Incidence of Trichothecenes Deoxynivalenol and T-2 Toxin in Poultry Feed Mixtures

نویسندگان

چکیده

Abstract Trichothecenes are among the most important fusariotoxins. According to their chemical structure, they divided into 4 groups (A – D). In terms of agriculture, trichothecenes A and B greatest importance. this study, incidence (deoxynivalenol T-2 toxin) in mixed feed for broilers turkeys were determined. Deoxynivalenol was detected all analysed samples mixture (100 %) at an average concentration 1.776 ppm; 0.675 ppm, respectively. toxin present 93.8 % 36.625 ppb tested turkey (average level 25.899 ppb). The deoxynivalenol poultry did not exceed concentrations recommended by legislation.

T-2 toxin: incidence and toxicity in poultry.

T-2 toxin is the most toxic type A trichothecene mycotoxin. It is the secondary metabolite of the Fusarium fungi, and is common in grain and animal feed. Toxic effects have been shown both in experimental animals and in livestock. It has been implicated in several outbreaks of human mycotoxicoses. Toxic effects in poultry include inhibition of protein, DNA, and RNA synthesis, cytotoxicity, immu...

Toxicological features of T-2 toxin and related trichothecenes.

Toxicological characteristics of T-2 toxin and related trichothecenes, mycotoxins produced by Fusarium, Trichoderma, Verrucaria, and others, were investigated in regard to LD50 values, dermal toxicity, hematological changes, and tumorigenicity. The LD50 values (mg/kg) of T-2 toxin in adult male mice were po 10.5, ip 5.2, sc 2.1, and iv 4.2, and those of nivalenol were ip 4.1 and iv 6.3. These d...

Comparative induction of 28S ribosomal RNA cleavage by ricin and the trichothecenes deoxynivalenol and T-2 toxin in the macrophage.

Ribosome-inactivating proteins (RIPs) and sesquiterpenoid trichothecene mycotoxins are known to bind to eukaryotic ribosomes, inhibit translation and activate mitogen-activated protein kinases. Here we compared the capacities of the RIP ricin to promote 28S ribosomal RNA (rRNA) cleavage with that of the trichothecenes, deoxynivalenol (DON), and T-2 toxin (T-2). In a cell-free model, exposure to...

Incidence of fumonisins, moniliformin and Fusarium species in poultry feed mixtures from Slovakia.

A total of 50 samples of poultry feed mixtures of Slovak origin were analysed for fumonisin B(1) and B(2) (FB(1), FB(2)) and moniliformin (MON) using SAX-clean up procedure being detected by high pressure liquid chromatography with mass spectrometry (HPLC-MS) and diode array detection (HPLC-DAD), respectively. The samples were also simultaneously investigated for Fusarium species occurrence, an...

The Impact of the Fusarium Toxin Deoxynivalenol (DON) on Poultry

Deoxynivalenol (DON), a trichothecene, is prevalent worldwide in crops used for food and feed production. The presence of mycotoxins in poultry feeds is a significant factor for financial losses to animal industries. Although DON is one of the least acutely toxic trichothecenes, it should be treated as an important food safety issue because it is a common contaminant of grains. Special care mus...
