Resumen:
Yeast strains obtained from blood cultures and catheters from intensive care units (ICU)
and hospitalised oncology paediatrics were studied. Yeast were the first cause of catheter
colonisation (51/627), and the third cause of bloodstream infection (44/6065). In
catheter, the most frequent species were Candida albicans (34%), C. parapsilosis (27.7%)
and C. tropicalis (15%). In blood, C. albicans (40.8%), C. parapsilosis (26.6%), C. tropicalis
(15%). Malassezia furfur and Malassezia sympodialis were isolated from catheters from
ICU patients. All isolates were susceptible to amphotericin B, 88.8% to itraconazole
and 91.9% to fluconazole. Candida albicans and C. tropicalis strains resistant to fluconazole
and itraconazol were detected. These results reveal a change in the predominant role of
C. albicans as cause of candidemia in hospitalised children and the emergence of
antifungal resistant species. These variations emphasise the importance of performing a
permanent surveillance to observe and assess them.
