laser irradiation on growth of trichophyton rubrum: an in vitro study
نویسندگان
چکیده
introduction: trichophyton rubrum is one of the most common species of dermatophytes which affects superficial keratinous tissue. it is not especially virulent but it can be responsible for considerable morbidity. although there are different therapeutic modalities to treat fungal infections, clinicians are searching for alternative treatment because of the various side effects of the present therapeutic methods. as a new procedure, laser therapy has brought on many advantages in clinical management of dermatophytes. possible inhibitory potential of laser irradiation on fungal colonies was investigated invitro in this study. methods: a total of 240 fungal plates of standard size of trichophyton rubrum colonies that had been cultured from the lesions of different patients at the mycology laboratory, were selected. each fungal plate was assigned as control or experimental group. experimental plates were irradiated by a laser system (low power laser or different wavelength of high power laser). the effects of different laser wavelengths and energies on isolated colonies were assessed. after laser irradiation, final size of colonies was measured on the first, the 7 th and the 14 th day after laser irradiation. results: although low power laser irradiation did not have any inhibitory effect on fungal growth, the q-switched neodymium-doped yttrium aluminium garnet (nd:yag) laser 532nm at 8j/cm 2 , q-switched nd:yag laser 1064nm at 4j/cm 2 to 8j/cm 2 and pulsed dye laser 595nm at 8j/cm 2 to 14j/cm 2 significantly inhibited growth of trichophyton rubrum in vitro. conclusion: q-switched nd:yag 532nm at 8j/cm 2 , q-switched nd:yag laser 1064nm at 4j/cm 2 to 8j/cm 2 and pulsed dye laser (pdl) 595nm at 8j/cm 2 to 14j/cm 2 can be effective to suppress trichophyton rubrum growth.

متن کاملAn ultrastructural study of Trichophyton rubrum induced onychomycosis
BACKGROUND Trichophyton rubrum (T.rubrum) caused onychomycosis is the most common nail fungal disease. The common diagnostic methods are direct microscopic examination and fungal culture. In this study we used scanning electron microscopy (SEM) and transmission electron microscopy (TEM) to study the subungual ultrastructural changes in T. rubrum induced onychomycosis. METHODS Six outpatients ...
متن کاملIn vitro Antifungal Activity of Limonene against Trichophyton rubrum
In this study, the antifungal activities of limonene against Trichophyton rubrum were evaluated via broth microdilution and vapor contact assays. In both assays, limonene was shown to exert a potent antifungal effect against T. rubrum. The volatile vapor of limonene at concentrations above 1 µl/800 ml air space strongly inhibited the growth of T. rubrum. The MIC value was 0.5% v/v in the broth ...

Scales from lesional skin of 12 patients with tinea pedis were investigated by scanning electron microscopy (SEM) and transmission electron microscopy (TEM) to gain an insight into the spatial and morphological changes of dermatophytes after application of a clinical dosage of topical luliconazole 1% cream (Lulicon® cream 1%). In all cases, Trichophyton rubrum was identified. The scales from th...
