Among the fungi, dermatophytes are the major cause of spectrum of superficial mycoses medically known as dermatophytosis (tinea) in human and animal. Treatment of these infections has still remained difficult. The aim of this survey was to evaluate in vitro anti-dermatophytic activity of ethanolic extract (EtOH) from Satureja khuzestanica leaf (SKLE) against some clinically important dermatophyte species from the genera of Trichophyton, Microsporum and Epidermophyton. Minimal inhibition concentration (MIC) of SKLE was tested against 14 dermatophyte strains of 5 species by using agar dilution method...

BACKGROUND: Mycological culture is the traditional method for identifying infecting agents of onychomycosis despite high false-negative results, slower processing, and complications surrounding nondermatophyte mold (NDM) infections. Molecular polymerase chain reaction (PCR) methods are faster and suited for ascertaining NDM infections. METHODS: To measure agreement between culture and PCR methods for identification of infecting species of suspected onychomycosis, single toenail samples from 167 patients and repeated serial samples from 43 patients with suspected onychomycosis were processed by culture and PCR for identification of 16 dermatophytes and five NDMs...

Tinea capitis is the most common pediatric superficial dermatophyte infection. The causative species vary, as for instance, Microsporum canis predominates in Europe, while Trichophyton tonsurans predominates in North America. Tinea capitis does not respond well to topical therapy alone, thus oral therapy is requisite. The drug of choice is griseofulvin; however in some countries, it is no longer available. Fungal culture should be requested in the persistent, scalp lesion and trichoscopy can put forward a speedy diagnosis by its characteristic findings...

BACKGROUND: Microsporum gypseum is a geophilic dermatophyte that colonises keratinous substances in the soil. Fur-bearing animals carry this dermatophyte but are rarely infected. Human infection can be acquired from the soil, carrier or infected animals, and rarely other humans. M gypseum is an uncommon cause of cutaneous infection in humans and typically manifests as tinea corporis, tinea barbae, and tinea capitis. Onychomycosis is rarely caused by M gypseum. CASE SUMMARY: We present a case of a 32-year-old white man who presented with a red scaly rash and nail dystrophy after adopting a pet rat 10 years prior to presentation...

Environmental conditions for swimming facilities may support fungal growth and also may represent a biological risk for users. However, since previously published studies both cleaning procedures and sanitary regulations are likely to have been improved. The aim of the study was to examine whether attendance to public swimming pools was still a risk factor for fungal infection of the skin in Poland. We investigated the occurrence of mycotic species, in a sample from Polish swimming pools. Detection and identification of isolated species were achieved by cultural and morphological methods...
