Understanding the Spread of Chronic Wasting Disease
The exact manner in which chronic wasting disease spreads remains a mystery. However, it is believed that this infectious disease can be transmitted through various bodily fluids such as urine, feces, or saliva. The primary mode of transmission is lateral, indicating that it spreads from one animal to another. While there is a possibility of maternal transmission, it is considered to have minimal impact on the overall maintenance of epidemics.
Methods for Detecting Chronic Wasting Disease
When it comes to detecting chronic wasting disease (CWD), there is currently only one definitive method. This involves conducting an examination of the tonsils, brain, or lymph nodes, but unfortunately, it can only be done after the individual has passed away. During this examination, a thorough analysis of the brain is conducted to identify the presence of the characteristic microscopic spongiform lesions.
In addition to examining the brain, medical professionals also check for the accumulation of the prion protein in the brain and lymphoid tissues. To do this, they employ a technique called immunohistochemistry. This technique helps in detecting the abnormal accumulation of the prion protein, which is a key indicator of chronic wasting disease.
