Studies on microscopic technique and culture on Sabouraud's dextrose agar medium for diagnosis of dermatophytes infection

Abstract

Dermatophytoses (a fungal infection of the skin, hair and nail, usually caused by dermatophytes) constitutes an important public health problem because of its high prevalence and associated morbidity but not life-threatening. Three genera of dermatophytes are recognized based on the site and pattern of fungal invasion. Dermatophytes are the predominant pathogenic mould, but yeasts (especially Candida albicans) and non-dermatophytic moulds may also be implicated. For accurate diagnosis of dermatophytoses requires microscopic demonstration and isolation and identification by culture. This study evaluates the usefulness of microscopic technique and culture for the isolation and identification of dermatophytes from clinical samples. Thirty samples were included in this study for detection of fungal elements by both methods but sensitivity of microscopic demonstration and culture were 60.0% and 66.7% respectively. As the sensitivity of microscopic demonstration (60.0%) is almost equal to the isolation and identification rate (66.7%), requires further evaluation in large scale as its ready to use format makes the application and microscopy much easier and faster.DOI: http://dx.doi.org/10.3329/kyamcj.v3i1.13658 KYAMC Journal Vol. 3, No.-1, June 2012 pp.235-238

Prevalence of Dermatophytic Infection and Detection of Dermatophytes by Microscopic and Culture Methods

“…Many studies have investigated the prevalence of dermatophytosis in different regions of the world including Bangladesh. [10][11][12][13] The aim of this study was to determine the prevalence of dermatophytic infections and diagnosis by microscopy and culture methods in Gazipur, Bangladesh.…”

Evaluation of Antifungal Effect of Silver Nanoparticles Against Microsporum canis, Trichophyton mentagrophytes and Microsporum gypseum

“…Transmissibility from infected humans or animals to human is one important public health problem caused by dermatophyte species (24). In some cases, treatment of the disease with the current therapeutic agents can result in the damage of host tissues due to the similarity between eukaryotic cells in human and fungi structure, emergence of drugs resistance to fungal strains, and treatment failures (25,26).…”

Epidemiology, Classification, Clinical Variations and Laboratory Diagnosis of Dermatophytes: A Narrative Review

“…A tinea corporis eruption that is more papulosquamous in presentation may be mistaken for psoriasis, lichen planus, seborrheic dermatitis, pityriasis rosea, or pityriasis rubra pilaris 10 . To avoid a misdiagnosis, identification of dermatophyte infections require prompt and methodical laboratory diagnosis [9][10][11] .…”
