The Impact of Storage Temperature and Time on Ergot Alkaloid Concentrations
Toxins, 2023 Ergot sclerotia produce toxic secondary metabolites, ergot alkaloids, that infect cereal crops and grasses. Ergot alkaloids have two isomeric configurations: the C-8-R-isomer (R-epimer), and the C-8-S-isomer (S-epimer).

Fate of Ergot Alkaloids during Laboratory Scale Durum Processing and Pasta Production
Toxins, 2019 The fate of ergot alkaloids during the milling of durum and subsequent production and cooking of pasta was examined. Durum samples containing varying amounts of ergot sclerotia (0.01–0.1% by mass) were milled, and all milling product was analyzed ...

Differentially expressed genes in cotyledon of ewes fed mycotoxins
BMC Genomics, 2020 Background Ergot alkaloids (E+) are mycotoxins produced by the endophytic fungus, Epichloë coenophiala, in tall fescue that are associated with ergotism in animals.

Ergot alkaloids contribute to virulence in an insect model of invasive aspergillosis
Scientific Reports, 2017 Neosartorya fumigata (Aspergillus fumigatus) is the most common cause of invasive aspergillosis, a frequently fatal lung disease primarily affecting immunocompromised individuals. This opportunistic fungal pathogen produces several classes of specialised

Influence of Prolonged Serotonin and Ergovaline Pre-Exposure on Vasoconstriction Ex Vivo
Toxins, 2021 Ergot alkaloid mycotoxins interfere in many functions associated with serotonergic neurotransmitters. Therefore, the objective was to evaluate whether the association of serotonin (5-hydroxytryptamine, 5-HT) and ergot alkaloids during a 24 h pre ...
