Species of dermatophytes are classified into three anamorphic (asexual) genera, Epidermophyton, Microsporum, and Trichophyton. Conventional methods used to identify dermatophytes are often lengthy and may be inconclusive because of atypical microscopic or colony morphology. Based on the internal transcribed spacer 1 (ITS-1) and ITS-2 sequences of the rRNA genes, an oligonucleotide array was dev...

background and purpose: superficial mycotic infections have been only poorly described in koalas and there are no reliable mycologically confirmed data regarding clinical isolation of dermatophytes in this animal. we report an 11-yearold female koala, kept in a zoo in tokyo, japan, and presenting with hyperkeratotic lesions and scaly plaques on forepaw claws and pads reminiscent of fungal infec...

The ozone is effective against most microorganisms due to its high oxidant power. Low concentrations and short-term contact are sufficient to inactivate bacteria, mold, yeast, parasites, seaweeds, protozoa and fungi. Microsporum canis is an important agent of dermatophitosis in human and animal. The aim of the current study was to assess the efficacy of ozonized oil over Microsporum canis in ra...

BACKGROUND Dermatophytes are the main causative agent of all onychomycosis, but genus Microsporum is infrequent and the risk of acquiring the infection is often associated with exposure to risk factors. OBJECTIVES To describe clinical characteristics of onychomycosis due to Microsporum onychomycosis in an urban population. METHODS This was a retrospective analysis of the epidemiological and...

A rapid two-step DNA extraction method and a multiplex PCR for the detection of dermatophytes in general and Trichophyton rubrum specifically were developed and evaluated with DNA extracted from pure cultures and from clinically diseased nails. DNA from the following dermatophytes was used: Epidermophyton floccosum, Microsporum audouinii, Microsporum canis, Microsporum gypseum, Microsporum nanu...

Germination of Microsporum gypseum macroconidia was accompanied by the release of alkaline protease, calcium ions, and inorganic phosphate into the germination fluid. The rate of germination was greatest during the first 2 hr, decreasing thereafter. This decrease in rate was accompanied by a decrease in protease activity, which was caused by an interaction of the enzyme with the inorganic phosp...

BACKGROUND Dermatophytosis, and particularly the subtype tinea capitis, is common among African children; however, the risk factors associated with this condition are poorly understood. To describe the epidemiology of dermatophytosis in distinct eco-climatic zones, three cross-sectional surveys were conducted in public primary schools located in the Sahelian, Sudanian and Sudano-Guinean eco-cli...

The aim of the present study was to investigate anti fungal activities of the fresh extract of Allium ascalonicum Linn. (Liliaceae) against clinically important yeast, dermatophytes and some saprophytic fungi in vitro. The anti fungal effects of fresh crude juice of shallot were determined against 11 isolates of Candida albicans, three species of dermatophytes (Microsporum gypseum, Trichophyton...

This study evaluated the prevalence of Tinea capitis among schoolchildren at one primary school and also identified the causative agents. Scalp flakes were collected from children presenting clinical signs suggestive of Tinea capitis. Dermatophytes were identified by following standard mycological procedures. This study found a clinical prevalence of Tinea capitis of 9.6% (110/1149). The dermat...
