Among the many fungal species described in the literature, yeasts of the genus Candida are the nosocomial infection agents of greater importance in the Intensive Care Unit (ICU), representing a challenge to the survival of patients with severe underlying diseases, due to susceptibility of these patients to fungal invasion. The phenotypic identification of yeast as well as periodic surveys can reveal important trends or even the appearance of new species, supporting the development of more assertive preventive measures. The objectives of this study were perform an epidemiological survey of yeasts found in catheter tip and blood cultures from patients of an oncology ICU and compare the isolated species, checking out differences of frequency in the isolation place. This is an analytical-descriptive retrospective observational study conducted in the ICU of a cancer institute, from January 2010 to December 2013 from the Microbiology Laboratory Database and Hospital Infection Control Commission (CCIH), electronically collected and processed for statistical analysis to assess correlation of species by SPSS 20.0 program and measure trends. The results were, for Catheter tips, 40 were positive, 15 for C. albicans (37.5%), 13 to C. parapsilosis (32.5%), 05 to C. tropicalis (12.5%) and 07 for other yeasts (17.5%). Blood cultures, 58 were positive, being 18 for C. albicans (31.0%), 17 C. tropicalis (29.3%), 10 for C. parapsilosis (17.2%), 05 for C. krusei (8.6%) and 08 for other yeasts (13.9%). Differences have been found in the frequency of the species in relation to studied topography.
