Clinical biochemistry of sporidesmin natural intoxication (facial eczema) of sheep.
The effects of facial eczema, i.e. intoxication by the mycotoxin sporidesmin, were investigated by extensive biochemical screening of serum in 100 controls (A), 31 clinically ill (B) and 219 apparently healthy (C) Manech ewes under field conditions. Dramatic increases of gamma-glutamyltransferase1), alkaline phosphatases, bilirubin, cholesterol, aspartate and alanine aminotransferases, and lactate dehydrogenase confirmed the severity of liver damage in group B, but they were also observed in slightly more than 50% of group C animals. This demonstrated the true extent of the disease, which could be best assessed by the measurement of serum gamma-glutamyltransferase; but since this enzyme was still elevated one year later, it cannot be used as a reliable prognostic parameter.
