a simple and rapid method to differentiate arthroderma benhamiae from microsporum canis.arthroderma benhamiae is increasingly isolated in central europe. in culture, this dermatophyte is difficult to differentiate macroscopically from microsporum canis, which is microscopically also true for weak or non-sporulating strains. although there are valid molecular methods for differentiating between these two dermatophytes, in everyday practice it would be helpful for epidemiological and treatment considerations to have a simple and rapid method available for discrimination.201323194462
disseminated dermatophytic pseudomycetoma caused by microsporum species.dermatophyte infection is almost exclusively a superficial cutaneous mycosis usually confined to the stratum corneum of nails and hairs of normal hosts. deep cutaneous and subcutaneous infections due to dermatophytes are exceedingly rare and usually limited to immunosuppressed individuals. these infections remain chronic and persist in spite of treatment.201223171014
feline polymorphonuclear neutrophils produce pro-inflammatory cytokines following exposure to microsporum canis.the mechanisms involved in the establishment of the specific immune response against dermatophytes remain unknown. polymorphonuclear neutrophils (pmns) are recruited early during the infection process and participate in the elimination of dermatophytes. they could therefore be involved in the induction of the immune response during dermatophytoses by producing specific cytokines. the aim of this work was to assess the in vitro cytokine production by feline pmns exposed to living arthroconidia fr ...201323141297

selection and validation of reference genes for qrt-pcr analysis of gene expression in microsporum canis growing under different adhesion-inducing conditions.dermatophytes are the group of filamentous fungi infecting keratinized structures such as skin, hair, and nails. knowledge about genes and molecular mechanisms responsible for pathogenicity, as well as other biological properties of microsporum canis is still relatively poor. the qrt-pcr is a reliable technique for quantifying gene expression across various biological processes, and choosing a set of suitable reference genes to normalize the expression data is a crucial step of this technique. w ...201829352152
resistance mechanism in a terbinafine-resistant strain of microsporum canis.to clarify the terbinafine (trf) resistance mechanism in a trf-resistant strain of microsporum canis, the expression of the pleiotropic drug resistance (pdr1), multidrug resistance (mdr1), mdr2 and mdr4 genes were investigated by real-time quantitative pcr (rt-qpcr) analysis, given the known interaction of the corresponding proteins with antifungals and with the efflux blocker fk506. the expression of the pdr1, mdr1, mdr2 and mdr4 genes was 2-4 times higher in the trf-resistant strain grown in t ...201829340910

in vitroantifungal activity of hexahydropyrimidine derivatives against the causative agents of dermatomycosis.nitrogenated heterocyclic compounds are present in both natural and synthetic drugs, and hexahydropyrimidine derivatives may prove to be efficient in treating dermatomycosis causing fungi. this study evaluated the antifungal activity of four hexahydropyrimidine derivatives against the dermatomycosis causing fungi. these derivatives were synthesized, characterized, and assessed in terms of their activity againsttrichophyton mentagrophytes,microsporum canis,microsporum gypseum,trichophyton rubrum, ...201729226215
antifungal activity of silver nanoparticles on fluconazole resistant dermatophytes identified by (gaca)4 and isolated from primary school children suffering from tinea capitis in ismailia - egypt.fungal infections caused by dermatophytes recently became more common. available antifungal drugs are limited because of emergence of resistant strains due to prophylaxis with them, so there is an urgent need for novel antifungals. this study is aimed to detect the antifungal activity of silver nanoparticles (snps) on fluconazole resistant dermatophytes isolated from primary school children clinically suffering from tinea capitis and attending el-sheikh zaid dermatology center in ismailia. the s ...201729208175
comparison of real-time pcr with fungal culture for the diagnosis of microsporum canis dermatophytosis in shelter cats: a field study.objectives fungal culture requires at least 14 days for a final result, compared with 1-3 days for pcr. the study compared a commercial real-time dermatophyte pcr panel with fungal culture in cats in a shelter setting for: (1) diagnosis of microsporum canis infection; and (2) determination of mycological cure. methods this was a cross-sectional, observational study of cats with suspicious skin lesions or suspected exposure to dermatophytosis. hair samples were collected for fungal culture and pc ...201829172910
genus- and species-level identification of dermatophyte fungi by surface-enhanced raman spectroscopy.this paper demonstrates that surface-enhanced raman spectroscopy (sers) coupled with principal component analysis (pca) can serve as a fast and reliable technique for detection and identification of dermatophyte fungi at both genus and species level. dermatophyte infections are the most common mycotic diseases worldwide, affecting a quarter of the human population. currently, there is no optimal method for detection and identification of fungal diseases, as each has certain limitations. here, fo ...201829156315
tinea folliculorum complicating tinea of the glabrous skin: an important yet neglected entity.dermatophytes are capable of infecting the skin and its appendages such as nails and hairs producing a variety of clinical conditions. hair invasion by dermatophytes is a key feature of tinea capitis and tinea barbae but not of tinea of glabrous skin. in this project, we studied the clinico-mycological aspects of follicular involvement in patients with dermatophytosis of the glabrous skin. in total, 16 patients, eight males and eight females, were included in the study. all were adults except fo ...201729087496
efficacy of itraconazole oral solution using an alternating-week pulse therapy regimen for treatment of cats with experimental microsporum canis infection.objectives the objective of this study was to evaluate itraconazole 10 mg/ml oral solution for the treatment of microsporum canis infection using an alternating-week pulse therapy regimen in a controlled laboratory setting. methods eighty cats with experimentally induced infections were randomly assigned to treatment (itraconazole vs control [sterile water]), administered 5 mg/kg orally once daily for 1 week on alternate weeks for 5 weeks, followed by a 4 week follow-up period. topical therapeut ...201729025320
proteolytic activity and cooperative hemolytic effect of dermatophytes with different species of bacteria.globally, dermatophytes are the most common filamentous group of fungi causing cutaneous mycoses. dermatophytes were shown to secrete a multitude of enzymes that play a role in their pathogenesis. there is limited data on co-hemolytic (camp-like) effect of different bacterial species on dermatophyte species. in this study, we sought to the evaluate exoenzyme activity and co-hemolytic effect of four bacteria on clinical dermatophytes isolated from patients in shiraz, iran.201628959790
evaluation of incubation time for microsporum canis dermatophyte cultures.objectives the goal of this study was to determine how frequently microsporum canis was isolated after 1, 2 and 3 weeks of incubation on dermatophyte culture medium either from untreated cats or cats during treatment. methods this was an observational retrospective study. toothbrush fungal culture results were examined from two data pools: untreated cats with suspect skin lesions and weekly fungal cultures from cats being treated for dermatophytosis. results results from 13,772 fungal cultures w ...201728920535
