Pathogenesis of Fumonisin Toxicosis in Swine
Fumonisins are a recently identified group of mycotoxins that are worldwide contaminants of corn produced by Fusarium moniliforme. They induce species-specific disease, including leukoencephalomalacia in horses and pulmonary edema in pigs, but little is known about the pathogenesis of disease. …

Cardiovascular Toxicity Induced by Fumonisin in Pigs and Horses
Fumonisins are a group of mycotoxins produced primarily by the fungus Fusarium verticillioides (formerly F. moniliforme), one of the most prevalent fungi associated with corn intended for human and animal consumption. Since their isolation in the 1988, these toxic fungal metabolites have been shown …

Parameters affecting the production of fumonisin B1 by fusarium verticillioides in culture
… produces a group of mycotoxins known as fumonisins under suitable environmental conditions. A series of studies was designed to provide information regarding some of the factors associated with the production offumonisin B1 (FB1) in maize patties and MYRO liquid medium. Our investigation …

Pathophysiology and Mechanism of Fumonisin B(1) Induced Disruption of Sphingolipid Metabolism
*This dissertation is a compound document (contains both a paper copy and a CD as part of the dissertation).

Inheritance of Resistance to Fusarium Ear Rot and Fumonisin Accumulation in Corn
Fumonisins produced by Fusarium verticillioides ( syn = F. moniliforme) and F. proliferatum have been associated with potentially serious toxicoses of animals and humans. Thus, hybrids with low fumonisin accumulation in grain will be valuable for the production of corn-based human food products. …

The Effect of Iron Overload on the Long-term Toxicological Effects of Fumonisin B1 in Rat Liver
… cancer initiating and promoting properties of fumonisin B1 (FB1) were investigated in male Fisher 344 rats. An initial pilot (dose response) study over 15 weeks was performed to determine a level of dietary iron that achieves a high hepatic iron concentration in the absence of significant side …

The Fumonisin B1-Fed Rat as a model for liver injury, oval Progenitor') cell proliferation, and carcinogenesis
Fumonisin B1 (FB1) is a carcinogenic mycotoxin produced by the fungus Fusarium moniliforme in maize, and is hepatotoxic and hepatocarcinogenic in rats. The goal ofthis dissertation was to characterise the FB1-fed rat as a model for liver injury and carcinogenesis, and to examine the role of oval …

The fumonisin B₁-fed rat as a model for liver injury, oval ('progenitor') cell proliferation, and carcinogenesis
Fumonisin B₁ (FB₁‚ ) is a carcinogenic mycotoxin produced by the fimgus Fusarium moniliforme in maize, and is hepatotoxic and hepatocarcinogenic in rats. The goal of this dissertation was to characterise the FB₁-fed rat as a model for liver injury and carcinogenesis, and to examine the role of oval …

Fumonisins : chromatographic methodology and their role in human and animal health
The fumonisins consist of a group of 7 structurally related mycotoxins originally isolated from Fusarium moniliforme, a fungal contaminant of maize worldwide. The incidence of F. moniliforme in home-grown maize, has been associated with human oesophageal cancer (OC) risk in the Transkei and China. …

Resistance to Fumonisins and Fusarium Ear Rot of Corn
… was to identify sources of resistance to fumonisin contamination and Fusarium ear rot of corn. This research has (i) identified isolates of F. verticillioides and F. proliferatum that produce high levels of fumonisin contamination under field conditions; (ii) adapted an enzyme-linked …

Post-harvest strategies for the prevention of fungal growth and mycotoxin production in corn
… was then evaluated. The relationship between fumonisin production and growth of F. verticillioides and F. proliferatum was then investigated. The research then focused on the evaluation of various preservation techniques. The use of modified atmospheres initially containing high levels of CO2 …

Mycotoxins Risk in Maize Fields in Relation to Insect and Edaphic Factors in South Dakota
… and kernel damage were positively related to fumonisin and aflatoxin concentrations in conventional maize in carbaryl treated and untreated plots. However in Bt maize, only deoxynivalenol concentrations were positively related to caterpillar kernel damage in carbaryl-treated plots. Sap beetle …

Stink bug-Fusarium interactions and mitigation of associated mycotoxin contamination of corn in the mid-Atlantic, U.S.
… stink bug (H. halys) feeding injuries and fumonisin contamination of field corn in the Mid-Atlantic U.S., 2) determine if stink bugs are a vector for mycotoxigenic Fusarium spp. in corn, and 3) evaluate the efficacy of pesticides for mitigating stink bug feeding injury and associated …

Development and validation of a dietary assessment tool to determine dietary intake of people living in oesophageal cancer risk areas in the rural Eastern Cape of South Africa
… known risk factors associated with the cancer is fumonisin exposure (a mycotoxin growing on maize), poor dietary habits and nutrient deficiencies. Little is known about the current dietary habits and nutrient intake of these people, and therefore maize consumption and fumonisins exposure.

Effects of feeding a fumonsin (FB[subscript 2]) naturally contaminated corn at various levels, with and without 2 adsorbents on the growth performance, blood, and liver chemistry of nursery pigs
… of diets containing various concentrations of fumonisin FB1 supplied by naturally contaminated corn with and without 2 adsorbents on nursery pig performance. Use of naturally contaminated corn instead of fumonisin culture material more approximates what would occur under industry conditions. …

Maize ear rot and associated mycotoxins in western Kenya
… in Western Kenya. Deoxynivalenol, zearalenone, fumonisin and aflatoxin were detected in samples collected from the farm and markets in the region. T-2 toxin was absent in all samples collected from the region. The levels of deoxynivalenol and zearalenone detected in the samples ranged from …
