最早记录的白鼻综合症病例来自2006年在纽约Schoharie县拍摄的蝙蝠照片。到2017年,至少有15种蝙蝠受到影响,其中包括4种濒危或受威胁物种。这种疾病迅速蔓延到33个美国州和7个加拿大省(2018年)。虽然大多数病例已在北美东部记录,但2016年在华盛顿州发现一只小棕色蝙蝠被感染。最初,真菌病原体被鉴定为Geomyces destructans,但后来被重新分类为相关物种Pseudogymnoascus destructans。真菌是一种嗜冷或冷爱的生物体,它的温度在39-59°F之间,当温度超过68°F时会停止生长。真菌通过蝙蝠之间或蝙蝠与受感染表面之间的直接接触传播。在冬眠冬季,白色的生长变得明显。 Pseudogymnoascus destructans感染蝙蝠翅膀的表皮,破坏动物的新陈代谢。受影响的蝙蝠会出现脱水,体脂减少和疤痕疤痕。死亡的原因通常是饥饿,因为感染会耗尽蝙蝠的冬季脂肪储备。在冬天存活的蝙蝠可能遭受翅膀伤害并且无法找到食物。

The earliest recorded cases of white nose syndrome were from bat photos taken in 2006 in Schoharie County, New York. By 2017, at least 15 species of bats will be affected, including four endangered or threatened species. The disease quickly spread to 33 US states and 7 Canadian provinces (2018). Although most cases have been recorded in eastern North America, a small brown bat was found to be infected in Washington State in 2016. Initially, the fungal pathogen was identified as Geomyces destructans, but was later reclassified as the related species Pseudogymnoascus destructans. A fungus is a psychic or cold-loving organism that has a temperature between 39 and 59 °F and stops growing when the temperature exceeds 68 °F. Fungi are transmitted by direct contact between bats or between bats and infected surfaces. During the winter of hibernation, the growth of white becomes apparent. Pseudogymnoascus destructans infects the epidermis of bat wings and destroys the animal’s metabolism. Affected bats experience dehydration, body fat loss and scar scarring. The cause of death is usually hunger, because the infection will deplete the bat’s winter fat reserves. Bats that survive in winter may suffer from wing damage and cannot find food.
