The mule deer is a target for various viral, bacterial, and parasitic diseases such as gastrointestinal nematodes, parasitic meningeal worms, neurologic disease, and foot-and-mouth disease.
The mule deer is a target for various viral, bacterial, and parasitic diseases.
For example, heavy amounts of gastrointestinal nematodes may cause death in mule deer. This parasitic disease is usually indicative of such predisposing factors as high mule deer density and malnutrition.
Infection by the parasitic meningeal worm can cause fatal neurologic disease in mule deer.
Livestock may transmit viral diseases to mule deer as seen in foot-and-mouth disease. This infection is characterized by blisters in the mouth, above the hooves, and between the digits.
