Genotyping and surveillance for scrapie in Finnish sheep

BMC Veterinary Research, 2012
Background The progression of scrapie is known to be influenced by the amino acid polymorphisms of the host prion protein (PrP) gene. There is no breeding programme for TSE resistance in sheep in Finland, but a scrapie control programme has been in place

Classical BSE prions emerge from asymptomatic pigs challenged with atypical/Nor98 scrapie

Scientific Reports, 2021
Pigs are susceptible to infection with the classical bovine spongiform encephalopathy (C-BSE) agent following experimental inoculation, and PrPSc accumulation was detected in porcine tissues after the inoculation of certain scrapie and chronic wasting ...

Reasoning under uncertainty: the role of two informal fallacies in an emerging scientific inquiry [PDF]

, 2002
It is now commonplace in fallacy inquiry for many of the traditional informal fallacies to be viewed as reasonable or non-fallacious modes of argument.

Scrapie-Associated Tubulofilamentous Particles in Scrapie Hamsters

Intervirology, 1992
Examination of thin sections from the cerebral cortex of scrapie-infected hamster brains revealed characteristic circular 26-30 nm diameter tubulofilamentous particles, identical to those previously described in both experimentally induced scrapie in mice, hamsters and natural scrapie of sheep, bovine spongiform encephalopathy and human Creutzfeldt ...

Possible alignment of the EU BSE surveillance with the new WOAH provisions

EFSA Journal, Volume 24, Issue 4, April 2026.
Abstract The European Commission requested the assessment of the capacity of the surveillance provisions of the World Organization for Animal Health (WOAH) to detect bovine spongiform encephalopathy (BSE) cases (C‐, H‐ and L‐type) in the European Union (EU) and to propose if any current EU surveillance provisions should be kept.

Optimising the Use of Cryopreserved Genetic Resources for the Selection and Conservation of Animal Populations

Journal of Animal Breeding and Genetics, Volume 143, Issue 1, Page 50-67, January 2026.
ABSTRACT Genetic diversity is essential for the sustainability and adaptability of populations, and is thus a central pillar of the agro‐ecological transition. However, within a population, it is inevitable that some amount of genetic variability is lost, and efforts must be made to limit this as much as possible.

Synthesis and structural characterization of a mimetic membrane-anchored prion protein [PDF]

, 2006
During pathogenesis of transmissible spongiform encephalopathies (TSEs) an abnormal form (PrPSc) of the host encoded prion protein (PrPC) accumulates in insoluble fibrils and plaques. The two forms of PrP appear to have identical covalent structures, but

Epigenetic Modifications Influence Reproductive Traits in Small Ruminants

Veterinary Medicine International, Volume 2026, Issue 1, 2026.
The epigenome undergoes dynamic changes shaped by the intricate interplay of genetic and environmental factors, which are crucial for individual growth and development. Recent studies suggest that factors such as nutrition, thermal stress (TS), infections, and assisted reproductive technologies (ARTs) can influence epigenetic changes in small ruminants

Incidence of infection in Prnp ARR/ARR sheep following experimental inoculation with or natural exposure to classical scrapie. [PDF]

PLoS ONE, 2014
The prion protein gene (Prnp) is highly influential in determining risk and susceptibility of sheep exposed to classical scrapie. Sheep homozygous for alanine at codon 136 and arginine at codons 154 and 171 (ARR/ARR) of the Prnp gene are historically ...
