An important aspect of the bovine spongiform encephalopathy (BSE) epidemic has been an apparent age-dependent risk of infection, with younger cattle being more likely to become infected than older cattle. Our objective was to determine the age-depend

The frequencies of prion protein (PrP) genotypes were investigated in 15 scrapie-affected flocks in Great Britain. The flocks were heterogeneous in the frequencies of different genotypes and alleles, and in their age distributions. The median flock f

SUMMARYSurveillance activities for ovine scrapie have expanded in the 21st century, following concerns about the potential for a hidden epidemic of bovine spongiform encephalopathy in European sheep populations. Large-scale surveys have been used to
