Geomyces destructans, phenotypic features of some Czech isolates
نویسندگان
چکیده
The microscopic fungus Geomyces destructans is a psychrophilic dermatophyte causing since 2006 a serious bat disease in North America called white-nose syndrome (WNS). In Europe, G. destructans has also been recorded, however less commonly and without striking lethal effects. Currently, seven isolates of G. destructans isolated from greater mouse-eared bat (Myotis myotis) from four localities are maintained in the Culture Collection of Fungi (CCF) in Prague. Growth tests at 12 and 15 °C on eight agar media demonstrated that the fungus grows somewhat faster at 12 °C than at 15 °C. Good growth was observed on nutrient rich media. No further isolates of G. destructans were recovered during screening of bat-associated environments.

Clonal Genotype of Geomyces destructans among Bats with White Nose Syndrome, New York, USA
The dispersal mechanism of Geomyces destructans, which causes geomycosis (white nose syndrome) in hibernating bats, remains unknown. Multiple gene genealogic analyses were conducted on 16 fungal isolates from diverse sites in New York State during 2008-2010. The results are consistent with the clonal dispersal of a single G. destructans genotype.
متن کاملA culture-based survey of fungi in soil from bat hibernacula in the eastern United States and its implication for detection of Geomyces destructans, the causal agent of bat white-nose syndrome
The recent emergence of white-nose syndrome (WNS), a fungal disease causing unprecedented mortality among hibernating bats of eastern North America, has revealed a knowledge gap regarding fungal communities associated with bats and their hibernacula. We used culture-based techniques to investigate the diversity of fungi in soil samples collected from 24 bat hibernacula in the eastern United Sta...

متن کاملTemperature-Dependent Growth of Geomyces destructans, the Fungus That Causes Bat White-Nose Syndrome
White-nose syndrome (WNS) is an emergent disease estimated to have killed over five million North American bats. Caused by the psychrophilic fungus Geomyces destructans, WNS specifically affects bats during hibernation. We describe temperature-dependent growth performance and morphology for six independent isolates of G. destructans from North America and Europe. Thermal performance curves for ...
متن کاملIncreasing Incidence of Geomyces destructans Fungus in Bats from the Czech Republic and Slovakia
BACKGROUND White-nose syndrome is a disease of hibernating insectivorous bats associated with the fungus Geomyces destructans. It first appeared in North America in 2006, where over a million bats died since then. In Europe, G. destructans was first identified in France in 2009. Its distribution, infection dynamics, and effects on hibernating bats in Europe are largely unknown. METHODOLOGY/PR...
