摘要
目的：非白色念珠菌，如kefyr假丝酵母，是新出现的病原体。显色培养基对诊断尿路感染（UTIs）非常有用。目的是描述这种物种在非特异性显色培养基上的行为。方法：对2016年至2021年间在格拉纳达（西班牙）Virgen de las Nieves医院微生物实验室检测到的念珠菌尿病例进行回顾性研究（N=2130）。尿液样本定量接种在非选择性UriSelect上™4显色琼脂。结果：在2016年至2021年间，凯菲尔念珠菌是我们环境中导致念珠菌尿症的第七大常见念珠菌（n=15）。斑点状和蓝色的C.kefyr菌落的宏观外观允许直接鉴定这些微生物。结论：本研究首次描述了C.kefyr对UriSelect的特定行为™4琼脂，根据其酶特性将其与其他念珠菌物种区分开来。
Concerning the presumptive identification of Candida kefyr on Uriselect™4 agar.
Objective: Non-albicans Candida species, such as Candida kefyr, are emerging pathogens. Chromogenic media are highly useful for the diagnosis of urinary tract infections (UTIs). The aim was to describe the behavior of this specie on a non-specific chromogenic medium.
Methods: A retrospective study of cases of candiduria detected in the Microbiology laboratory of the Virgen de las Nieves Hospital in Granada (Spain) between 2016 and 2021 (N=2,130). Urine samples were quantitatively seeded on non-selective UriSelect™4 chromogenic agar.
Results: Between 2016 and 2021, C. kefyr was the seventh most frequent Candida species responsible for candiduria in our setting (n=15). The macroscopic appearance of C. kefyr colonies, punctiform and bluish, allowed the direct identification of these microorganisms.
Conclusions: This study provides the first description of the specific behavior of C. kefyr on UriSelect™4 agar, which differentiates it from other Candida species based on its enzymatic characteristics.
