Background: T-2 toxin is a mycotoxin of type A trichothecenes produced by several fungal genera such as Fusarium species. Mycotoxins can affect both cell mediated and humoral immune compartments. Objective: The purpose of this study was to investi-gate the effect of T-2 toxin on cytokine production by mouse peritoneal macrophages and lymph node T cells. Methods: Mouse peritoneal macrophages and...
Both T-2 toxin and HT-2 toxin can be conveniently quantitated in crude extracts by using a combination of thin-layer chromatography and fluorodensitometry. This technique was used to follow the production of these toxins by liquid cultures of Fusarium poae (NRRL 3287). T-2 toxin was produced prior to HT-2 toxin and hexadeuterio-T-2 toxin was converted by the culture to trideuterio-HT-2 toxin.
T-2 toxin is a trichothecene mycotoxin produced when Fusarium fungi infect grains, especially oats and wheat. Ingestion of T-2 toxin contaminated grain can cause diarrhea, hemorrhaging, and feed refusal in livestock. Cereal crops infected with mycotoxin-producing fungi form toxin glycosides, sometimes called masked mycotoxins, which are a potential food safety concern because they are not detec...
background: t-2 toxin is a mycotoxin of type a trichothecenes produced by several fungal genera such as fusarium species. mycotoxins can affect both cell mediated and humoral immune compartments. objective: the purpose of this study was to investi-gate the effect of t-2 toxin on cytokine production by mouse peritoneal macrophages and lymph node t cells. methods: mouse peritoneal macrophages and...
The metabolic pathway of T-2 toxin in Curtobacterium sp. strain 114, one of the T-2 toxin-assimilating soil bacteria, was investigated by thin-layer and gas-liquid chromatographic analyses. T-2 toxin added to the basal medium as a single carbon and energy source was biotransformed into HT-2 toxin and an unknown metabolite. Infrared, mass spectrum, proton magnetic resonance, and other physico-ch...
