Invasive Pathogens
Invasive Pathogens
Invasive pathogens include diseases and disease-causing microorganisms of plants and animals that can spread rapidly and have significant impacts across the U.S. USGS research is addressing numerous diseases in both plants and animals and leading development efforts in advanced tools such as environmental DNA (eDNA) and vaccine technologies to assist in prevention and early detection.

Using Robots in the River: Biosurveillance at USGS streamgages
For more than a decade, researchers around the world have shown that sampling a water body and analyzing for DNA (a method known as eDNA) is an effective method to detect an organism in the water. The challenge is that finding organisms that are not very abundant requires a lot of samples to locate this needle in a haystack. Enter the "lab in a can", the water quality sampling and processing robot...
Population Demographic Models for the Conservation of Endangered Indiana Bats at Risk to White-Nose Syndrome
Bat Research Bats are nocturnal, flying mammals that eat insects or fruits, pollinate flowers, distribute seeds, and are important to many ecosystems. Across North America there are 45 species of bats, many of which are threatened or endangered. One species of federally endangered bat, the Indiana bat (Myotis sodalis), is a medium-sized, gray, black, or chestnut brown bat living primarily in...
Ecological Investigations of White-Nose Syndrome in Bats
White-Nose Syndrome (WNS) is a devastating disease that threatens the survival of hibernating bats in North America. Since first documented in the winter of 2005/2006, WNS has spread from a very small area of New York across at least two thousand kilometers in half or more of states and provinces in the U.S. and Canada. Over five million bats are estimated to have died during the past decade from...
External Microbiota of Bats as Potential Bio-control Against Wildlife Diseases
White-nose syndrome (WNS) and/or Pseudogymnoascus destructans (P.d.), the causal agent, has spread westward across 26 states and 5 provinces within the eastern United States and Canada, respectively, over a short period of time. Since its discovery there has been a search to stop the spread of this disease that has killed millions of hibernating bats in its wake. Recent collaborative work by FORT...
