It would be interesting to see a study done on whether these genetically altered mice can contract CWD by ingesting unaltered deer meat from a CWD infected deer. In the article Atlasman has quoted, the mice have the pathogens injected directly into their brains. That creates a high concentration of the infection and an abnormal way of contracting it. I'd be a lot more worried if any scientist can prove that CWD can be transmitted through much smaller doses that have been ingested. That way, we are comparing apples to apples, not apples to oranges.
