Soil Characteristics May Be Related to Chronic Wasting Disease Persistence, Study Finds
Chronic wasting disease (CWD) is a fatal neurological disease that affects deer, elk, and moose. It is caused by an abnormal protein called a prion that damages the brain and nervous system. CWD has been spreading rapidly in North America and has become a major concern for wildlife managers and hunters. A new study suggests that soil characteristics may be related to CWD persistence.
What is Chronic Wasting Disease?
Chronic wasting disease (CWD) is a transmissible spongiform encephalopathy (TSE) that affects cervids, including deer, elk, and moose. It was first identified in captive mule deer in Colorado in the late 1960s and has since spread to wild populations in 26 states and three Canadian provinces. CWD is caused by an abnormal protein called a prion that damages the brain and nervous system. There is no known cure or vaccine for CWD, and infected animals usually die within two years of infection.
The Study
A new study published in the journal PLOS ONE suggests that soil characteristics may be related to CWD persistence. The study was conducted by researchers from the University of Illinois at Urbana-Champaign, the Illinois Natural History Survey, and the Wisconsin Department of Natural Resources.
The researchers collected soil samples from 11 CWD-positive sites and 11 CWD-negative sites in Wisconsin. They analyzed the samples for various physical and chemical properties, including pH, organic matter content, nutrient levels, and microbial communities.
The results showed that soil characteristics differed significantly between CWD-positive and CWD-negative sites. Specifically, CWD-positive sites had higher levels of clay, iron, manganese, and aluminum than CWD-negative sites. They also had lower pH values and higher levels of organic matter.
Implications
The study's findings suggest that soil characteristics may play a role in CWD persistence. The researchers speculate that the prions responsible for CWD may bind more strongly to certain soil components, making them more resistant to degradation. They also suggest that soil pH and nutrient levels may affect the survival and replication of prions in the environment.
The implications of these findings are significant for wildlife managers and hunters. If soil characteristics are indeed related to CWD persistence, it may be possible to develop management strategies that target high-risk areas. For example, wildlife managers could focus their efforts on reducing deer densities in areas with high levels of clay, iron, manganese, and aluminum. Hunters could also avoid harvesting deer in these areas.
Conclusion
Chronic wasting disease is a serious threat to North America's deer, elk, and moose populations. A new study suggests that soil characteristics may be related to CWD persistence. The study's findings have important implications for wildlife managers and hunters, who may be able to use this information to develop more effective management strategies.
