Chronic Wasting Disease (CWD) and Transmissible Spongiform Encephalopathies (TSE) have brain tissue vacoulation, Scrapie Associated Fibrils, prion protein resistance to proteinase-K digestion, and Western Blot and immunostaining of diseased tissue. Neurotropic, sterol ingesting bacteria of the Class Mollicutes, Mycoplasma or Spiroplasma produce the p-K resistant proteins of the 25 to 30 kDa, fibrils of 4 to 6 nm, and nervous system neuron vacoulation and infectivity of TSE disease
