White-nose syndrome (WNS) is a condition associated with an unprecedented bat mortality event in the northeastern United States. Since the winter of 2006*2007, bat declines exceeding 75% have been observed at surveyed hibernacula. Affected bats often present with visually striking white fungal growth on their muzzles, ears, and/or wing membranes. Direct microscopy and culture analyses demonstrated that the skin of WNS-affected bats is colonized by a psychro-philic fungus that is… 

White-nose syndrome: is this emerging disease a threat to European bats?

White-Nose Syndrome in Hibernating Bats

Molecular investigations revealed a single clonal genotype for North America, while European isolates diversified, providing strong support for the hypothesis of an introduction of Pd from Europe into a naive bat population in North America.

Wing pathology of white-nose syndrome in bats suggests life-threatening disruption of physiology

The unique physiological importance of wings to hibernating bats in relation to the damage caused by G. destructans is reviewed and it is proposed that mortality is caused by catastrophic disruption of wing-dependent physiological functions.

Histopathology Confirms White-Nose Syndrome in Bats in Europe

The results, based on histopathology, show the presence of white-nose syndrome in Europe, and two bats found dead in March 2010 with geomycosis in the Czech Republic had characteristics resembling Geomyces destructans infection in bats confirmed withwhite-nosed syndrome in US hibernacula.

Experimental infection of bats with Geomyces destructans causes white-nose syndrome

It is demonstrated that exposure of healthy little brown bats to pure cultures of G. destructans causes white-nose syndrome and that the recent emergence of WNS in North America may represent translocation of the fungus to a region with a naive population of animals.

White-Nose Syndrome in Bats

A synthesis of the current state of knowledge on white-nose syndrome, including disease mechanisms, disease ecology, global distribution and conservation and management efforts is presented.

Fungal Disease and the Developing Story of Bat White-nose Syndrome

The unexpected emergence of WNS, the rapidity with which it has spread, and its unprecedented severity demonstrate both the impacts of novel fungal disease upon naive host populations and challenges to effective management of such diseases.

Geomyces destructans sp. nov. associated with bat white-nose syndrome.

Based on rRNA gene sequence (ITS and SSU) characters the fungus is placed in the genus Geomyces, yet its distinctive asymmetrically curved conidia are unlike those of any described Geomyce species.

White-nose syndrome (WNS) is a cutaneous fungal disease of hibernating bats associated with a novel Geomyces sp. fungus. Currently, confirmation of WNS requires histopathologic examination. Invasion



Spread of Chytridiomycosis Has Caused the Rapid Global Decline and Extinction of Frogs

It is important for the scientific community and conservation agencies to recognize and manage the threat of chytridiomycosis to remaining species of frogs, especially those that are naive to the pathogen.

Aerial Transport of Keratinaceous Substrate and Distribution of the Fungus Geomyces pannorum in Antarctic Soils

The Antarctic soil fungus Geomyces pannorum, which is able to utilize keratin-based substrates, was also present in aerobiological samples on Signy Island, suggesting that these birds may act as vectors for the transport of microorganisms between Antarctica and more northern landmasses.

Two new species of Pseudogymnoascus with Geomyces anamorphs and their phylogenetic relationship with Gymnostellatospora

Two new psychrophilic Pseudogymnoascus species with Geomyces anamorphs are described from a Sphagnum bog in Alberta, Canada. Pseudogymnoascus appendiculatus has long, branched, orange appendages and
