Method and apparatus for using computer controlled, fiber-coupled laser delivery of treatment specific wavelength, intensity and duration of UV irradiation to control bacterial, fungal, viral and mold infections in bodily cavities, fluids and external applications. The method of treatment is focused on DNA breakdown beyond repair by natural DNA repair mechanisms of the pathogen, with less than damaging doses to tissues being treated, thus avoiding mutagenicity and carcinogenicity. The minimal intensity and duration and exposure area of any given surface of tissue to be treated is to be pre-determined by tissue and pathogen testing to optimize the therapeutic ratio. External applications include specifically Trichophyton Rubrum (toenail fungus) through the nail and Pseudomonas Aeruginosa infections in burns and elsewhere.

Dermatophytes which belong to one of the three genera Epidermophyton, Trichophyton and Microsporum are the main cause of fungal infections of skin, hair and nails. Traditional diagnostic procedures consist of microscopy and culture, but due to the slow growth rate of dermatophytes typically two to four weeks are needed before a final diagnosis is obtained. The present invention is a rapid DNA extraction method extracting nucleic acids from fungi (e.g. dermatophytes and other pathogenic fungi) which can be performed from directly on hair, nail or skin specimens from humans, from naturally or experimentally infected animals or from cultured fungal colonies for the use in PCR amplification and detection assays. The present invention also includes specific primer sets for detection of any dermatophyte and for species specific detection of Trichophyton rubrum and Epidermophyton floccosum by PCR and a kit for diagnosing fungal infections.
