[Clinical and molecular characterization of ESBL-producing enterobacteria isolated from bacteremia in a university hospital].

Introduction: Extended-spectrum-β-lactamases (ESBL) are plasmid-encoded enzymes that confer resistance to multiple antimicrobials. ESBL-producing enterobacteria that cause bacteremia limit therapeutic options and increase mortality.

Objective: To perform a clinical and molecular description of bacteremia caused by ESBL-producing enterobacteria.

[Epidemiologial profile of invasive candidiasis in intensive care units at a university hospital].

Unlabelled: Invasive candidiasis (IC) epidemiology has changed in critically ill patients and limited data are available in Chile.

Objective: To describe the epidemiological and microbiological profile of IC in critically ill patients.

Methods: Observational prospective study conducted from October 2001 to August 2003 in critically ill adults with suspected or confirmed IC.

[Evaluation of Hucker stain as Campylobacter sp screening detection during an acute diarrhea disease].

Campylobacter infection is one of the most frequent causes of gastroenteritis in the world and the third in Chile according to some studies. The routinary culture for Campylobacter in our country is not performed because of its high cost, and it is known, that the Hucker stain is a reasonable screening alternative. The objective of this study was to know the utility of the Hucker stain and estimate the frequency of Campylobacter in stool samples.
