【 摘 要 】

All the newborns with umbilical venous catheters, hospitalized in the neonatal intensive care unit at Januário Cicco Maternity Hospital in Natal, Brazil, between January, 2003 and December, 2004 were studied. The prevalence of Candida species in the tips of intra-venous catheters was assessed, as well as the coexisting exposures that the patients were subjected to. Catheter tips were cultivated in blood agar and when yeast culture occurred, the colony was subcultivated for species identification through morphologic and biochemical assays. From a total of 240 catheters, 41 were positive for yeasts, and 34 were submitted to identification. The following agents were isolated: 13 C. albicans (38%), 10 Candida parapsilosis (29%), 8 C. tropicalis (20%), one C. guilliermondii (3%), one C. famata (3%) and one Trichosporon spp. (3%). Three patients among those with positive catheter tip fungal cultures were also hemoculture positive, with the same fungal species at both sites. Among the coexisting exposures, it should be pointed out that all the patients underwent broad spectrum antibiotic therapy, used a nasogastric probe, in addition to undergoing other invasive procedures such as mechanical ventilation and umbilical catheter implantation.
