Thirty-nine Arthroderma vanbreuseghemii isolates identified by mating behavior were assayed to determine their ribosomal RNA gene internal transcribed spacer (ITS) region genotypes. Twenty-two isolates of mating type (+) and 4 of (-) showed the genotype of Trichophyton mentagrophytes var. interdigitale, 9 isolates of mating type (+) and 4 of (-) showed the genotype of A. vanbreuseghemii. Nine o...

background: subtilisin -like proteases are the group of proteases including keratinases found in dermatophytes which de­graded keratin. determination of the proteases activity of trichophyton vanbreuseghemii isolates which were obtained from soil and clinical and soil isolates of microsporum gypseum in iran and characterization of their genome were aim of present study. methods: ezymatic activi...

We present a familial infection caused by Arthroderma vanbreuseghemii. The proband is a 4-year-old boy, who had played with rabbits at his rabbit-farm neighbor. He complained of pruritus and pain in his scalp, which displayed redness, alopecia and painful cysts and eventually discharged pus and scabbed. Several erythema on his face and abdomen were also presented. He was diagnosed as having imp...

Three genetically hybrid F1 progenies produced between a clinical isolate of Arthroderma simii (KMU4810) and a tester strain of A. vanbreuseghemii (RV27961) were crossed with two tester strains of A. vanbreuseghemii (RV27961 and RV27960) and a tester strain of A. benhamiae (RV30001), respectively. Three crossings yielded hybrid second progenies. Another interspecies crossing between A. simii (K...

Soil is well known to support the transient or ongoing existence of kerathophilic fungi and potential sources of infection for humans and animals. Fifty soil samples were collected from various areas of forests and farmyards at Golestan Province in the north part of Iran to determine the prevalence of keratinophilic fungi and dominant species. A total of 357 fungal colonies including 13 genera ...
