This dataset includes skin temperatures of twelve Tadarida brasiliensis held in environmental chambers maintained at 7.7 (SD 0.9) °C and 91.8 (SD 0.8) % relative humidity to induce and support hibernation for up to 3 months. Bats were randomly assigned to infected and control groups at the start of the experiment and infected with conidia of Pseudogymnoascus destructans or a sham treatment (negative control). An iBBat temperature logger (Alpha Mach, Ste-Julie, Quebec, Canada) was attached to the dorsal surface of each bat and programmed to record skin temperature every 15 minutes until the end of the experiment when the bat died or was euthanized.
This work is part of an experimental trial investigating the effects of microclimate conditions of temperature and humidity on a fungal pathogen, Pseudogymnoascus destructans (Pd), that causes white-nose syndrome (WNS) disease in hibernating bats. As part of the trial, tri-colored bats (Perimyotis subflavus) were exposed to Pseudogymnoascus destructans (Pd) and allowed to hibernate in chambers with a variety of temperature and humidity conditions. Bats were euthanized after 83 days. A portion of the wing was rolled around dental wax dowels, fixed in 10% neutral buffered formalin, processed and stained with periodic acid-Schiff, and assessed by light microscopy for evidence of fungal infection. Three types of cutaneous...
Temperature-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 all isolates displayed an intermediate peak with rapid decline in performance above the peak. Optimal temperatures for growth were between 12.5 and 15.8 degrees C, and the upper critical temperature for growth was between 19.0 and 19.8 degrees C. Growth rates varied across isolates, irrespective of geographic origin, and above...
