Trichothecene mycotoxins from Fusarium culmorum cultures.
Chemical analysis of the culture filtrates of Fusarium culmorum CMI 14764 has demonstrated the presence of seven trichothecene mycotoxins. Major metabolites are 3-acetyldeoxynivalenol and 7 alpha, 8 alpha-dihydroxycalonectrin, with 3,15-diacetyldeoxynivalenol, deoxynivalenol, calonectrin, isotrichodermin and 12,13-epoxytrichothec-9-ene (EPT) as minor products. The occurrence of the rarely encou...
متن کاملInhibitionby Trichothecene Mycotoxins of Replication of Herpes Simplex Virus Type
The efiects of the trichothecene mycotoxins diacetoxyscirpenol, neosoluniol and T-2 toxin on the rep}ication of herpes simplex virus type 2 (HSV-2) in HEp-2 cells werc examined. The 50% inhibitory concentrations for HSV-2 replication were 2,3 ng,iml for diacetoxyscirpenol, 52,Ong/ml for neosolaniol, and 1.6ngl'ml for T-2 toxin, The addition of these toxins to the cells within 4hr atter HSV-2 in...
متن کاملFate of trichothecene mycotoxins during the processing: milling and baking.
Toxic secondary metabolites produced by fungi representing Fusarium genus are common contaminants in cereals worldwide. To estimate the dietary intake of these trichothecene mycotoxins, information on their fate during cereal processing is needed. Up-to-date techniques such as high-performance liquid chromatography (HPLC) coupled with tandem mass spectrometry (LC-MS/MS) was used for the analysi...
متن کاملDetection of polar and macrocyclic trichothecene mycotoxins from indoor environments.
A method is described for the qualitative and semi-quantitative simultaneous determination of both non-macrocyclic and macrocyclic trichothecene biotoxins from samples derived from indoor environments. The method includes extraction, sample pre-treatment and reversed-phase HPLC separation followed by tandem mass spectrometric identification and quantification using electrospray ionization on a ...
متن کاملMicrobial detoxification of eleven food and feed contaminating trichothecene mycotoxins
BACKGROUND Contamination of agricultural commodities with multiple trichothecene mycotoxins, produced by toxigenic Fusarium species, is a food safety issue, which greatly affects grain production and marketing worldwide. Importantly, exposure to multiple trichothecenes may increase toxicity in animals due to their synergistic and/or additive effects. To address the problem this study aimed to a...
