To study the current state and development in the sensitivity of Escherichia coli during 12 years, in order to find the use of 6 antimicrobials. A descriptive study of the annual sensitivity percentages of E. coli strains isolated from clinical samples between 1984 and 1995. Microbiology Laboratories in 15 County Hospitals in the province of Barcelona. E. coli strains, isolated from clinically significant samples, were studied for sensitivity against antimicrobials. Cefuroxime and Gentamicin had in vitro sensibility above 94%. Current sensitivity of E. coli to Norfloxacin was 85%. Amoxicillin-Clavulanic acid maintained its sensitivity at about 80% with few variations. Ampicillin and Co-trimoxazole had steady sensitivity figures, always below 50 and 70%, respectively. Progressive decrease in the sensitivity of E. coli strains to Norfloxacin was observed. There was excellent sensitivity to Cefuroxime and Gentamicin.
