摘要
Although no mass mortality has been recorded so far, the precise demographic effect of white-nose syndrome (WNS) on European bats still remains to be ascertained. Following the first isolation of P. destructans in Italy, further surveys were performed to assess the distribution of the fungus in NW Italy and its effects on bats. Data were collected from March 2019 to April 2020 at sites used for hibernation (six sites) and/or for reproduction (four sites) in Piedmont and Aosta Valley. A total of 138 bats, belonging to 10 species, were examined to identify clinical features possibly related to the fungal presence. Culture from swabs and the molecular identification of isolates confirmed the presence of P. destructans in bats from five sites, including two maternal roosts. Dermal fungal infiltration, the criterion to assess the presence of WNS, was observed in biopsies of bats belonging to Myotis blythii, M. daubentonii, M. emarginatus and M. myotis. This is the first report of the disease in Italy. The results suggest a greater susceptibility to the infection of the genus Myotis and particularly of M. emarginatus, possibly due to the long length of its hibernation period. Other fungal dermatophytes were also observed.

虽然到目前为止没有记录大规模死亡率,但是欧洲蝙蝠对白鼻综合征(WNS)的确切人口效应仍有待确定。在意大利第一次分离P. Destructans之后,进行了进一步的调查,以评估NW意大利真菌的分布及其对蝙蝠的影响。从2019年3月到4月20日在Piedmont和Aosta Valley的休眠(六个站点)和/或复制(四个站点)的网站上收集了数据。研究了属于10种物种的138个蝙蝠,以确定可能与真菌存在有关的临床特征。从拭子中的文化和分离物的分子鉴定证实了来自五个地点的蝙蝠的P. Destructans的存在,包括两种母体栖息。皮肤真菌渗透,评估WNS存在的标准,在属于肌球灰菌菌丝体Blythii,M.aubentonii,M. emarginatus和M. myotis的蝙蝠的活组织检查中观察到。这是意大利疾病的第一份报告。结果表明,对肌球灰肌肉的感染和尤其是M. emarginatus的感染更大的易感性,可能是由于其冬眠期的长长度。还观察到其他真菌皮肤细胞。
