abstract = {Prions are proteinaceous pathogens responsible for a
variety of devastating diseases in mammals, including
scrapie in sheep and goats, chronic wasting disease in
cervids, and Creutzfeldt-Jakob disease (CJD) in humans. They
are characterized by their exceptional persistence to common
inactivation procedures. This applies to all possible
sources of prion contamination as prions may be present in
the tissues and biological fluids of infected individuals.
Hence, efficient prion inactivation procedures are still
being sought to minimize the risk of intra- or inter-species
transmission. In the past, photocatalytic treatment has been
proven to be capable of efficiently oxidizing and
inactivating prions. In the present study, the efficacy of
homogeneous photo-Fenton-based photocatalysis as well as
heterogeneous photocatalysis with TiO2 in reducing RML mouse
scrapie infectivity was evaluated. Prion inactivation was
assessed by means of a bioassay, and the results were
confirmed by in vitro experiments. While the prion
infectivity of the RML mouse scrapie was reduced after
treatment with the photo-Fenton reagent, the heterogeneous
photocatalytic treatment of the same prion strain completely
eliminated prion infectivity.},
