Fish and Wildlife Disease

USGS is the lead Federal agency for free-ranging wildlife disease research and surveillance. Our capabilities enhance the understanding of wildlife disease ecology and epidemiology as well as inform the development of decision-support and control tools. USGS wildlife disease experts provide technical assistance as needed to manage wildlife disease and conduct cause-of-death investigations.

READI-Net: Providing Tools for the Early Detection and Management of Aquatic Invasive Species

The USGS has developed the Rapid environmental (e)DNA Assessment and Deployment Initiative & Network (READI-Net) to accelerate the implementation of environmental DNA (eDNA) analysis as a best practice for the early detection of aquatic biological threats. READI-Net provides tools and a strategy to collect and deliver early detection data for natural resource managers and public health protection...

Avian Malaria Genomic Research Project

Many factors including habitat destruction, invasive plants, non-native predators and competitors, and introduced diseases have decimated the diverse, endemic native forest bird community of Hawai‘i. In particular, avian malaria ( Plasmodium relictum), which is transmitted by the introduced southern house mosquito ( Culex quinquefasciatus), has caused dramatic declines and extinctions in many...

SARS-CoV-2 in Wildlife

As SARS-CoV-2, the virus that causes COVID-19 in humans, continues to spread globally, questions have emerged about the potential for humans to transmit the virus to North American wildlife, its potential effects on native wildlife populations, and the resultant possibility and consequences of establishing a persistent wildlife reservoir. Recent studies have detected SARS-CoV-2 in escaped or wild...

Field trials for testing of white-nose syndrome vaccine candidates

White-nose syndrome (WNS), caused by the fungus Pseudogymnoascus destructans (Pd), continues to decimate bat populations in North America, and efforts to develop treatment options have intensified. One potential method for controlling WNS is vaccination of bats with specific antigens to elicit a protective immune response.

Evaluating Transmission of Chronic Wasting Disease in the Environment

Chronic wasting disease (CWD) is a fatal disease of deer, elk, and moose and has been spreading in North America for the past two decades. The disease is spread by infected body fluids. Animals can become infected by coming into direct contact with a CWD-infected animal, or an infected animal can leave behind fluids (e.g., saliva, urine) that an uninfected animal will come into contact later...

Research in response to Florida’s emerging coral disease

Coral reefs are both ecologically and economically important, serving as nurseries for fisheries, protecting the coastline from storm surges, and generating income from tourism. Since 2014, a wide variety of corals have been dying from unexplained causes throughout South Florida with mortalities ranging from North Miami to the Florida Keys.

Development of SARS-CoV-2 vaccine to support black-footed ferret conservation

The SARS-CoV-2 virus is known to infect and cause severe disease, such as respiratory distress and death, in mustelids, including farm-raised mink ( Mustela  lutreola and  Neovison  vison) and domestic ferrets ( M. putorius). This raised concern that the virus may also pose a threat to endangered black-footed ferrets ( Mustela nigripes) managed in captivity for breeding and recovery purposes.
