Cover for The diagnostic significance of detecting <i xmlns="http://www.w3.org/1999/xhtml">Rathayibacter toxicus</i> in the rumen contents and feces of sheep that may be affected by annual ryegrass toxicity.

This study was conducted to diagnose acute, subacute and chronic annual ryegrass (Lolium multiflorum) toxicity (ARGT) in sheep by detection of corynetoxins (CT) produced by Rathayibacter toxicus in the seed heads in the rumen fluid and faeces using a modified ELISA. It was shown that although the...

Cover for Metabolism of the endophyte toxin lolitrem B in cattle liver microsomes.

In this study, cattle liver microsomes were cultured with 2.9 µM lolitrem B from the endophyte Neotyphodium lolii infecting perennial ryegrass (Lolium perenne). Metabolites were detected using HPLC and mass spectrometry. It was shown that lolitrem B was metabolized by bovine liver microsomes at an...
