Ergot Alkaloids in Feed for Pekin Ducks: Toxic Effects, Metabolism and Carry Over into Edible Tissues

open access: yesToxins, 2015
Hardened sclerotia (ergots) of Claviceps purpurea contaminate cereal grains and contain toxic ergot alkaloids (EA). Information on EA toxicity in ducks is scarce.

The Usage of Ergot (Claviceps purpurea (fr.) Tul.) in Obstetrics and Gynecology: A Historical Perspective

open access: yesToxins, 2021
In the past centuries consumption of bread made of ergot-infected flour resulted in mass poisonings and miscarriages. The reason was the sclerotia of Claviceps purpurea (Fr.) Tul.—a source of noxious ergot alkaloids (ergotamine and ergovaline).

An integrated targeted and untargeted approach for the analysis of ergot alkaloids in cereals using UHPLC - hybrid quadrupole time-of-flight mass spectrometry [PDF]

open access: yes, 2015
An ultra-high performance liquid chromatography hybrid quadrupole time of flight (Q-TOF) mass spectrometry (MS) method is described for the simultaneous quantitative determination of common ergot alkaloids and the screening, detection and identification ...

Ergochromes: Heretofore Neglected Side of Ergot Toxicity

open access: yesToxins, 2019
Ergot, fungal genus Claviceps, are worldwide distributed grass pathogens known for their production of toxic ergot alkaloids (EAs) and the great agricultural impact they have on both cereal crop and farm animal production.

Effect of Field-applied Fungicides on Claviceps purpurea Sclerotia and Associated Toxins in Wheat

open access: yesJournal of Food Protection, 2023
Claviceps purpurea (Fr.) Tul is the causal organism for ergot impacting grass hosts, including wheat. The pathogen produces ergot alkaloids (EAs) during the development of mature sclerotia leading to potential wheat quality discounts or rejection at the ...

Mycotoxin exposure assessments in a multi-center European validation study by 24-hour dietary recall and biological fluid sampling [PDF]

open access: yes, 2020
The European Food Consumption Validation (EFCOVAL) project includes 600 men and women from Belgium, the Czech Republic, France, the Netherlands, and Norway, who had given serum and 24-hour urine samples, and completed 24-hour dietary recall (24-HDR ...

Vasoactive Effects of Acute Ergot Exposure in Sheep

open access: yesToxins, 2021
Ergotism is a common and increasing problem in Saskatchewan’s livestock. Chronic exposure to low concentrations of ergot alkaloids is known to cause severe arterial vasoconstriction and gangrene through the activation of adrenergic and serotonergic ...

Validation of a New Sensitive Method for the Detection and Quantification of R and S-Epimers of Ergot Alkaloids in Canadian Spring Wheat Utilizing Deuterated Lysergic Acid Diethylamide as an Internal Standard

open access: yesToxins, 2021
Ergot sclerotia effect cereal crops intended for consumption. Ergot alkaloids within ergot sclerotia are assessed to ensure contamination is below safety standards established for human and animal health.

Partial Reconstruction of the Ergot Alkaloid Pathway by Heterologous Gene Expression in Aspergillus nidulans

open access: yesToxins, 2013
Ergot alkaloids are pharmaceutically and agriculturally important secondary metabolites produced by several species of fungi. Ergot alkaloid pathways vary among different fungal lineages, but the pathway intermediate chanoclavine-I is evolutionarily ...

Ergot Alkaloids on Cereals and Seeds: Analytical Methods, Occurrence, and Future Perspectives

open access: yesMolecules, 2023
Ergot alkaloids are secondary metabolites resulting from fungi of the genus Claviceps that have proven to be highly toxic. These mycotoxins commonly infect cereal crops such as wheat, rye, barley, and oats.
