Fungus Linked to White-Nose Syndrome Found in Nevada Bats

The Nevada Department of Wildlife (NDOW) has announced the detection of a fungus connected to white-nose syndrome in local bat populations. This fungus, known as Pseudogymnoascus destructans (Pd), was identified during standard monitoring efforts at Lake Mead National Recreation Area, as per NDOW’s press release.

While officials confirmed the presence of Pd in the samples taken, they clarified that none of the bats exhibited signs of white-nose syndrome, which is characterized by white fungal growths on the muzzle and wings of affected bats.

Dr. Mark Siegel, a senior medical analyst, noted that, thankfully, this disease does not pose a threat to humans unless it undergoes some mutation. He explained that the fungus spreads easily among bats during their hibernation period and that humans might inadvertently carry the spores from one cave to another, simply by walking through these environments.

“Fungi prefer cooler temperatures, which is why they thrive on bats while they’re hibernating. Unfortunately, the growth can interfere with their normal behavior, leading them to starve post-hibernation,” Siegel added.

White-nose syndrome was first identified in New York back in 2006 and has since spread across various states, finally reaching Nevada in recent years. Jonathan Young from NDOW expressed concerns over the implications of the fungus for bat conservation in the state, highlighting the importance of monitoring these bat populations closely.

Young mentioned, “We had anticipated the arrival of Pd in Nevada. Our ongoing studies have focused not only on this fungus but also on general trends in bat populations.” Authorities in the region are determined to tackle this issue, emphasizing measures such as sterilizing equipment, protecting habitats, and raising public awareness to minimize the spread of the fungus.

Moreover, officials are advising the public to avoid entering abandoned mines, as this could inadvertently lead to introducing the fungus into new bat habitats. Lake Mead National Recreation Area, which features diverse terrains including mountains, valleys, and canyons, covers over 1.5 million acres and is accessible year-round for visitors.
