“…The incidence of T. tonsurans infection is dynamically changing in various parts of the world 22. Although T. tonsurans rarely occurred in Iran,23 in 1995, it began to spread sporadically in Tehran and since then it has dramatically increased throughout Iran.…”

Background:In recent years, skin diseases in wrestling have finally received the attention they deserve. Outbreaks of tinea corporis are often associated with sports involving extensive bodily contact; such sports include wrestling. Tinea corporis gladiatorum is primarily caused by Trichophyton tonsurans, infecting wrestlers at alarming rates. The management of skin infections in wrestlers and other athletes in sports involving skin-to-skin contact entails numerous challenges, from making an accurate diagnosis to determining eligibility for playing the sports. To control outbreaks, we conducted an epidemiologic investigation. The purpose of this article is to determine the prevalence of tinea corporis gladiatorum in wrestlers in Tehran, Iran.Materials and Methods:A study of dermatophytosis was carried out during the period of March 2004 to December 2005 on 612 mycological proven cases of dermatophytosis found in male wrestlers in Tehran. Mycological examination consisted of culturing of pathologic material followed by direct microscopic observation. Diagnosis was based on macroscopic and microscopic characteristics of the colonies.Results:T. tonsurans was the predominant dermatophyte, accounting for >90% of all tinea corporis gladiatorum isolates during the 2 year analysis. Tinea corporis gladiatorum was found to be more frequent in individuals between the ages of 10 and 20 years of age (72.7%). Wrestlers with tinea corporis gladiatorum were predominantly from wrestling clubs in southern and southeastern Tehran. Transmission of tinea corporis is primarily through skin-to-skin contact.Conclusion:Rapid identification and treatment of tinea corporis gladiatorum is required to minimize the disruption of team practices and competitions. Infection with dermatophytes can disqualify a wrestler from competing in matches, and thus, vigilant surveillance and rapid initiation of treatment is important to prevent the suspension of team practices and competitions.

“…violaceum ) are thought to be associated with high rates of asymptomatic carriage [13]. These organisms generally cause varied signs of overt infection (seborrheic dermatitis – similar to tinea capitis with a mild or absent inflammatory response) and lack host response, which make them good candidates for asymptomatic carriage [14]. Zoophilic organisms such as Microsporum canis and T .…”

A study of tinea capitis was carried out during October 1998, involving 8531 school children aged 6-14 years (4718 males and 3813 females), attending 12 primary schools located in urban, rural, and refugee camp communities in the Nablus district in the Palestinian Authority. A total of approximately 1389 of the school children aged 6-12 years (724 males and 665 females) were also surveyed on three occasions at 2-3 month intervals, over a 9-month period (October 1998-May 1999) using the hair brush technique, for prevalence of asymptomatic tinea capitis carriage. Twenty-three(0.27%) mycologically proven cases of tinea capitis were detected.

“…Trichophyton tonsurans is the main cause of tinea capitis in children. Outbreaks of tinea corporis are often associated with sports such as wrestling that involve extensive bodily contact [1–3]. One reason for the low frequency of infections in adults is the increased fungistatic action of triglycerides in sebum that occurs after puberty [4]; a second reason may be attributed to their distinctive life styles and activities.…”

An epidemic of tinea corporis caused by Trichophyton tonsurans among children (wrestlers) in Germany

An outbreak of tinea corporis due to Trichophyton tonsurans among 46 children (aged 7-17 years) was investigated. Most of them were wrestlers. Thirty-one strains were identified by conventional methods, but proved to be problematic in 15 isolates due to colony variation and reduced sporulation. They were identified as Trichophyton tonsurans by the use of molecular methods, for example, sequence comparison of the ribosomal internal transcribed spacer (ITS) region and polymerase chain reaction fingerprinting. No DNA polymorphisms were detected with any of the techniques used, suggesting clonal reproduction of the populations of the species and providing evidence for spatial and temporal stability of the lineage.
