BackgroundDermatomycoses count to the most frequent dermatoses in Cambodia.ObjectivesThe aim of this survey was to investigate the occurrence of dermatophytes in this Southeast Asian country.MethodsFrom June 2017 to July 2018, skin scrapings were taken from 67 patients with superficial dermatophytosis for mycological diagnostics. Identification of dermatophytes was confirmed by sequencing of the ‘internal transcribed spacer’—(ITS) region of the rDNA, and the gene of the Translation Elongation Factor (TEF)‐1α.ResultsPatients were suffering from tinea corporis and tinea inguinalis/cruris 42/67 (63%), tinea capitis/faciei 14/67 (21%), tinea corporis/capitis/faciei 6/67 (9%), tinea manuum/pedis 2/67 (3%), tinea pedis 2/67 (3%) and tinea manuum 1/67 (1%). Both, by culture and/or PCR, a dermatophyte was detected in 52 (78%) out of 67 samples. Culture positive were 42 (81%) of 52, PCR positive were 50 (96%). The following dermatophytes were found: Trichophyton (T.) rubrum, 36/52 strains (69%, 29 by culture), T. mentagrophytes/T. interdigitale (TM/TI) 9/52 (17%, six by culture) and Microsporum (M.) canis 5/52 strains (10%, by culture). One strain of Nannizzia (N.) incurvata 1/52 (2%) and N. nana 1/52 (2%) was isolated. Based on sequencing, we demonstrated that two T. mentagrophytes strains out of the nine TM/TI represented the new ITS genotype XXV Cambodia. We found one T. mentagrophytes strain genotype VIII (now, reclassified as T. indotineae). This isolate was terbinafine resistant, and it exhibited the amino acid substitution Phe397Leu in the squalene epoxidase. Three strains of T. interdigitale genotype II* were isolated.ConclusionThis is the first survey on epidemiology of dermatophytes in Cambodia. Currently, T. rubrum represents the most frequent species in Cambodia. One Indian strain genotype VIII T. mentagrophytes was found. A highlight was the first description of the new T. mentagrophytes genotype XXV Cambodia.

Dermatofitozlar sıcak, nemli koşullar ve hijyenik olmayan ortamlarda çoğalarak deri, kıl, tırnak gibi yapıları etkileyen dermatofitlerden kaynaklanan yüzeysel mantar enfeksiyonlarıdır. Deri ve tırnakta görülen mantar enfeksiyonlarının dünya nüfusunun %20-25’ini etkilediği bilinmektedir. Kedi ve köpeklerde yaygın şekilde görülen dermatofit türü öncelikli olarak Microsporium canis (M. canis)’tir, ayrıca M. nanum, M. gypseum, Trichophyton mentagrophytes (T. mentagrophytes), T. terrestre gibi başka türlerin de taşıyıcılarıdır. Sağlıklı evcil kedi ve köpekler enfeksiyon rezervuarıdır ve genellikle M. canis’in taşıyıcılarıdır. Kontamine ortam ve hayvanlarla temas halinde olan insanlara bulaşarak deride ve baş bölgesinde mantar lezyonlarına neden olurlar. Vücutta herhangi bir hastalık, yetersiz beslenme, yüksek sıcaklık, nem, deride meydana gelen travma, ektoparazitlere bağlı deri hasarı, aşırı kalabalık ve hijyenik olmayan ortamlar dermatofitoz oluşturan risk faktörleridir. Belirtilen bilgiler ışığında bu derleme kapsamında başta veteriner hekimler olmak üzere, hayvancılıkla uğraşanlar, kedi-köpek sahipleri, veteriner teknisyenler ve mandıra işçileri de dahil riskli meslek grupları hakkında özlü bilgiler verildi. Türkiye ve Dünya’da son yıllara ait hayvanlar ve insanlardaki dermatofitoz prevalans verileri sunularak, hastalığın önemi ve mevcut durumuna değinildi. Ayrıca hastalığa ait klinik bulgular, tanı, sağaltım seçenekleri ile koruma ve kontrol yöntemlerine yönelik en son bilimsel kaynaklara dayanan özlü bilgiler sunuldu.

“…The authors found that 69% of keratinophilic fungi were isolated from soils where animals were present. 2 The authors also mentioned that residual animal fur and skin debris could act as soil enricher by providing organic matter for keratinophilic fungi. It is noteworthy that infected materials can maintain viable fungi for years, and therefore the presence of animals can significantly contribute to fungal shedding and persistence in the environment.…”
