (FB1) and Aflatoxin B1 (AFB1) have strong toxicity to humans and exist widely in grain and food. It is necessary to screen these mycotoxins to guarantee food safety.

Antinutritional effects of fumonisin B1 and pathophysiological consequences

Toxicology Letters, 2003
Due to its structural similarity with sphingosine, fumonisin B(1) (FB(1)) inhibits ceramide synthase (a key enzyme of sphingolipid biosynthesis) leading to an intracellular accumulation of sphingoid bases with a consequent increase of sphinganine/sphingosine (SA/SO) ratio. In adult male rats, dietary exposure to fumonisin induces a significant increase

Residue formation of fumonisin B1 in porcine tissues

Food Additives and Contaminants, 2003
The residues derived from the uptake of fumonisin B1, a toxic metabolite of Fusarium verticillioides frequently occurring in corn and corn products, were determined in growing pigs. After oral administration of 100 mg FB(1)/animal/day for 5-11 days, serum, bile, lung, liver, kidney, brain, spleen, pancreas, heart, muscle, eye, and fat samples were ...
