New process for T-2 toxin production.
Strains of Fusarium produced high levels of T-2 toxin when cultured on certain media absorbed into vermiculite. Modified Gregory medium was nutritionally complex (2% soya meal, 0.5% corn steep liquor, 10% glucose) and, when inoculated with the appropriate fungal strain, yielded maximum T-2 toxin within 24 days of incubation at 19 degrees C. On Vogel synthetic medium N (H. J. Vogel, Microb. Gen...
متن کاملProduction of antibody against T-2 toxin.
Antibody against T-2 toxin was obtained after immunization of rabbits with bovine serum albumin-T-2 hemisuccinate conjugate. The antibody had greatest binding efficiency for T-2 toxin, less efficiency for HT-2, and least for T-2 triol. Cross-reaction of antibody with neosolaniol, T-2 tetraol, and 8-acetyl-neosolaniol was very weak. Diacetoxyscirpenol, trichodermin, vomitoxin, and verrucarin A e...
متن کاملT-2 toxin production by Fusarium tricinctum on solid substrate.
A method has been developed to produce and purify gram quantities of T-2 toxin [4beta, 15-diacetoxy-8alpha-(3-methylbutyryloxy)-12, 13-epoxytrichothec-9-en-3alpha-ol], a mycotoxin elaborated by a strain of Fusarium tricinctum isolated from toxic corn. After growing for 3 weeks at 15 C on 1,200 g of white corn grits, F. tricinctum NRRL 3299 elaborated at least 9.0 g of T-2 toxin, and 2.3 g of cr...
متن کاملEffects of T-2 Toxin on Cytokine Produc-tion by Mice Peritoneal Macrophages and Lymph Node T-Cells
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...
متن کاملIn vitro metabolism of T-2 toxin.
Incubation of T-2 toxin with the 9,000 x g supernatant fluid of both human and bovine liver homogenate resulted in conversion to a single, deacetylated product identified as HT-2 toxin. Metabolism is more rapid in human liver. HT-2 toxin was not produced when human plasma was the incubating medium nor was it produced by treatment of T-2 toxin with simulated gastric juice. T-2 toxin was stable i...
