Dermatophyte is a group of closely related fungi that have the capacity to invade keratinized tissue of humans and other animals. The infection known as dermatophytosis, caused by members of the genera Microsporum, Trichophyton, and Epidermophyton includes infection to the groin (tinea cruris), beard (tinea barbae), scalp (tinea capitis), feet (tinea pedis), glabrous skin (tinea corporis), nail...

OBJECTIVES Recently, bergamot oil was shown to be a potent antifungal agent in vitro against clinically important Candida species. In this study, the activities of bergamot natural essence and its furocoumarin-free and distilled extracts on dermatophytes such as Trichophyton, Microsporum and Epidermophyton species were investigated. METHODS In vitro susceptibility testing assays on 92 clinica...

Macroconidia of Microsporum gypseum release free amino acids into the medium during germination. A single alkaline protease is also found in the germination supernatant fraction. The purified protease is capable of hydrolyzing isolated spore coats in vitro. Phenyl methyl sulfonyl fluoride (PMSF) is an effective inhibitor of the protease. Incorporation of PMSF at 10(-4)m into the germination sys...

Six cultures of Microsporum amazonicum were recently isolated from the hair of six spiny rats (Proechimys guyannensis) trapped near the city of Belém, Brasil. When the six isolates were paired with each other in ali possible combinations on soil-hair plates, eight of 15 pairs developed fertile ascocarps. Based on the morphology of the gymnothecia, the perfect state was classified in the genus N...

A novel dermatophyte species is described in the Microsporum cookei clade. It differs significantly from known taxa in the two molecular markers analyzed, i.e., ITS and partial β-tubulin (BT2). Morphologically the species was characterized by smooth- or only slightly rough-walled conidia, but isolates rapidly became pleomorphic with sparse, smooth- and thick-walled macroconidia in addition to m...

A total of 68 soil samples was collected from "favelas" (slums), schools, public squares, beaches and vacant lots in the city of João Pessoa-PB, Brazil. A search for dermatophytes in these soils was carried out by using the Vanbreuseghem technique. As a result, 48 strains and 6 dermatophytes species were isolated. Trichophyton terrestre (25.0%), Microsporum gypseum (20.8%) and Anthroderma gypse...

a 3-month-old male red fox that was in contact with a persian cat referred to the small animal hospital, faculty of veterinary medicine, university of tehran with multi-focal circular non-pruritic skin lesions and hair loss mainly on the head and extremities. a complete series of dermatologic tests such as wood’s light examination, direct microscopic examination, and fungal culture were perform...

Dermatophyte and yeast species have been screened for their degradative ability towards various keratin substrates. Application of soluble preparation of keratin (KS) of chicken feathers enables a preliminary evaluation of the growth of the fungi and screening of fungal isolates that possesed keratinolytic activity and keratinase enzyme. Five dermatophytes i.e. Trichophyton rubrum, Trichophyton...
