Dermatomycoses due to Trichophyton violaceum are described in Mediterranean Countries, North Africa and in the Horn of Africa where T. soudanense is present too, but it was rare until few years ago in Italy. Aim of the present study was to evaluate an Italian multicenter 9 year (2005-2013) experience concerning these re-emerging pathogens. Fifty three fungal strains were sent from clinical laboratories to the Medical Mycology Committee (CoSM)--Italian Association of Clinical Microbiology (AMCLI) for mycological confirmation. Strains were identified as T. violaceum (23) and T. soudanense (30) by phenotypic and genotypic methods. These dermatophytes present epidemiological (high rate of inter-human transmission, high risk among adopted children coming from countries of either the Horn of Africa or Sub-Saharan Africa also in outbreaks of tinea capitis) and clinical peculiarities (reduced alopecia, presence of exudative lesions) confirming the originality of these "imported" dermatophyte infections.
由紫色毛癣菌引起的皮肤癣菌病在地中海国家、北非以及索马里半岛都有报道，在这些地区苏丹毛癣菌也有存在，但直到几年前在意大利还很罕见。本研究的目的是评估意大利多中心9年（2005 - 2013年）关于这些重新出现的病原体的经验。53株真菌菌株从临床实验室被送至医学真菌学委员会（CoSM）——意大利临床微生物学协会（AMCLI）进行真菌学确认。通过表型和基因型方法将菌株鉴定为紫色毛癣菌（23株）和苏丹毛癣菌（30株）。这些皮肤癣菌呈现出流行病学（人际传播率高，来自索马里半岛或撒哈拉以南非洲国家的领养儿童在头癣暴发中风险高）和临床特点（脱发减少、存在渗出性损害），证实了这些“输入性”皮肤癣菌感染的独特性。
