title: Interferon gamma and prostaglandin in BSE-infected cattle.
abstract: Suspect field cases of BSE infection (displaying clinical signs) were examined for possible alterations of cytokine/autacoid plasma levels and were compared to control cases (not displaying clinical signs of BSE infection). Interferon gamma (IFN-gamma) plasma levels were demonstrated as being elevated in all suspected field cases of BSE infection (irrespective of BSE status; determined via postmortem histopathological examination). We demonstrated that plasma IFN-gamma levels were significantly (P<0.005) higher in suspect cases of BSE infection than in control cases. BSE-positive prostaglandin-E(2), (PGE(2)) plasma levels were demonstrated as being elevated 1.25-fold above BSE-negative cases and 2.22-fold above control cases. No significant (P>0.5) increase in PGE(2)plasma levels was recorded between BSE-positive and -negative. IFN-gamma and PGE(2)plasma levels were examined using commercially available ELISA assay. The results presented in this publication are the first demonstration of alteration in immune state in animals with BSE.
