White-nose syndrome (WNS) is an emergent disease of hibernating bats that has spread from the northeastern across United States at an alarming rate.
Since the winter of 2007-2008, millions of insect-eating bats in 40 states and eight Canadian provinces (as of July 2023) have died from this devastating disease. Bat population declines are expected to have substantial impacts on the environment and agriculture. Bats eat insects that damage crops and spread disease. Consumption of insects by bats saves farmers billions of dollars in pest control services annually.
White-nose syndrome is caused by a fungus, Pseudogymnoascus destructans, that infects skin of the muzzle, ears, and wings of hibernating bats. Field signs of WNS can include excessive or unexplained mortality at a hibernaculum; visible white fungal growth on the muzzle or wings of live or freshly dead bats; abnormal daytime activity during winter months or movement toward hibernacula openings; and severe wing damage in bats that have recently emerged from hibernation. Infected bats experience a cascade of physiologic changes that result in weight loss, dehydration, electrolyte imbalances, and death. To determine conclusively if bats are affected by white-nose syndrome, scientists must examine a skin specimen to look for a characteristic microscopic pattern of skin erosion caused by P. destructans. Please see below for guidance on sample collection and submission for diagnostic services.
The U.S. Geological Survey (USGS) has been a leading contributor to the interagency response to WNS since 2008 and continues to provide ongoing scientific support to these efforts by performing fundamental research on bat ecology, fungal biology, and WNS epidemiology and pathology.

White-nose syndrome in North American bats - U.S. Geological Survey updates
White-nose syndrome is a devastating wildlife disease that has killed millions of hibernating bats. This disease first appeared in New York during 2007 and has continued to spread at an alarming rate from the northeastern to the central United States and throughout eastern Canada. The disease is named for the fungus Pseudogymnoascus destructans, which often appears white when it infects the skin o

First detection of bat white-nose syndrome in western North America
White-nose syndrome (WNS) is an emerging fungal disease of bats caused by Pseudogymnoascus destructans. Since it was first detected near Albany, NY, in 2006, the fungus has spread across eastern North America, killing unprecedented numbers of hibernating bats. The devastating impacts of WNS on Nearctic bat species are attributed to the likely introduction of P. destructans from Eurasia to naive ho

Use of multiple sequencing technologies to produce a high-quality genome of the fungus Pseudogymnoascus destructans, the causative agent of bat White-Nose syndrome
White-Nose syndrome has recently emerged as one of the most devastating wildlife diseases recorded, causing widespread mortality in numerous bat species throughout eastern North America. Here, we present an improvised reference genome of the fungal pathogen Pseudogymnoascus destructans for use in comparative genomic studies.

Optimized methods for total nucleic acid extraction and quantification of the bat white-nose syndrome fungus, Pseudogymnoascus destructans, from swab and environmental samples
The continued spread of white-nose syndrome and its impacts on hibernating bat populations across North America has prompted nationwide surveillance efforts and the need for high-throughput, noninvasive diagnostic tools. Quantitative real-time polymerase chain reaction (qPCR) analysis has been increasingly used for detection of the causative fungus, Pseudogymnoascus destructans, in both bat- and e

Effects of wind energy generation and white-nose syndrome on the viability of the Indiana bat
Wind energy generation holds the potential to adversely affect wildlife populations. Species-wide effects are difficult to study and few, if any, studies examine effects of wind energy generation on any species across its entire range. One species that may be affected by wind energy generation is the endangered Indiana bat (Myotis sodalis), which is found in the eastern and midwestern United State

Estimating the short-term recovery potential of little brown bats in the eastern United States in the face of White-nose syndrome
White-nose syndrome (WNS) was first detected in North American bats in New York in 2006. Since that time WNS has spread throughout the northeastern United States, southeastern Canada, and southwest across Pennsylvania and as far west as Missouri. Suspect WNS cases have been identified in Minnesota and Iowa, and the causative agent of WNS (Pseudogymnoascus destructans) has recently been detected in

Direct detection of fungal siderophores on bats with white-nose syndrome via fluorescence microscopy-guided ambient ionization mass spectrometry
White-nose syndrome (WNS) caused by the pathogenic fungus Pseudogymnoascus destructans is decimating the populations of several hibernating North American bat species. Little is known about the molecular interplay between pathogen and host in this disease. Fluorescence microscopy ambient ionization mass spectrometry was used to generate metabolic profiles from the wings of both healthy and disease

The fungus Trichophyton redellii sp. nov. causes skin infections that resemble white-nose syndrome of hibernating bats
Before the discovery of white-nose syndrome (WNS), a fungal disease caused by Pseudogymnoascus destructans, there were no reports of fungal skin infections in bats during hibernation. In 2011, bats with grossly visible fungal skin infections similar in appearance to WNS were reported from multiple sites in Wisconsin, USA, a state outside the known range of P. destructans and WNS at that time.

Nonlethal screening of bat-wing skin with the use of ultraviolet fluorescence to detect lesions indicative of white-nose syndrome
Definitive diagnosis of the bat disease white-nose syndrome (WNS) requires histologic analysis to identify the cutaneous erosions caused by the fungal pathogen Pseudogymnoascus [formerly Geomyces] destructans (Pd). Gross visual inspection does not distinguish bats with or without WNS, and no nonlethal, on-site, preliminary screening methods are available for WNS in bats. We demonstrate that long-w

White-nose syndrome initiates a cascade of physiologic disturbances in the hibernating bat host
Background
The physiological effects of white-nose syndrome (WNS) in hibernating bats and ultimate causes of mortality from infection with Pseudogymnoascus (formerly Geomyces) destructans are not fully understood. Increased frequency of arousal from torpor described among hibernating bats with late-stage WNS is thought to accelerate depletion of fat reserves, but the physiological mechanisms that
