Concerning the presumptive identification of Candida kefyr on Uriselect™4 agar Gómez-Vicente, Esther Navarro-Marí, José María Rodríguez Guerrero, Enrique Rosales-Castillo, Antonio Gutiérrez Fernández, José Candida kefyr urinary tract infection chromogenic agar Introduction. 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. Material and 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. 2024-07-22T07:56:25Z 2024-07-22T07:56:25Z 2023-11-06 journal article E.
