Contamination with the fungus Alternaria spp. is often considered to have originated from laboratory sources, which occasionally causes infection in immunocompromised patients, termed as phaeohyphomycosis. Here, we have reported a case of cutaneous alternariosis caused by Alternaria alternata. This diagnosis was based on microscopic examination and mycological culturing of patient's vesicular lesions, with the use of 5 molecular markers (namely, ITS, ATPase, Actin, rpb2, and tef1) for strain identification. We noted that Alternaria infection caused an increase in the serum level of (1–3)-β-D-glucan (BG) in the patients. To the best of our knowledge, no such finding has been reported in previously in the literature.

被真菌Alternaria spp污染。通常被认为是由实验室来源引起的，偶尔会在免疫功能低下的患者中引起感染，称为细菌性真菌病。在这里，我们报道了一例由链格孢菌引起的皮肤链球菌病。该诊断基于对患者水泡病变的显微镜检查和真菌培养，并使用5种分子标记（即ITS，ATPase，Actin，rpb2和tef1）进行菌株鉴定。我们注意到，链格孢菌感染导致患者血清中（1-3）-β-D-葡聚糖（BG）含量增加。据我们所知，以前的文献中没有报道过这种发现。
