White-tail deer brain sectioning for post-mortem processing. The caudal aspect of the frontal lobe (section 1) and obex (section 8) were analysed by RT-QuIC. Prion positivity has been shown to progress from caudal to rostral across the brain. Progression of CWD was characterized from tonsil, to S1 brain section/olfactory bulb, and to nasal swab secretions collected by cytology brush.
