Abstract

Disinfectants containing 3-methyl-4-chlorophenol were tested for their capacity to inactivate the infectious agent of scrapie. Coincubation of brain homogenates prepared from terminally ill scrapie-infected hamsters with the disinfectants rendered the prion protein PrPSc sensitive to proteinase K digestion. Inoculation of hamsters with disinfectant-treated samples indicated a reduction in infectivity levels to below the limit of detection.
