Toxins, 2022 As the contamination of cereal grains with ergot has been increasing in Western Canada, studies were undertaken to evaluate the impacts of heating (60, 80, 120, or 190 °C) alone or in combination with pelleting on concentrations of ergot alkaloids ...

Impacts of cereal ergot in food animal production
Frontiers in Veterinary Science, 2016 The negative impacts of ergot contamination of grain on the health of humans and animals were first documented during the 5th century AD. Although ergotism is now rare in humans, cleaning contaminated grain concentrates ergot bodies in screenings which ...

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).

Endophyte Infected Tall Fescue: Plant Symbiosis to Animal Toxicosis
Frontiers in Veterinary Science, 2021 Endophyte-infected fescue is a major cool season forage used for livestock production in the United States and through other areas of the world. A unique aspect of this forage resource is the symbiotic relationship with an endophytic fungus (Epichloë ...

Cleaving Ergot Alkaloids by Hydrazinolysis—A Promising Approach for a Sum Parameter Screening Method
Toxins, 2021 Ergot alkaloids are mycotoxins formed by fungi of the Claviceps genus, which are some of the most common contaminants of food and feed worldwide. These toxins are a structurally heterogeneous group of compounds, sharing an ergoline backbone.

Analysis of ergot alkaloid gene expression and ergine levels in different parts of Ipomoea asarifolia [PDF]
PeerJBackground Ergot alkaloids are renowned for their pharmacological significance and were historically attributed to fungal symbioses with cereal crops and grasses.

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.

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 ...
