Screening of Candida dubliniensis from respiratory samples in Korea

초록

Background: Candida dubliniensis is newly described yeast that is a close phylogenetic relative of C. albicans and isolates mainly from the oral cavity. Objective: The aim of the present study was to screen for C. dubliniensis using the 'spiking' appearance on a blood agar plate (BAP), germ tube test with human pooled serum (HPS) and fetal bovine serum (FBS) and to investigate the prevalence of C. dubliniensis from respiratory samples in Korea. Methods: A total 434 isolates of Candida spp. were examined for the presence of 'spiking' on BAP and the germ tube test with HPS and FBS. Also all isolates were tested using the VITEK 2 ID-YST system. Results: No C. dubliniensis was found in the study population. C. albicans was the most frequently isolated species (74.9%). Conclusions: No C. dubliniensis was identified in our study. Further large-scale studies are needed to isolate and to confirm the prevalence of C. dubliniensis.
