Cellular distribution of the prion protein in palatine tonsils of mule deer (Odocoileus hemionus) and Rocky Mountain elk (Cervus elaphus nelsoni)

MM Hille, JE Jewell, EL Belden - Journal of Veterinary Medical Science, 2019

... While CWD [chronic wasting disease] is a neurodegenerative disease, lymphoid accumulation of the abnormal isoform of the prion protein (PrPSc) is detectable early in the course of infection. It has been shown that a large portion of the PrPSc lymphoid accumulation in infected mule deer takes place on the surface of follicular dendritic cells (FDCs). In mice, FDC expression of PrPC has been shown to be essential for PrPSc accumulation...

Impacts of chronic wasting disease on a low density mule deer (Odocoileus hemionus) population in the San Andres Mountains, Chihuahuan Desert, New Mexico LC Bender, CL Rodden, P Mathis, ME Weisenberger… - ACTA ZOOLÓGICA …, 2019

... . Distribution of infected deer was strongly related to presence of other infected deer. Annual survival rates of mule deer and population rate-of-increase suggested little effect of CWD on population-level mortality given observed prevalence. Transmission and reservoirs of CWD in the SAM were likely limited by low deer densities, patchy distribution, and environmental characteristics (i.e., low clay content of soils) unfavorable to prion persistence, characteristics that are typical of most mule deer populations in the Chihuahuan Desert ecoregion...

These findings suggest that these cases in moose represent a novel type of CWD...


Chronic wasting disease detection and mortality sources in semi-protected deer population

KL Schuler, JA Jenks, RW Klaver, CS Jennelle… - Wildlife Biology, 2018

... data best supported a model with time-invariant encounter probability and an annual survival of 72.8%. Even without direct pressure from hunting within the park, average life expectancy in this population was 3.2 years. Only 68% of mortalities contained sufficient material for CWD sampling (because of predation and scavenger activity) and >42% of these were CWD-positive. These findings underscore the possible biases in postmortem  surveillance estimates of disease prevalence because of potential for subclinical infected animals to be removed by predators and not tested.
