Effect of Feeding Deoxynivalenol (Vomitoxin)-Contaminated Barley to Horses
Journal of Veterinary Diagnostic Investigation, 199712,13-epoxytrichothec-9-en-8-one) is a naturally occurring trichothecene toxin produced by several Fusarium fungi that parasitize numerous cereal grains. Numerous species of Fusarium have been found to produce DON. The genus Fusarium occurs throughout the world and may affect corn, wheat, barley, oats, rice, and sorghum and complete feed formulations ...

A Short-Term Feeding Study with Deoxynivalenol (Vomitoxin) Using Rats
Toxicological Sciences, 1986Groups of 25 male and 25 female Sprague-Dawley rats were fed diets containing 0, 0.25, 0.5, or 1.0 mg of deoxynivalenol (DON)/kg body wt for approximately 9 weeks. Each animal's body weight and feed consumption were measured weekly. Upon termination of the study, each animal's body, heart, liver, spleen, thymus, and kidneys were weighted.

Vomitoxin (4-deoxynivalenol): effects on reproduction of mice and rats
Toxicology and Applied Pharmacology, 1984Weanling male and female mice (F0) were fed daily diets containing 4-deoxynivalenol (DON) at concentrations that resulted in a dose of 0 or 2.0 mg/kg body wt in Experiment I and 0, 0.375, 0.75, or 1.5 mg/kg body wt in Experiment II. The test diets were continuously fed to the F0 parents and their progeny for the entire duration of these two experiments,

Vomitoxin in diets for rainbow trout (Salmo gairdneri)
Aquaculture, 1983Abstract The present study was conducted to obtain information as to the response and sensitivity of rainbow trout ( Salmo gairdneri ) to diets containing vomitoxin-contaminated corn. Feed refusal occurred when diets contained 20 μ g/g vomitoxin or more, but the trout recovered rapidly when subsequently fed a diet containing no detectable toxin ...

Effect of deoxynivalenol (vomitoxin) on the humoral IM-munity of mice
Toxicology Letters, 1984The effects of vomitoxin (deoxynivalenol; DON) on the immune system were studied in groups of weanling male Swiss Webster mice administered by gavage 0.75, 2.5, and 7.5 mg of vomitoxin per kg body weight. Untreated controls and solvent controls (propylene glycol, ethanol, and distilled water in a ratio of 4:1:5) were also included in this study.

Natural occurrence of vomitoxin in Austrian and Canadian corn
European Journal of Applied Microbiology and Biotechnology, 1979The trichothecene, vomitoxin, was found in two Austrian corn samples at levels of 1.3 and 7.9 ppm and in one Canadian corn sample at a level of 7.9 ppm; all three corn samples were rejected when fed to swine. Feed made from the latter corn sample contained 1.4 ppm vomitoxin. Kernels from these corn samples were examined for Fusarium graminearum.

Occurrence of deoxynivalenol (vomitoxin) in processed cereals and pulses in Turkey
Food Additives and Contaminants, 2003The aim was to investigate the occurrence of deoxynivalenol (DON) in cereal and pulse products in Turkey. DON was detected using high-performance liquid chromatography (HPLC) with ultraviolet detection at 220 nm and positive results greater or equal to 0.60 ppm were confirmed by thin layer chromatography (TLC).

Chemical deoxygenation of the epoxide moiety in deoxynivalenol (vomitoxin)
Canadian Journal of Chemistry, 1985Reaction of triacetoxydeoxynivalenol (3) with hydrobromic acid–acetic acid at reflux temperatures yielded 3α,7α, 13,15-tetraacetoxy-2-bromo apotrichothec-9-en-8-one (5) and 3α,7α,15-triacetoxy-13-bromo-12-hydroxytrichothec-9-en-8-one (4). Dehalohydrination of the 13,12-bromohydrin derivative with Zn–acetic acid followed by deacetylation with sodium ...

Teratological study of Fischer rats fed diet containing added vomitoxin
Food and Chemical Toxicology, 1984Vomitoxin (deoxynivalenol), a tricothecene mycotoxin produced by Fusarium species, has been detected in corn, wheat and other cereal grains intended for consumption by man and by animals used for food. The teratogenic potential of vomitoxin administered in the diet was studied by feeding a vomitoxin-containing certified rat feed ad lib.
