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.

Rabies outbreak in captive big brown bats (Eptesicus fuscus) used in white-nose syndrome vaccine trial

An outbreak of rabies occurred in a captive colony of wild-caught big brown bats (Eptesicus fuscus). Five of 27 bats exhibited signs of rabies virus infection 22–51 d after capture or 18–22 d after contact with the index case. Rabid bats showed weight loss, aggression, increased vocalization, hypersalivation, and refusal of food. Antigenic typing...

Avian influenza virus prevalence in marine birds is dependent on ocean temperatures

Waterfowl and shorebirds are the primary hosts of influenza A virus (IAV), however, in most surveillance efforts, large populations of birds are not routinely examined; specifically marine ducks and other birds that reside predominately on or near the ocean. We conducted a long-term study sampling sea ducks and gulls in coastal Maine for IAV and...

Chronic wasting disease—Research by the U.S. Geological Survey and partners

IntroductionChronic wasting disease (CWD) is the only transmissible spongiform encephalopathy, a class of invariably fatal neurodegenerative mammalian diseases associated with a misfolded cellular prion protein found in wild free-ranging animals. Because it has a long incubation period, affected animals in Cervidae (the deer family; referred to as...
