Tinea gladiatorum as the major health concern among combat athletes and the most common cause of a decrease in the quality of their sports activities.
This study aimed to determine the molecular epidemiology of tinea gladiatorum in contact sports in Mazandaran Province, Northern Iran.
MATERIALS/METHODS: In total, 631 suspected athletes out of 4240 ones were screened for tinea gladiatorum in this cross-sectional study from May 2018 to February 2019. The infection was confirmed by direct microscopy and culture tests. The causative agents were identified by polymerase chain reaction-restriction fragment length polymorphism method on ITS rDNA region. The indoor environmental factors were evaluated in 81 sports halls in terms of temperature (°C), humidity (%), density (m /athletes) and the number of ventilators.
Tinea gladiatorum was confirmed in 6.5% (278/4240) of the athletes. Tinea corporis was the most common type of tinea (192/278; 69.0%), and 175 cases (27.7%) had more than one type of tinea. Moreover, Trichophyton tonsurans (192/203; 94.5%) was the most aetiological agent in all athletes followed by Microsporum canis (6/203; 2.9%), Trichophyton rubrum (2/203; 0.9%) and Trichophyton interdigitale (1/203; 0.4%). There was no significant association between the prevalence of tinea gladiatorum and the indoor environmental factors.
T. tonsurans is the most common agent of tinea gladiatorum in Northern Iran. Since no positive culture of dermatophyte was obtained from mats, it seems that skin-to-skin contact would be the most probable mode of transmission among wrestlers. Accordingly, periodical checkups should be considered by health care providers.
癣菌病作为格斗运动员的主要健康问题，也是降低其运动活动质量的最常见原因。
本研究旨在确定伊朗北部马赞达兰省接触性运动中癣菌病的分子流行病学。
材料/方法：在这项横断面研究中，我们于 2018 年 5 月至 2019 年 2 月对 4240 名疑似运动员进行了癣菌病筛查，共筛查出 631 名接触性运动员患有癣菌病。通过直接显微镜检查和培养试验确认感染。在 ITS rDNA 区域，采用聚合酶链反应-限制性片段长度多态性方法鉴定病原体。对 81 个运动场馆的室内环境因素进行了评估，包括温度（°C）、湿度（%）、密度（m/运动员）和通风扇数量。
6.5%（278/4240）的运动员确诊患有癣菌病。癣菌病最常见的类型是体癣（192/278；69.0%），175 例（27.7%）有超过一种类型的癣菌病。此外，在所有运动员中，毛癣菌（192/203；94.5%）是最主要的病原体，其次是犬小孢子菌（6/203；2.9%）、红色毛癣菌（2/203；0.9%）和红色毛癣菌（1/203；0.4%）。癣菌病的患病率与室内环境因素之间无显著关联。
在伊朗北部，毛癣菌是癣菌病最常见的病原体。由于从垫子上未获得阳性的真菌培养物，因此似乎运动员之间最有可能通过皮肤与皮肤接触传播。因此，卫生保健提供者应考虑定期进行检查。
