Epidemiology and molecular identification of mixed yeast isolates in Malaysia- A way forward
Invasive candidiasis is one of the most common systemicmycoses, and studies have shown mixed yeast infections. Malaysia lacks mixed yeastculture data.
Yeast isolates were collected in Sultan Abdul Halim Hospital,North Malaysia, from October 2020 to October 2021. Chromogenic Candida differentialagar media and PCR-RFLP were used to identify yeast species.
A total of 206 yeast isolates were collected from different body sites of patients.The majority of the yeast isolates (n=104) were obtained from the urine. Other isolates were extracted from blood (n=52), vaginal swabs (n=45), ear discharge (n=2), tracheal aspirate (n=2), tissue (n=2), skin (n=1), nail (n=1), sputum (n=1), and cerebrospinal fluid (n=1). In total, 200 yeast samples were identified as single species, and six isolates were a mixture of Candida species.
Malaysia lacks accurate epidemiological data on mixed yeast infections.We identified all samples to the species level, including mixed yeast cultures, using theMspI enzyme and PCR-RFLP.
