Sterigmatocystin in dairy cattle feed contaminated with Aspergillus versicolor.
نویسندگان
چکیده
Sterigmatocystin (7.75 micrograms/g of feed) and a high-propagule-density of Aspergillus versicolor were detected in feed associated with acute clinical symptoms of bloody diarrhea and death in dairy cattle. Nine isolates of A. versicolor from the feed produced 13 to 89 micrograms of sterigmatocystin per g on cracked corn and lower amounts in liquid culture. This is the first report of sterigmatocystin in dairy cattle feed in the United States.

Anthraquinones in the biosynthesis of sterigmatocystin by Aspergillus versicolor.
14C-labeled averufin, versiconal hemiacetal acetate, and versicolorin A were efficiently converted to sterigmatocystin by Aspergillus versicolor, thus providing experimental evidence that these anthraquinones are biosynthetic precursors of sterigmatocystin, a xanthone.

Background/objective: Aflatoxin M1 (AFM1) is a metabolite of the aflatoxin B1 found in the liver of livestock, as a result of feeding livestock with contaminated food. Certain species of Aspergillus are responsible for producing aflatoxin. The present study was performed to evaluate the measurement of AFM1, by ELISA method, in milk samples collected from dairy farms of Shahre Ghods, Shahriar (T...

The objective of this study was to evaluate the metabolic profile of cattle fed with or without zearalenone (ZEN) and sterigmatocystin (STC)-contaminated diets using a gas chromatography-mass spectrometry metabolomics approach. Urinary samples were collected from individual animals (n = 6 per herd) from fattening female Japanese Black (JB) cattle herds (23 months old, 550-600 kg). Herd 1 had pe...
