Research Abstract |
Recently the number of patients affected by dermatophytosis are estimated more than 20% in Japan. For investigation on invasive (pathogenic) factor of dermatopytes, development of methods for destruction of target gene of the fungus is essential. In this study we constructed the original methods which are useful for investigation of invasive factor gene in major dermatophytes ; Trichophyton mentagrophytes using animal infectious models. At first we reported the new gene transformation system (Agrobacterium method) using Agrobacterium tumefaciens. Next we construct G418 as the marker of the multiple genes transformation. Finally we developed the Tmku80-destroyed Trichophyton, #49 strain. This strain has destroyed gene Tmku80 which is homolog of ku80 gene of T. mentagrophytes TIMM2789. By making #49 strain, specific gene destruction became possible, and also we could select target gene freely. At the same time we could compare the pathogenesis between modified gene strain and wild type strain of Trichophyton using experimental animal infectious models. Continuously we developed and reported a gene diagnosis system which is useful for human dermatophytosis. The result of this study would contribute to the analysis of clinical condition of dermatophytosis and progress of protection, diagnosis and therapy of the infection.
