* Diseases and Parasites

Research on desert mule deer indicates that diseases and parasites are of little management concern at the present time. Evidence of exposure to bluetongue and epizootic hemorhagic disease (EHD) have been documented in mule deer. The most common disease agent among mule deer appears to be warts. Mule deer from the Trans-Pecos and Panhandle regions have not shown any incidence of brucellosis, leptospirosis or infectious bovine rhinotracheitis (IBR). Most deer commonly harbor light infestations of ticks and nasal blots, but not at levels high enough to present a health problem to the deer. Likewise, internal parasites, especially stomach worms, are common but are not at sufficient levels to cause clinical symptoms. However, the concentration of individuals at feeding sites increases the potential for disease transmission. Because disease causing organisms can be transmitted through the soil, supplemental feed should not be placed on the ground. Some type of trough should be used and, ideally, the feeding site should be relocated every year or two.
