Bacteria on Bat Wings May Hold Key to combat White-Nose Syndrome
In a groundbreaking study, researchers from McMaster University are uncovering the potential of bacteria and fungi from bat wings to aid in the fight against white-nose syndrome (WNS), a devastating fungal disease that has decimated bat populations across North America. In <a href="http://www.world-today-news.com/storm-in-british-columbia-floods-and-landslides-in-canada/" title="Storm in British Columbia: Floods and landslides in Canada”>Lillooet, British Columbia, scientists are analyzing the microbiome of bats that have remained uninfected despite the presence of this lethal fungus, aiming to identify natural defenses and innovative treatments.
Investigating a Remarkable Microbiome
Led by Jianping Xu, a biology professor at McMaster University, the team captured and tested 76 bats, identifying thousands of previously unknown bacterial and fungal strains. This remarkable undertaking is aimed at understanding how the wing microbiome plays a critical role in bat health and susceptibility to WNS, caused by the cold-loving fungus Pseudogymnoascus destructans.
“We see a very high number of bat species in the Rockies and west of the Rockies,” explains Xu. “If there is a new frontier for preserving bat species, it will likely be found in western North America, yet we know very little about the wing microbiome of these bats.”
The Threat of White-Nose Syndrome
White-nose syndrome was first detected in New York in 2006, swiftly spreading across Canada and the U.S. Experts believe that the disease predominantly affects three smaller bat species: the little brown bat, northern long-eared bat, and the tricolored bat. These species have experienced population declines as steep as 90% in some regions due to the disease.
The fuzzy white growth associated with WNS disrupts hibernation and increases metabolic demand, leading to starvation when bats awaken and exhaust their fat reserves. This alarming trend has raised questions regarding conservation strategies and innovative solutions to counteract the ongoing crisis facing North American bats.
Unlocking Nature’s Potential
The revelation that Lillooet’s bat population shows no signs of WNS despite the surrounding environment being affected underscores the critical role of the microbiome in bat health. Xu’s research indicates that certain bacterial strains found on the wings may be instrumental in fending off the harmful fungus.
Through isolation efforts, researchers identified over 1,000 bacterial strains, narrowing it down to over a dozen strains demonstrating antifungal properties. Further combined testing of four strains revealed enhanced effectiveness against the fungus.
“To develop a powerful probiotic cocktail that will work and will have an effect against the fungus in nature, we must understand the microbiome of the bats,” adds Xu.
Probiotic Solutions in the Works
The goal is to refine a probiotic cocktail in collaboration with scientists from the Wildlife Conservation Society of Canada and Thompson Rivers University. This cocktail is one of several experimental treatments being aggressively tested within the scientific community, which also includes vaccines and fumigation methods aimed at mitigating the spread of WNS.
Over the past three years, the team has conducted trials in roosts across British Columbia and Washington State, yielding promising results. Xu affirms that any future decisions regarding restoration efforts for bat populations will rely heavily on regional knowledge of the wing microbiome, leading to more tailored probiotic solutions.
Implications for Technology and Conservation
The intersection of microbiology and wildlife conservation is unfolding in unprecedented ways, with potential implications extending beyond bats. Understanding microbial ecosystems can pave the way for groundbreaking treatments in various domains, from agriculture to public health. This innovative approach to biological science not only addresses the urgent issue of bat conservation but also demonstrates the broader impact of utilizing natural resources to combat disease.
The Path Forward
This research represents a beacon of hope for conservationists working tirelessly to protect vulnerable bat species from the grips of white-nose syndrome. As the microbial landscape of bat wings is unveiled, there are expectations for novel solutions that could alter the trajectory of these populations.
