What is white-nose syndrome caused by?

White-nose syndrome is caused by a fungus, Pseudogymnoascus destructans, that infects skin of the muzzle, ears, and wings of hibernating bats.

Can humans get white-nose syndrome?

Thousands of people have visited affected caves and mines since White-nose Syndrome (WNS) was first observed, and there have been no reported human illnesses attributable to WNS. We are still learning about WNS, but we know of no risk to humans from contact with WNS-affected bats.

Is there a cure?

Not yet. Some promising interventions are being researched, such as naturally occurring bacteria that seem to limit the growth of the white-nose fungus. However, these treatments need to be carefully tested before widespread release in the environment, to make sure they'll actually be helpful, and not cause more stress to either bats or the ecosystems in which they live.

Unattached microbes are moved from the lungs to the epiglottis by the _______ effect.
lisov135 [29]

Answer:

The unattached microbes are moved from lungs to epiglottis by the <u>mucociliary escalator effect.</u>

Explanation:

Mucociliary escalator, also known as mucociliary clearance, is one of the major defense mechanisms that protects the lungs. It describes the self-cleaning mechanism of the bronchi which are present in the lungs. The effectiveness of this mechanism depends on the properties of the produced mucus and on the quality and number of the cilia present in the lining of the airway.

Therefore, the unattached microbes are moved from lungs to epiglottis by the <u>mucociliary escalator effect.</u>
