A gene cluster for ergovaline biosynthesis

NZGA: Research and Practice Series, 2007
Some strains of Epichloë and Neotyphodium endophytes produce the ergot alkaloid ergovaline, which is implicated in livestock toxicoses caused by ingestion of endophyte-infected grasses.

ERGOVALINE MOVEMENT ACROSS CACO-2 CELLS

In Vitro Cellular and Developmental Biology--Animal, 2005
Ergovaline's role in the direct causation of fescue toxicosis first requires establishment of its dietary absorption. Therefore, ergovaline movement across human intestinal cells was assessed using Caco-2 cells derived from human colon carcinoma. A pre-equilibrated mixture of ergovaline/ergovalinine (60:40 ratio of isomers) was added to the apical ...

Microbiomic Comparison of the Intestine of the Earthworm Eisenia fetida Fed Ergovaline

Current Microbiology, 2009
Tall fescue toxicosis and ergot alkaloids cost U.S. livestock producers approximately one billion dollars in annual livestock production loss annually. Ergovaline (EV) is the tall fescue alkaloid primarily responsible for clinical disease in livestock.

Ergovaline does not alter the severity of ryegrass staggers induced by lolitrem B

New Zealand Veterinary Journal, 2018
To investigate a possible interaction between lolitrem B and ergovaline by comparing the incidence and severity of ryegrass staggers in sheep grazing ryegrass (Lolium perenne) containing lolitrem B or ryegrass containing both lolitrem B and ergovaline.Ninety lambs, aged approximately 6 months, were grazed on plots of perennial ryegrass infected with ...

Effects of feeding ergovaline on lamb performance in a heat stress environment

Journal of Animal Science, 2003
Lambs exposed to a heat-stressed environment (33 degrees C, 50% relative humidity) were used in three experiments to determine whether ergovaline (EV) is the primary toxin involved in fescue toxicosis. The first study evaluated the effects of feeding diets containing increasing levels of endophyte-infected tall fescue seed (E+) and decreasing levels of
