Terrestrial Wildlife Diseases

Bat Research Research collaboration: Brian Reichert (FORT), Anne Ballmann (NWHC), Jeremy Coleman (USFWS), Paul Cryan (FORT), Wayne Thogmartin (UMESC), and Katherine Irvine (NOROCK) White-nose syndrome is caused by the fungal pathogen Pseudogymnoascus destructans (Pd), which has decimated hibernating bat populations across North America since it emerged 10 years ago in New York. While diagnostic...

Bat Research Research collaboration: Robin Russell (NWHC), Tonie Rocke (NWHC), Wayne Thogmartin (UMESC), Evan Grant (EESC) White-nose syndrome is a fungal disease devastating cave-hibernating bat species ( Myotis spp.) in the eastern United States. Several mitigation tactics have been proposed to alleviate the effects of white-nose syndrome on bats including probiotics and vaccination. Questions...

Bat Research Research collaboration: Winifred Frick (Bat Conservation International), Brian Reichert (FORT), Theodore Weller (US Forest Service), Wayne Thogmartin (UMESC) and the North American Bat Colony Count Consortium We quantify vulnerability of bat species in North America to target and prioritize management actions toward species and habitats that are most at risk from impacts from White...

Harmful algal blooms (HABs) have the potential to harm fish and wildlife, domestic animals, livestock, and humans through toxin production or ecological disturbances such as oxygen depletion and blockage of sunlight.

Reporting of wildlife diseases is important to build situational awareness regarding wildlife health, build national and global knowledge capacity, increase coordination among agencies, and integrate wildlife health data into other surveillance frameworks .

Disease is a major threat facing amphibian and reptile populations around the world. Our research addresses interactions between pathogens, the environment, and hosts to better understand ways to prevent the spread of disease.

Chronic wasting disease (CWD) is an emerging infectious disease that is fatal to free-ranging and captive animals in Cervidae, the deer family. CWD is one member of a family of diseases called transmissible spongiform encephalopathies (TSEs), and is thought to be caused by prions. CWD is the only TSE known to affect free-ranging wildlife.

Introduced mosquito-borne avian diseases, avian pox and avian malaria, are key limiting factors for endemic Hawaiian forest birds and are, in part, likely responsible for past extinctions and the continued decline of extant species populations. In the last 40 years on the island of Kaua‘i a number of species have become increasingly rare and several are now presumed extinct. Coinciding with these...

Avian influenza is a viral disease caused by various strains of avian influenza viruses that can be classified as low pathogenic avian influenza (LPAI) or highly pathogenic avian influenza (HPAI). It remains a global disease with potential high consequence with the potential to threaten wildlife, agriculture, and human health.

The USGS National Wildlife Health Center (NWHC) provides the following index of wildlife disease information resources as a starting point to learn about selected wildlife diseases.

CWD is a degenerative neurological disease caused by infectious proteins called prions. Although documented cases are invariably fatal, infected elk commonly survive for several months or longer, passing prions directly to other individuals and into the environment, where they bind to surfaces or soils and can persist for years. CWD reached Wind Cave National Park about 1997 and rapidly became the...

Botulism is a natural toxin produced by a bacterium ( Clostridium botulinum ) commonly found in the soil. There are several types of botulism toxin some of which can affect humans who eat improperly canned foods. Birds get their own kind of botulism (Type C in Hawaii) that does not affect humans. Botulism type C is concentrated in aquatic invertebrates that filter feed sediments or water. When...
