[Cellular nucleic acids in serum and plasma as new diagnostic tools]

Area of Science:

• Veterinary Medicine
• Neurodegenerative Diseases
• Prion Biology

Context:

• Current bovine spongiform encephalopathy (BSE) diagnosis relies on post-mortem examination of brain stem tissue.
• Protease-resistant prions are typically identified in the obex region of deceased animals.
• There is a critical need for in vivo diagnostic methods in veterinary medicine and agriculture.

Purpose:

• To investigate novel biomarkers for early in vivo detection of infectious diseases, specifically focusing on bovine spongiform encephalopathy.
• To explore the potential of circulating cellular nucleic acids in plasma or serum as surrogate markers.
• To move beyond traditional methods limited to post-mortem analysis of the central nervous system.

Summary:

• Bovine spongiform encephalopathy (BSE) diagnosis is currently restricted to post-mortem analysis of brain tissue.
• Developing an in vivo detection assay is paramount for veterinary and agricultural applications.
• This research proposes circulating cellular nucleic acids in blood as a new approach for detecting infectious diseases, offering a potential alternative to late-stage central nervous system markers.

Impact:

• Facilitates the development of early diagnostic tools for BSE in live animals.
• Enhances animal health surveillance and food safety measures.
• Opens new avenues for infectious disease diagnostics using circulating nucleic acids.
