Eight strains with identical sequences of the D1/D2 domains of the large subunit rRNA genes were isolated from fallen fruits in two distant localities in Laos. These strains represent a novel dimorphic budding yeast species producing invasive pseudohyphae and a brown pigment when growing on media containing quinic acid as the sole carbon source or tryptophan as the sole nitrogen source. Phylogenetic analysis of the sequences of the D1/D2 domains, the internal transcribed spacer (ITS) regions and the 18S rRNA genes placed the novel species in the Metschnikowia clade close to Candida torresii, Metschnikowia drosophilae and Candida danieliae. The taxonomic name Metschnikowia laotica f.a., sp. nov., reflecting the geographical origin of the isolates, is proposed for the novel species. The type strain is 11-524(T) ( = CBS 12961(T) = NCAIM Y.02124(T) = CCY 64-4-1(T)). The Mycobank number is MB 807383.
从老挝两个不同地点的落地果实中分离到了 8 株具有相同大亚基 rRNA 基因 D1/D2 结构域序列的菌株。这些菌株代表了一种新型的二态出芽酵母物种，当在含有奎尼酸作为唯一碳源或色氨酸作为唯一氮源的培养基上生长时，它们会产生侵袭性假菌丝和棕色色素。对 D1/D2 结构域、内部转录间隔区 (ITS) 区域和 18S rRNA 基因序列的系统发育分析将新型物种置于 Metschnikowia 分支中，靠近 Candida torresii、Metschnikowia drosophilae 和 Candida danieliae。为了反映分离物的地理起源，提议将新型物种命名为 Metschnikowia laotica f.a., sp. nov.。模式菌株是 11-524(T)（=CBS 12961(T)=NCAIM Y.02124(T)=CCY 64-4-1(T)）。Mycobank 编号为 MB 807383。
