Bat-Killing Fungus Spreads West

Researchers have detected the fungus responsible for white-nose syndrome, which decimates bat populations, in Arkansas.

The fungus, Geomyces destructans, was found in two caves in the state, but so far there is no sign of the disease in the bat population.

“These are pretty far west occurrences,” Ann Froschauer of the US Fish and Wildlife Service told the BBC. “We do have one potential site further west in western Oklahoma, but these latest cases are the most western confirmed cases to date.”

WNS was first discovered in a cave in New York State in 2006 and has since swept through 22 other states and five Canadian provinces, killing almost 7 million bats along the way. The most obvious symptom of infected bats is a white fungus that grows on the nose, wings, ears, and tail, but the fungus also disturbs the animals during their hibernation, causing them to burn through their small fat reserve and often resulting in death.

There is currently no vaccine to protect uninfected bats. For the moment, researchers and officials are focused on slowing the spread of the disease. For example, some researchers are looking into the possibility of using abandoned military bunkers as sterile overwintering sites.
