Publikováno v: Molecular plant pathology. 2(4)

Summary Isolates of Fusarium subglutinans mating population E are usually found on maize. This fungus forms part of the so-called Gibberella fujikuroi species complex. Previously, F. subglutinans has been associated with two additional mating populat

Publikováno v: Carcinogenesis. 21(8)

Fumonisin B(1) (FB(1)) is a worldwide corn contaminant and has been epidemiologically linked to the high incidence of human esophageal cancer in South Africa and China. FB(1) is hepatocarcinogenic in rats by an unknown mechanism. Inhibition of cerami

Fusarium species from plant debris associated with soils from maize production areas in the Transkei region of South Africa

Autor: J P, Rheeder, W F, Marasas

Publikováno v: Mycopathologia. 143(2)

Fusarium species were isolated from plant debris in soil samples collected from cultivated maize fields and from undisturbed grasslands in two areas of the Transkei region. A total of 1205 Fusarium isolates were recovered from 27 soil samples. Fiftee

Publikováno v: International journal of cancer. 78(5)

Squamous cell carcinoma of the esophagus has an uneven geographic distribution, with a high incidence in the Transkei region of Eastern Cape Province, South Africa. The precise molecular events associated with tumorigenesis of esophageal cancer in th

Hepatotoxicity and -carcinogenicity of the fumonisins in rats. A review regarding mechanistic implications for establishing risk in humans

Autor: W C, Gelderblom, S D, Snyman, S, Abel, S, Lebepe-Mazur, C M, Smuts, L, Van der Westhuizen, W F, Marasas, T C, Victor, S, Knasmüller, W, Huber

Publikováno v: Advances in experimental medicine and biology. 392

Cancer induction by the non-genotoxic mycotoxin, fumonisin B1, has been investigated by studying the mechanisms involved during cancer initiation and promotion in rat liver. Cancer initiation is effected through a toxic-proliferative response while t

Fumonisins: history, world-wide occurrence and impact

Autor: W F, Marasas

Publikováno v: Advances in experimental medicine and biology. 392

The history, toxicological effects, world-wide natural occurrence and impact of the fumonisins, food-borne carcinogenic mycotoxins produced by Fusarium moniliforme, are reviewed from the original description of the fungus in 1881 to the present. Foll

Publikováno v: Atherosclerosis. 94(1)

Adding less than 0.5% w/w of culture material of strain MRC 826 of the fungus Fusarium moniliforme to a carbohydrate diet low in fat resulted in an atherogenic plasma lipid profile in a non-human primate. Simultaneously increased plasma fibrinogen an

Publikováno v: The Onderstepoort journal of veterinary research. 57(4)

Leukoencephalomalacia (LEM) was induced by the oral administration of fumonisin B1 (FB1) to 2 horses: a filly received 59.5 mg/kg of a 50% preparation of FB1, administered in 21 doses of 1.25-4 mg/kg over 33 days; a colt, 44.3 mg/kg of 95% pure FB1 i
