Age at death from natural scrapie in a flock of Suffolk sheep
Authors:J D Foster  A G Dickinson
Institution:Agricultural and Food Research Council, Edinburgh.
Abstract:This study deals with natural scrapie in a flock of Suffolk sheep being bred to maximise the incidence of the disease and shows that with succeeding generations the incubation period of the disease became progressively shorter until the flock died out. The most likely explanation for this phenomenon is considered to be an increase in the load of infection.
