Tinea capitis is a highly contagious infectious disease caused by dermatophytes. In Central Europe, it is mainly caused by zoophilic dermatophytes, as, for example Microsporum (M) canis or Trichophyton (T) mentagrophytes and increasingly by anthropophilic fungi. T tonsurans was commonly related to the Tinea gladiatorum, where transmission occurred between infected persons or via contaminated floors.
Reporting the transmission of this highly contagious dermatophyte for the first time via beard shaving and hairdressing in barber shops in Germany.
18 young male patients developed tinea capitis and/or barbae shortly after shavings of the beard and/or hair in a barber shop. Native, cultural and molecular diagnostics as well as tissue biopsies and resistance tests were performed of skin and hair samples.
In all samples, T tonsurans could be identified. The medical history and the clinical picture suggest a transmission through contaminated hairdressing tools. The patients were treated with terbinafine or itraconazole in combination with or exclusively with topical antimycotics.
The transmission and a resulting increase in the incidence of infections with T tonsurans may be due to shavings with direct skin contact of insufficiently disinfected hairdressing tools. This path of infection has already been observed in Africa and is now being described for the first time in Germany. Knowledge of the pathogen and its transmission ways are essential to interrupt the chain of infection.
头癣是一种由真菌引起的高度传染性传染病。在中欧，它主要由亲动物性真菌引起，例如犬小孢子菌（M）或须癣毛癣菌（T），并且越来越多地由亲人性真菌引起。T 壤传播体通常与体癣有关，在体癣中，感染的人或通过污染的地板传播。
首次报告在德国理发店通过刮胡子和理发传播这种高度传染性的真菌。
18 名年轻男性患者在理发店刮胡子和/或理发后不久患上头癣和/或须癣。对皮肤和头发样本进行了本地、文化和分子诊断以及组织活检和耐药性测试。
所有样本中均鉴定出 T 壤传播体。病史和临床表现提示通过污染的美发工具传播。患者接受了特比萘芬或伊曲康唑联合或单独外用抗真菌药物治疗。
T 壤传播体的传播和由此导致的感染发病率增加可能是由于未充分消毒的美发工具直接与皮肤接触的刮胡子引起的。这种感染途径已在非洲观察到，现在德国首次描述。了解病原体及其传播途径对于阻断感染链至关重要。
