在对菲律宾棉兰老岛卡加延德奥罗（Cagayan de Oro）花中分离的酵母进行的分类研究中，菌株被确定为代表微卡atiella microsticta， Metschnikowia koreensis和迄今未描述的二态种。LSU 26S rRNA基因的D1/D2结构域、内部转录间隔区（ITS）和SSU 18S rRNA基因的序列在最后一组菌株中是相同的，与最近亲缘种双假丝酵母（Candida duobushaemulonii）型菌株的相应序列差异分别为4% （D1/D2）、7% （ITS）和1% （SSU）。在一项独立研究中，在马来西亚从一名死于吸入性肺炎的患者的血液中分离出一种D1/D2和ITS序列与菲律宾菌株非常相似的菌株。两组分离株均对阿尼杜冯宁、卡泊冯宁、氟康唑、伊曲康唑和伏立康唑中度敏感，但对两性霉素b耐药。序列分子系统发育分析表明，菲律宾和马来西亚分离株接近假丝酵母菌属假丝酵母菌复合体。为了反映样品采集地点的地理位置，我们提出了新的种名vulturna pro tempore sp. 11 .来容纳这些菌株。该型菌株为11-1170(T) (=CBS 14366(T) =CCY 094-001-001(T) = ncam - y02177 (T))，分离自菲律宾卡加延德奥罗。分枝库：mb817222。
In a taxonomic study of yeasts isolated from flowers in Cagayan de Oro, Mindenao Island, The Philippines, strains were identified as representing Kabatiella microsticta, Metschnikowia koreensis and a hitherto undescribed dimorphic species. Sequences of the D1/D2 domains of the LSU 26S rRNA genes, the internal transcribed spacer (ITS) regions and the SSU 18S rRNA genes were identical in the strains of the last-named group and differed from the corresponding sequences of the type strain of the closest related species, Candida duobushaemulonii, by 4% (D1/D2), 7% (ITS) and 1% (SSU). In an independent study, a strain with D1/D2 and ITS sequences very similar to those of the Philippine strains was isolated in Malaysia from the blood of a patient dying of aspiration pneumonia. Both groups of isolates were moderately sensitive to anidulafungin, caspofungin, fluconazole, itraconazole and voriconazole but resistant to amphotericin B. Molecular phylogenetic analysis of the sequences placed the Philippine and Malaysian isolates close to the Candida haemulonis complex of Candida species. To reflect the geographical location of the sites of sample collection, the novel species name Candida vulturna pro tempore sp. nov. is proposed to accommodate these strains. The type strain is 11-1170(T) (=CBS 14366(T) =CCY 094-001-001(T) =NCAIM-Y02177(T)) isolated in Cagayan de Oro, The Philippines. Mycobank: MB 817222.
