infection in the central catheter of a patient without sepsis symptoms.

Background: is an emerging yeast frequently reported as resistant to multiple antifungal drugs commonly used to treat infections. This specie can colonize the patient's skin and has great ability for producing outbreaks in hospitals. is phylogenetically related to other species, can be misidentified using conventional biochemical or commercial methods and requires specific technology for its identification.

Case Report: We report the first isolate of in Cali, Colombia, from a central venous catheter in a 37-year-old patient with rheumatoid arthritis and endocarditis who did not have symptoms of sepsis. The yeast was initially misidentified as using the Phoenix system and subsequently identified as by matrix-assisted laser desorption/ionization-time-of-flight mass spectrometry (MALDI-TOF MS). The broth microdilution method was used to determine the minimum inhibitory concentration; the isolate was susceptible to fluconazole, itraconazole, voriconazole and amphotericin B.

Conclusions: This report contributes to knowledge of the epidemiology of infections in individuals with underlying disease and describes an isolate with a behavior different from what is usually reported.
