what is white nose syndrome？
White-nose syndrome is a disease that affects hibernating bats and is caused by an invasive, cold-loving fungus. The fungus grows on bats' skin, disturbing their hibernation and resulting in dehydration, starvation and often death.2021年4月21日
Considering this,What caused white-nose syndrome?
White-nose syndrome is caused by a fungus, Pseudogymnoascus destructans, that infects skin of the muzzle, ears, and wings of hibernating bats.
Correspondingly,Does white-nose syndrome affect humans?
WNS does not affect humans, but humans who visit caves play an unintentional part in spreading the fungus from cave to cave, as it can linger on clothing and gear. To reduce exposure of hibernating bat populations, authorities have closed many caves to recreational visits.
Accordingly,How do you treat white-nose syndrome?
In/near bat habitat (caves, abandoned mines, etc.)
- Avoid possible spread of WNS by humans by cleaning shoes and gear before and after entering caves. ...
- Leave bats alone. ...
- Obey signs: Don't enter closed or gated caves.
- Attend educational programs and volunteer opportunities in visitor centers.
Then,Can white-nose syndrome be cured?
Is there a cure for white-nose syndrome? No and because the fungus that causes white-nose syndrome is now established in North America, it is unlikely that it will go away. The focus is not on a single cure, but on several tools such as treating bats or changing environments that will help bats survive.
White-nose syndrome is an emergent disease of hibernating bats that has spread from the northeastern to the central United States at an alarming rate. Since the winter of 2007-2008, millions of insect-eating bats in at least 37 states and seven Canadian provinces have died from this devastating disease.
Current evidence indicates that WNS is not transmissible from bats to humans. Studies have shown that the fungus grows only at cold temperatures (41-68 degrees F) that are much lower than that of the human body. Also, no human infections have ever been documented after exposure to WNS-infected bats or caves.
There is no known cure for white-nose syndrome, but scientists worldwide are working together to study the disease and determine how it can be controlled. Bats eat insects and are critical pest controllers.
Why is Decontamination Important? Reduces the potential for big jumps across the continent. Slows the spread of disease. Prevents the arrival/spread of other potential exotic invaders in the future.
Does it affect all bats in North America? So far, white-nose syndrome appears to affect only bats that hibernate, which make up about half of the 45 bat species in the United States. Pollinating bats and long-distance migrants that don't hibernate don't seem to be affected.
EuropePseudogymnoascus destructans is believed to originate from Europe. The current P. destructans European distribution includes Austria, Belgium, Czech Republic, Denmark, Estonia, France, Germany, Hungary, the Netherlands, Poland, Romania, Slovakia, Switzerland, Turkey, Ukraine and the United Kingdom.
During annual bat population surveys, participating agencies collect swabs of bat skin, guano, hibernaculum sediment, and environmental substrate. If clinical signs of white-nose syndrome (WNS) are observed in the population, carcasses or wing biopsies from affected bats are collected for diagnostic testing.
