Current understanding of PrnP Genetics: A tool for Molecular Assisted Selection in Sheep Populations (A review)

Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca. Animal Science and Biotechnologies, 2016
Scrapie is a neurodegenerative prion disease of sheep, goats and mouflons, belonging to the group of transmissible spongiform encephalopathies (TSEs), which affects humans as well. Even though classical scrapie has been known for over 250 years, the 1985

Evaluation of alternative methods of tunnel composting (submitted by the European Composting Network) II

EFSA Journal, Volume 22, Issue 4, April 2024.
Abstract Two alternative methods for producing compost in a tunnel, from certain category (Cat.) 3 animal by‐products (ABP) and other non‐ABP material, were assessed. The first method proposed a minimum temperature of 55°C for 72 h and the second 60°C for 48 h, both with a maximum particle size of 200 mm.

Change in the molecular properties of CH1641 prions after transmission to wild‐type mice: Evidence for a single strain

Neuropathology and Applied Neurobiology, Volume 50, Issue 1, February 2024.
The scrapie isolate CH1641 was transmitted to various mouse lines and PrPSc depositions at the level of the thalamus were immunostained. CH1641 passaged through Tg338 (A), Tg110 (B), RIII (C) and VM (D) mice was cross passaged to Tg59 mice. All PrPSc profiles at the level of the thalamus were similar to the PrPSc profile of the homologous passage of ...

Experimental transmission of atypical scrapie to sheep

BMC Veterinary Research, 2007
Background Active surveillance for transmissible spongiform encephalopathies in small ruminants has been an EU regulatory requirement since 2002. A number of European countries have subsequently reported cases of atypical scrapie, similar to previously ...

No H- and L-type cases in Belgium in cattle diagnosed with bovine spongiform encephalopathy (1999-2008) aging seven years and older [PDF]

, 2010
Background The bovine spongiform encephalopathy (BSE) epidemic presented homogeneity of the phenotype. This classical BSE (called C-type) was probably due to the contamination of the food chain by a single prion strain.

Scientific Opinion on BSE/TSE infectivity in small ruminant tissues

EFSA Journal, 2010
The objectives addressed were i) to provide an update on TSE (Transmissible Spongiform Encephalopathy) infectivity distribution in small ruminant tissues; and ii) to indicate based on the current epidemiological situation as regards to BSE (Bovine ...

Interspecies transmission to bovinized transgenic mice uncovers new features of a CH1641-like scrapie isolate

Veterinary Research, 2018
In animal prion diseases, including bovine spongiform encephalopathy (BSE) in cattle, chronic wasting disease in cervids, and scrapie in sheep and goats, a disease-associated isoform of prion protein (PrPd) accumulates in the brains of affected animals ...

Prion protein self-peptides modulate prion interactions and conversion [PDF]

, 2009
Background: Molecular mechanisms underlying prion agent replication, converting host-encoded cellular prion protein (PrPC) into the scrapie associated isoform (PrPSc), are poorly understood.
