Background

Rhodotorula species were traditionally considered non-virulent environmental microorganisms, but are nowadays considered important human pathogens, especially in immunocompromised individuals.

Case report

We present the case of a 73 year-old man with diarrhea, anorexia and fever. In the blood analyses, both aerobic blood culture bottles yielded the growth of Rhodotorula dairenensis. The MALDI-TOF MS score was inadequate to provide an identification, which was achieved by means of molecular techniques. Treatment with an echinocandin was started, but the patient died.

Conclusions

Basidiomycetous yeast genera such as Rhodotorula can cause invasive and severe infections, e.g., fungemia, especially in patients with central venous catheter or another indwelling device.

癌症患者中的大仁红酵母菌血症。

背景

红酵母物种传统上被认为是无毒的环​​境微生物，但现在被认为是重要的人类病原体，尤其是在免疫功能低下的个体中。

案例报告

我们介绍了一名患有腹泻、厌食和发烧的 73 岁男性的案例。在血液分析中，两个需氧血培养瓶都产生了大仁红酵母菌的生长。MALDI-TOF MS 分数不足以提供鉴定，这是通过分子技术实现的。开始用棘白菌素治疗，但患者死亡。

结论

担子菌属酵母菌（如红酵母菌）可引起侵袭性和严重感染，例如真菌血症，尤其是在有中心静脉导管或其他留置装置的患者中。
