BACKGROUND Tinea capitis (TC) is a common dermatophyte infection of the scalp that can also involve the eyebrows and eyelashes. AIM This study aimed to find the causative fungus responsible for TC in Botswana and determine its association with the clinical types of TC. METHODS Samples for potassium hydroxide 10% mounts and fungal cultures were collected in a microbiology laboratory at the N...

BACKGROUND Onychomycosis accounts for up to 50% of all nail disorders. They can be caused by: yeasts, dermatophytes and non-dermatophyte moulds. OBJECTIVES AND METHODS A multicentre study designed to determine the prevalence, mycological test results, aetiological agents, and clinical presentation of onychomycosis was carried out. All fingernail and toenail samples taken during a one year per...

Distribution and prevalence of various species of dermatophytes are not the same in different areas of the world. The aim of the present study was epidemiologic evaluation of dermatophytic infections in our area. A retrospective epidemiologic study was carried out and all patients with dermatophyte positive smears identified at the Referral Center of Southwest Iran located in the city of Ahvaz ...

The intergenic spacer (IGS) of the rRNA genes was analyzed from the dermatophyte Trichophyton violaceum isolated from cases of tinea capitis in Taiwan and Iran. T. violaceum strains were cultured from different colonies, from single conidial colonies derived by dilution plating, and from micromanipulation of single conidia from clinical samples. A ribosomal DNA probe hybridizing to multiple Eco...

Dermatophytosis is caused by a dermatophyte fungus that affects the stratum corneum and keratinized tissue. Dermatophyte fungus has been reported worldwide as the causative agent of dermatophytosis, but the etio-epidemiological aspects of these mycoses in the state of Pará remain unknown. The purpose of this study was to describe the etio-epidemiological profile of dermatophytosis diagnosed in ...

AIM To determine the incidence and etiological agents of dermatophytosis of male genitalia in Sarajevo area, Bosnia and Herzegovina, during a 5-year period (2009-2013). METHODS A total of 313 male patients with confirmed dermatophyte infection elsewhere in the body was analyzed. All samples (skin scrapings and hairs) were treated with lactophenol to detect a possible presence of fungal elemen...

PURPOSE To evaluate in-office dermatophyte test medium (DTM) culture as an alternative to traditional laboratory fungal culture for confirming a diagnosis of onychomycosis, and to determine the prevalence of dermatophytes as a cause of onychomycosis in patients not participating in a clinical trial. DESIGN This nationwide multicenter prospective study enrolled 1100 adult patients with suspect...

By means of UV radiation 74 physiological mutants of the dermatophyte Trichophyton mentagrophytes (Robin) Blanchard were induced. These mutants had changed optimum cultivation temperature and mostly changed morphology and sporulation as well.

The effect of 12 different experimental compositions of phosphate-bonded SiO2 investments was examined on cast pure titanium. The mold temperature was 600 degrees C and the casting was conducted with an argon-arc melting and pressure casting machine. Castability was evaluated by the volume of casting porosity, which was calculated from the volume of wax pattern (15 mm x 15 mm x 1.5 mm), the wei...
