Abstract

Introduction: Dermatophytes are fungi that can cause infections of the skin, hair & nails due to their ability to invade keratin. Dermatophytosis is the most common superficial fungal infection worldwide; it is common in tropics and subtropical regions. It may present in epidemic proportions in areas of high humidity.
Objective: The present study aimed to identify various species causing dermatophytosis & to determine the invitro susceptibility pattern against commonly used systemic antifungal agents in our tertiary care center. 
Material and Methods: A total of 149 samples were collected of infected skin, hair and nails in a period of 1 year from January 2020 to December 2020. Samples were collected under aseptic condition by skin scrapping, nail and hair clipping by using scalpel or forceps. Identification of the causative pathogen was done by performing slide culture, lacto-phenol cotton blue mount, hair perforation tests and urease tests. We adopted a newly developed agar based disk diffusion assay to test susceptibility of clinically isolated dermatophytes for antifungal susceptibility testing.
Results: Microbiological investigations revealed the presence of dermatophytic fungi in 71.8% of the samples. Trichophyton rubrum was the predominant pathogen isolated. The study showed Itraconazole to be most effective antifungal drugs against dermatophytes followed by terbinafine and fluconazole. 
Conclusions: Further intensive epidemiological and invitro antifungal susceptibility studies of dermatophytes are required which will have more public health significance.
