چکیده انگلیسی
Since scrapie and bovine spongiform encephalopathy (BSE) in sheep are clinicopathologically indistinguishable, BSE in sheep may have been misdiagnosed as scrapie. Disease-specific prion protein (PrPd) patterns in archival tissues of 38 Irish ARQ/ARQ sheep diagnosed as scrapie-affected were compared to those in four Dutch BSE-challenged sheep. When medulla oblongata was immunolabelled with an antibody directed against amino acids 93-99 of ovine prion protein (ovPrP), intraneuronal PrPd was apparent in all 38 Irish sheep but was absent in BSE-challenged sheep. When lymphoid follicles were immunolabelled with antibodies directed against amino acids 93-106 of ovPrP, granule clusters of PrPd were seen in 34 of the 38 Irish sheep. Follicles of the remaining four archive sheep contained either no PrPd or single PrPd granules, similar to follicles from BSE-challenged sheep. Based on the medulla results, none of the archival cases had BSE-derived disease. The identification of some scrapie sheep with little or no intrafollicular PrPd suggests that this technique may be limited in discriminating between the two diseases.
