''Histoplasma duboisii'' is a species of fungi within the Ajellomycetaceae family. Formerly known as ''Histoplasma capsulatum'' var. ''duboisii'',〔 Although the designation, "''Histoplasma capsulatum'' var. ''duboisii''," is still widely used in scientific literature, evidence for the name-change and elevation of H. duboisii to a species, comes from a genomic cladistics analysis, "Under a phylogenetic species concept based on possession of multiple shared derived characters, as well as concordance of four gene genealogies, H. capsulatum could be considered to harbor six species instead of three varieties." 〕 〔Further support for the name-change comes from quantitative analysis of the gene ''expression products''; "All the strains of H. capsulatum var. capsulatum RFLP classes II and III were grouped into two distinct clusters: the heterogenic RFLP class I formed a large, but also well-defined group, whereas the outgroup strains of H. capsulatum var. duboisii, B. dermatitidis, P. brasiliensis and S. schenckii were shifted away." 〕 it is the causative agent of African histoplasmosis. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Histoplasma duboisii」の詳細全文を読む スポンサード リンク
