The effects of laser irradiation on Trichophyton rubrum growth

The effects of various laser wavelengths and fluences on the fungal isolate, Trichophyton rubrum , were examined in vitro. Standard-size isolates of T. rubrum were irradiated by using various laser systems. Colony areas were compared for growth inhibition on days 1, 3, and 6 after laser irradiation....

Description
Summary:The effects of various laser wavelengths and fluences on the fungal isolate, Trichophyton rubrum , were examined in vitro. Standard-size isolates of T. rubrum were irradiated by using various laser systems. Colony areas were compared for growth inhibition on days 1, 3, and 6 after laser irradiation. Statistically significant growth inhibition of T. rubrum was detected in colonies treated with the 1,064-nm Q-switched Nd:YAG laser at 4 and 8 J/cm 2 and 532-nm Q-switched Nd:YAG laser at 8 J/cm 2 . Q-switched Nd:YAG laser at 532- and 1,064-nm wavelengths produced significant inhibitory effect upon the fungal isolate T. rubrum in this in vitro study. However, more in vitro and in vivo studies are necessary to investigate if lasers would have a potential use in the treatment of fungal infections of skin and its adnexa.
