イヌから分離されるマラセチアは Malassezia pachydermatis が主体であり,その関与が予想される “マラセチア皮膚炎” と呼ばれる疾患がある.皮疹は脂漏部位の鱗屑を伴う比較的境界明瞭な紅斑を特徴とし,慢性経過を辿ると苔癬化や色素沈着を認める.その臨床はヒトの脂漏性皮膚炎に相当している.今後,ヒトと動物に共通する疾患としてその相違点を明らかにすることで,この領域における普遍的病態の理解を深めることが可能と推察された.

A newly proposed taxonomy of Trichophyton mentagrophytes and related species was introduced and verified with the grounds for the new classification, phylogenetic analysis, and Templeton's cohesive species concept. So-called asexual species were shown to retain sexual ability and different host preferences were shown not to be comparable to different ecological niches. We showed that genealogical concordance phylogenetic species recognition (GCPSR) can be applied to so-called asexual Trichophyton species. The results of GCPSR analysis and mating experiments demonstrated that Arthroderma simii, A. vanbreuseghemii, T. mentagrophytes var. interdigitale, and T. tonsurans may be considered as single phylogenetic species, and that A. benhamiae, T. concentricum, T. verrucosum, and T. mentagrophytes var. erinacei may also be considered as single phylogenetic species. In addition, the conspecificity of three Arthroderma species may also be demonstrated in future. In conclusion, we should not hastily revise the nomenclature based on the phylogenetic tree from only one gene, because different genes can yield different phylogenetic trees. Therefore, we recommend retaining the previous taxonomy until an acceptable taxonomy is proposed.
