Ecology of Virus Transmission in Commensal Bats

The dynamics of rabies transmission in bat populations that roost and live within cities is being investigated using Fort Collins, Colo., and big brown bats (Eptesicus fuscus) as the case study. USGS biologists are working on this project in collaboration with Colorado State University, the Centers for Disease Control and Prevention, and the More...

Newly Identified Fungus Implicated in White-Nose Syndrome in Bats: Mysterious Bat Disease Decimates Colonies in the Northeast

It has been estimated that over 100,000 bats have died in the northeast due to a mysterious white fungus called White-Nose Syndrome (WNS). Scientists are finding within caves and mines a large number of bats with a white fungus on their muzzles and other parts of their bodies. It is uncertain as to how this fungus is being transmitted and its More...

White-Nose Syndrome Mystery: Something Is Killing Our Bats

Tens of thousands of hibernating bats died this winter in the northeast, and for unknown reasons. In and around caves and mines in eastern and upstate New York, Vermont, western Massachusetts, and northwestern Connecticut, biologists found sick, dying and dead bats in unprecedented numbers. In just eight of the affected New York caves, mortality More...

White-Nose Syndrome Threatens the Survival of Hibernating Bats in North America

During the winter of 2006 or 2007, an affliction of unknown origin dubbed "White-Nose Syndrome" (WNS) began devastating colonies of hibernating bats in a small area around Albany, New York. Colonies of hibernating bats were reduced 81-97 percent at the affected caves and mines that were surveyed. Since then, White-Nose Syndrome has been detected More...

Bat White-Nose Syndrome: An Emerging Fungal Pathogen?

The condition in bats known as white-nose syndrome (WNS) was first noted among dead and hibernating bats found in caves near Albany, New York, by the New York State Department of Environmental Conservation beginning in February 2007. Affected bats appeared to have a white substance on their heads and wings. In early 2008, "white-nosed" bats were More...
