Are Pronghorn Susceptible to Specific Diseases?

Disease Susceptibility

Pronghorn antelope are highly susceptible to brucellosis, a bacterial disease caused by Brucella abortus. Brucellosis can cause reproductive issues such as abortion, stillbirth, and infertility in pregnant females. According to the National Park Service, brucellosis outbreaks have been reported in several western states, with a 2019 outbreak in Wyoming’s Yellowstone National Park affecting over 120 animals.

Vaccination and Management

To manage brucellosis in pronghorn populations, wildlife managers and veterinarians often use a combination of vaccination and population control measures. The most effective vaccination strategy is to vaccinate pregnant females in the fall, typically 4-6 weeks before calving, to provide protection to both the mother and her offspring. In areas where brucellosis is present, managers may also use population control measures such as culling infected animals and relocating healthy ones to disease-free areas.

Surveillance and Monitoring

Regular surveillance and monitoring are crucial to detecting and managing brucellosis in pronghorn populations. Wildlife managers and veterinarians use a variety of methods to monitor pronghorn populations, including blood sampling, PCR testing, and serology testing. By identifying infected animals early, managers can develop targeted disease management strategies to prevent the spread of brucellosis and protect both the animals and human communities.
