Comparative study of direct polymerase chain reaction, microscopic examination and culture‐based morphological methods for detection and identification of dermatophytes in nail and skin samples

Abstract: The positive rates of dermatophytes isolated and identified by conventional methods are rather low. Moreover, clinical isolates sometimes show atypical morphology, and in such cases microscopic methods are not applicable for identification. The present study was performed to assess the utility of specific polymerase chain reaction (PCR)-based methods for Trichophyton rubrum and Trichophyton mentagrophytes as diagnostic tools for dermatophytoses. Both conventional morphological identification and specific PCR m… Show more

“…The infection is primarily caused by dermatophytes which may be the most common superficial mycosis. More than 10 % of the general population is infected with dermatophytes [1,2]. The incidence of tinea unguium has been sharply increasing in recent years due to the extensive use of immunosuppressive chemotherapy, a growing geriatric population, and an increasing number of immunocompromised patients [3].…”

“…The diagnosis must be made based on isolation of the organism from affected tissues and visualisation of tissue invasion by organisms with compatible morphology. However, it is very difficult to culture these agents (Kane et al, 1997;Uchida et al, 2009).…”

“…Aynı zamanda kültürde üreyen suşların tümü pan-dermatofi t nPCR ile dermatofi t olarak, T.rubrum/T.mentagrophytes'e özgül nPCR ile tür düzeyinde, aynı gün içinde ve ek teste gerek kalmadan tanımlanmıştır. Yapılan bazı çalışmalarda, benzer şekilde kültürde üremiş ancak tanımlanamamış suşların PCR ile kısa sürede ve doğru olarak tanımlandığı bildirilmiştir 5,10 . Turin ve arkadaşları 6 kültürde üretilen dermatofi tlerden ve kazıntı örneklerinden yapılan 18S rDNA'yı hedefl eyen PCR ile dermatofi t türlerinin ayrılamadığını, ITS bölgesini hedefl eyen PCR ile bu ayrımın yapılabildiğini; 20 örneğin 12'sinde kültürde üreme saptandığını, 10'unda PCR ile pozitif sonuç alındığını bildirmiştir.…”
