Aerial dispersal of propagules, an important mechanism of fungal spread, has not been sufficiently studied for skin-infecting fungi. Over a period of one year, we have monitored the distribution of dermatophytes in the air of Turin. We have also examined the related aleurioconidic and arthroconidic fungi, which share physiological and morphological characters with dermatophytes and are sometimes considered to cause similar infections. A viable volumetric collector was used. Samples were taken each month; each sample collected 9.6 m3 of air. The medium was Dermasel agar supplemented with cycloheximide and chloramphenicol. Thirty-two species were isolated, within the genera Aphanoascus, Arthrographis, Chrysosporium, Geomyces, Gymnoascus, Malbranchea, Myceliophthora, Myxotrichum, Ovadendron, Trichophyton. The total mycoflora load obtained was rather low throughout the year and particularly in the hottest months. Apart from T. rubrum and T. mentagrophytes, which are dermatophytes very frequently encountered in Turin, many of the species detected have known pathogenic potential and/or keratinolytic activity.
真菌繁殖体的空气传播是真菌传播的一种重要机制，但对于引起皮肤感染的真菌，这方面的研究还不够充分。在一年的时间里，我们监测了都灵空气中皮肤癣菌的分布情况。我们还检测了相关的粉孢子和关节孢子真菌，它们与皮肤癣菌具有相同的生理和形态特征，有时被认为会引起类似的感染。我们使用了一种可行的体积收集器。每月采集样本；每个样本收集9.6立方米的空气。培养基为添加了放线菌酮和氯霉素的皮肤癣菌琼脂。我们从隐球菌属、节孢子菌属、金孢子菌属、地丝菌属、裸囊菌属、马尔布兰奇霉属、毁丝霉属、粘丝菌属、卵枝霉属、毛癣菌属中分离出了32个菌种。全年获得的真菌总载量相当低，在最热的月份尤其如此。除了在都灵非常常见的红色毛癣菌和须癣毛癣菌外，检测到的许多菌种都具有已知的致病潜力和/或角蛋白分解活性。
