[Antimicrobial resistance patterns of isolates from urine cultures at an oncological center].

Objective: To describe the patterns of antimicrobial resistance of organisms isolated from urine cultures at a teaching oncological hospital for adult patients.

Material And Methods: All strains obtained from urine cultures from 1998 to 2005 were included. Mean susceptibilities were obtained for each antimicrobial tested; nosocomial and community-acquired isolates were analyzed separately.

[Asymptomatic fungemia caused by Acremonium sp associated with colonization of a central venous catheter].

Background: Microorganisms considered saprophytes have emerged as invasive or indolent pathogens among immuno-compromised patients.

Material And Methods: We detected an initial case of catheter-related Acremonium sp fungemia on a previously asymptomatic patient. We diagnosed a second case five weeks later.

[Trend of antimicrobial drug-susceptibility of blood isolates at an oncological center (1998-2003)].

Objective: To describe the patterns of antimicrobial resistance organisms isolated in blood cultures from patients detected in a tertiary level of care, teaching oncological hospital.

Material And Methods: All strains obtained from blood cultures from 1998 to 2003 were included and processed using the Bactec and Microscan system to determinate isolates and susceptibility to antimicrobials. The percent difference (increase or decrease) was obtained by comparing the frequency of resistance at baseline and at the end of the study.
