[Microorganisms isolated from outpatient urine samples and antimicrobial susceptibility over a 12-year period]. / Microorganismos aislados de muestras de orina procedentes de la comunidad y patron de sensibilidad en un periodo de 12 anos.

This study aimed to determine the prevalence of microorganisms isolated from urine samples from outpatients and the resistance of the pathogens isolated to antimicrobial agents used in the province of Cordoba, Spain, which has a Health Area of approximately 776,000 inhabitants. It was a retrospective descriptive study covering a 12-year period (1992-2003). All samples were sent from primary care to the microbiology laboratory. The laboratory techniques and criteria for evaluation were the same in all cases. Escherichia coli was the most frequently isolated of the Gram-negative bacteria (64%), while Enterococcus faecalis was the most frequently isolated of the Gram-positive bacteria (6.9%). A decrease in susceptibility of the isolates to the most empirically used antimicrobial drugs was observed.

El objetivo de este estudio fue conocer la prevalencia de los microorganismos aislados de muestras de orina procedentes de la comunidaden la provincia de Córdoba (un área sanitaria de 776.000 habitantes aproximadamente), y además determinar las tasas de resistencia a losdiferentes antimicrobianos empleados en Atención Primaria. Se trata de un estudio descriptivo retrospectivo que abarca un periodo de 12años (1992-2003). Todas las muestras fueron remitidas desde los Centros de Salud al Laboratorio de Microbiología del Hospital UniversitarioReina Sofía. Todos los procedimientos analíticos se realizaron siguiendo el proceder habitual del laboratorio. Escherichia coli fue el microorganismoque se aisló con mayor frecuencia entre los gramnegativos, con una media en los doce años del 64%, y Enterococcus faecalis fueel que se aisló con mayor frecuencia entre los grampositivos, con una media del 6,9% del total de microorganismos. Observamos una disminuciónen la sensibilidad de los aislamientos a los antimicrobianos de mayor uso empírico
