Area of Science:

  • Veterinary Medicine
  • Neuroscience
  • Infectious Diseases

Background:

  • Prions are infectious agents lacking a genome, causing pathologies primarily through prion protein (PrPSc) conformation.
  • Prion diseases affect humans and animals, including food-producing ruminants like cattle, sheep, goats, and deer.
  • Bovine spongiform encephalopathy (BSE) is zoonotic, linked to variant Creutzfeldt Jakob disease (vCJD) in humans.

Purpose of the Study:

  • To review current and emerging prion typing methodologies.
  • To focus on identifying prion types in food-producing animals.
  • To aid in the development of diagnostic tests for novel prion diseases.

Main Methods:

  • Review of existing literature on prion typing techniques.
  • Analysis of diagnostic test capabilities for differentiating prion strains.
  • Examination of emerging prion types in food-producing animals and cervids.

Main Results:

  • Current diagnostic tests differentiate BSE from non-zoonotic agents.
  • Atypical forms of scrapie and BSE, along with two types of chronic wasting disease (CWD) in cervids, have been reported.
  • Prion typing is essential for distinguishing between different prion diseases.

Conclusions:

  • Prion typing remains a critical aspect of animal prion diagnosis.
  • Focus is shifting towards identifying the spectrum of prion types in food-producing animals.
  • Developing tests for emerging prion diseases is a key future direction.
