Abstract

Here we describe the case reports of three patients, 35, 64, and 72 year old, respectively, who were presented to the dermatology clinic for suspected onychomycosis with discolored and hardened nails. Both light microscopic analysis of the samples taken and culture analysis on SDA and DTM media were carried out. Direct microscopic analysis revealed the presence of yeast cells in the interstitial space of keratinocytes. Culture examinations resulted in the isolation of yeasts of the genus Rhodotorula. Subsequent metabolic and morphological analysis was conducted to ascertain the identification of the genus and species as Rhodotorula mucilaginosa. The involvement of this opportunistic pathogen in cases of onychomycosis is considered very rare and usually regarded as incidental; however, it should not be ruled out as a possible cause in favor of the more common dermatophytes or Candida spp. infections.

粘液红霉菌（A. Jörg.）1928年哈里森和甲癣：三例报告为一个不寻常的和低估的组合。

在这里，我们描述的病例报告三名患者，35岁，64岁和72岁，谁提出了怀疑甲真菌病，指甲变色和硬化皮肤科诊所。对采集的样品进行光镜分析，并对SDA和DTM培养基进行培养分析。直接显微镜分析显示，在角质形成细胞的间隙中存在酵母细胞。培养试验分离出红酵母属酵母。随后进行了代谢和形态分析，确定该属和种为粘红曲菌。这种机会性病原体在甲癣病例中的参与被认为是非常罕见的，通常被认为是偶然的，然而，它不应该被排除为更常见的皮肤真菌或念珠菌感染的可能原因。

期刊介绍： FEMS Microbiology Letters gives priority to concise papers that merit rapid publication by virtue of their originality, general interest and contribution to new developments in microbiology. All aspects of microbiology, including virology, are covered. 2019 Impact Factor: 1.987, Journal Citation Reports (Source Clarivate, 2020) Ranking: 98/135 (Microbiology) The journal is divided into eight Sections: Physiology and Biochemistry (including genetics, molecular biology and ‘omic’ studies) Food Microbiology (from food production and biotechnology to spoilage and food borne pathogens) Biotechnology and Synthetic Biology Pathogens and Pathogenicity (including medical, veterinary, plant and insect pathogens – particularly those relating to food security – with the exception of viruses) Environmental Microbiology (including ecophysiology, ecogenomics and meta-omic studies) Virology (viruses infecting any organism, including Bacteria and Archaea) Taxonomy and Systematics (for publication of novel taxa, taxonomic reclassifications and reviews of a taxonomic nature) Professional Development (including education, training, CPD, research assessment frameworks, research and publication metrics, best-practice, careers and history of microbiology) If you are unsure which Section is most appropriate for your manuscript, for example in the case of transdisciplinary studies, we recommend that you contact the Editor-In-Chief by email prior to submission. Our scope includes any type of microorganism - all members of the Bacteria and the Archaea and microbial members of the Eukarya (yeasts, filamentous fungi, microbial algae, protozoa, oomycetes, myxomycetes, etc.) as well as all viruses.
