USGS is the lead Federal agency for wildlife disease research and surveillance. Our wildlife health capabilities provide research, information, and technical assistance needed to manage wildlife through disease events. Congress and our partners rely on our science to make informed decisions about fish and wildlife disease policy, planning and management.

Hot new imagery of wintering bats suggests a group behavior for battling white-nose syndrome

Hot new imagery from temperature-sensing cameras suggests that bats who warm up from hibernation together throughout the winter may be better at surviving white nose syndrome, a disease caused by a cold-loving fungus ravaging insect-eating bat populations in the United States and Canada.

Sylvatic Plague

Sylvatic plague is a flea-borne bacterial disease of wild rodents. Humans, pets, and wildlife can be afflicted with this disease.  Prairie dogs are highly susceptible to plague and are the primary food source of the highly endangered black-footed ferret, which is also susceptible to the disease. Sylvatic plague can decimate prairie dog colonies (90% or greater mortality rates), resulting in...

Coral Diseases

Coral disease is now one of the major causes of reef degradation and coral mortality. First reported on reefs in the Florida Keys and Caribbean in the 1970s, black band disease was first recorded in Hawaii in 1994.

Sea Star Wasting Disease

Sea stars are dying off at dramatic rates across the West Coast from Baja California in Mexico to Alaska. The wasting disease that is affecting sea stars also is not specific to one species: more than 20 sea star species have been affected so far.

Vector-borne Disease Research

The Challenge: Lyme disease, which is caused by a tick-transmitted spirochete, is the most common vector-borne disease in North America, with about 300,000 cases each year. Most cases occur in the northeastern and north central U.S., with relatively few in the south, even though the vector tick is present in all of these regions. The purpose of this research is to elucidate the ecological...

Highly Pathogenic Avian Influenza Seaduck Challenge Study

The Challenge: The susceptibility and pathogenesis of highly pathogenic avian influenza virus (HPAI) has not been characterized in numerous duck species, especially diving ducks (genera Melanitta, Aythya, and Oxyura), some of which migrate across the continental US. The few studies available (on Tufted duck, Aythya fuligula) suggest that they may shed high amounts of virus, but it is unclear...

American Black Duck and Threat of Avian Influenza

The Challenge: The genomic revolution is giving wildlife biologists new tools to assess the role of wildlife in spreading diseases that affect human populations.   Peptide arrays are a high throughput technology that gives unprecedented breadth and depth of information about the immune system.  We are using peptide arrays to assess the immune responses of Chesapeake Bay waterfowl to avian...

Disease Resistance of Wildlife Species: how the immune system evolves and adapts

The Challenge: In an era when emerging infectious diseases are steadily increasing, human populations are exposed to virulent new pathogens.  Insight into the human system can be gained from understanding the variety of immune adaptations of wildlife species.  The vertebrate immune system is not static.  Rather, it involves in response to the environment.

Avian Influenza Surveillance in Waterfowl in the Atlantic Flyway

The Challenge: In December of 2014, a novel strain of highly pathogenic avian influenza (HPAI) caused an outbreak in poultry on the West coast of the United States. From there, the virus progressed steadily eastward, causing $3.3 billion in economic losses in addition to 50 million chickens or turkeys dying or being depopulated. While the primary mode of spread appears to be via the poultry...

Pathogens in the Aquatic Environment – Waterfowl, Avian Influenza

The Challenge: Changes in aquatic ecosystems related to climate change phenomena or other anthropogenically based environmental stressors have significant impact on the dynamics of the host-pathogen-environment relationship, often with surprising results. Therefore, biosurveillance of the aquatic environment for pathogens of significance to aquatic and terrestrial wildlife, as well as to...

USGS Wild Bird Avian Influenza Program – Studies from Endemic Regions of Eurasia

The Challenge: Following outbreaks of highly pathogenic avian influenza (HPAI) in Eurasia, many researchers have attempted to determine how this virus spreads across the landscape. Unfortunately, prior to this work, most studies on HPAI movements were based on virology data alone, and no information on host ecology. Beginning in 2007, USGS Patuxent Wildlife Research Center (PWRC) and Western...

Tracking Domestic Ducks through the Market Chain in China via Telemetry

The Challenge: Highly pathogenic avian influenza viruses (HPAI) of certain subtypes primarily infect poultry, causing disease outbreaks and negative socio-economic impacts on poultry farming depending on the characteristics of biosecurity and the virus strain. HPAI viruses seem to be adapted to artificial ecosystems including poultry farming, free-ranging duck production, and live bird markets...

An Eco-immunological Study of Chesapeake Bay Waterfowl

The Challenge: The health of the abundant waterfowl species of Chesapeake Bay has become a major concern due to the spread of Avian Influenza (AI) across North America and the role of waterfowl as a vector of AI. For decades, the health of the Bay’s waterfowl has been affected by the degradation of water quality and food supply due to industrial contaminants,agricultural run-off, pollution...

Hibernating little brown bat

little brown bat (Myotis lucifugus) with white-nose syndrome hibernating in a Virginia cave during late spring of 2016. Patches of the fungus that causes white-nose syndrome can be seen growing out of the skin (white areas) near the nose and across the folded wing skin of this bat.  Spherical drops of water condensation coat the bat's outer fur, a normal condition that...
