Which diseases are considered disease problems in cervids in the United States?

The correct answer identifies Brucellosis, Tuberculosis, and Chronic Wasting Disease as significant disease problems in cervids in the United States. Brucellosis is a bacterial infection that can affect various species, including elk and deer, and it has serious implications for wildlife management and livestock health. Tuberculosis, specifically bovine tuberculosis, is a concern in wildlife, impacting deer populations and potentially transmitting to livestock. Chronic Wasting Disease (CWD) is a neurodegenerative disease that affects deer and elk, leading to declining populations and raised concerns about transmission to other wildlife and livestock.

These diseases are particularly concerning because they can spread rapidly within cervid populations and have the potential to impact agricultural interests, wildlife conservation, and public health. In contrast, the other choices contain diseases that are either not typically associated with cervids or are not recognized as significant disease problems in this context. For instance, Mad Cow Disease primarily affects cattle and is not relevant to cervids, while Foot-and-Mouth Disease is a highly contagious viral disease affecting cloven-hoofed animals but not specifically targeting cervids in the same manner as the three listed in the correct answer.
