All the currently recognized Malassezia species have been isolated from mammals. However, only a few of them have been isolated from birds. In fact, birds have been less frequently studied as carriers of Malassezia yeasts than mammals.
In this study we describe two new taxa, Malassezia brasiliensis sp. nov. and Malassezia psittaci sp. nov.
The isolates studied in this publication were isolated from pet parrots from Brazil. They were characterized using the current morphological and physiological identification scheme. DNA sequencing and analysis of the D1/D2 regions of the 26S rRNA gene, the ITS-5.8S rRNA gene sequences and the β-tubulin gene were also performed.
The strains proposed as new species did not completely fit the phenotypic profiles of any the described species. The validation of these new species was supported by analysis of the genes studied. The multilocus sequence analysis of the three loci provides robust support to delineate these species.
These studies confirm the separation of these two new species from the other species of the genus Malassezia, as well as the presence of lipid-dependent Malassezia yeasts on parrots.
目前所有已被确认的马拉色菌属物种均从哺乳动物中分离得到。然而，其中只有少数是从鸟类中分离出来的。事实上，与哺乳动物相比，鸟类作为马拉色菌酵母携带者的研究较少。
在本研究中，我们描述了两个新分类单元，即巴西马拉色菌新种和鹦鹉马拉色菌新种。
本出版物中研究的分离株从巴西的宠物鹦鹉中分离得到。它们采用当前的形态学和生理学鉴定方案进行特征描述。还进行了26S rRNA基因的D1/D2区域、ITS-5.8S rRNA基因序列和β-微管蛋白基因的DNA测序及分析。
被提议为新物种的菌株不完全符合任何已描述物种的表型特征。对所研究基因的分析支持了这些新物种的验证。对三个基因座的多位点序列分析为界定这些物种提供了有力支持。
这些研究证实了这两个新物种与马拉色菌属的其他物种相分离，以及鹦鹉身上存在脂质依赖性马拉色菌酵母。
