Abstract

CACERES ROJAS, Rolando et al. Sensitivity profile of Escherichia coli isolated from urinary tract infections of patients of the Regional Hospital of Villarrica from July 2013 to August 2015. An. Fac. Cienc. Méd. (Asunción) [online]. 2019, vol.52, n.2, pp.17-22. ISSN 1816-8949.  https://doi.org/10.18004/anales/2019.052(02)17-022.

Introduction:

The inappropriate use of antimicrobials is leading to a decrease in the antimicrobial sensitivity of microorganisms that cause infectious diseases. The clinical use of antimicrobials has been parallel to the emergence of bacteria resistant to its action.

Materials and methods:

The sensitivity profile of Escherichia coli isolated from patients with urinary tract infections (UTI) concurrent to the Regional Hospital of Villarrica in the period from 2013 to 2015 was determined.

Results:

Ampicillin showed a resistance of 100%, ciprofloxacin showed a sensitivity of 73%. Amikacin showed a sensitivity of 100% and gentamicin 82%. The family of carbapenem showed a sensitivity of 100%. Within the group of nitrofurans a sensitivity of 96% was found. Trimethoprim / sulfamethoxazole had a sensitivity of 57%. The presence of Extended Spectrum Beta Lactamase (ESBL) was determined in 13% of the strains of Escherichia coli studied.

Conclusions:

Gentamicin, nitrofurantoin and carbapenem have a high sensitivity, so in the presence of strains with ESBL they would be feasible options always accompanied by the evaluation of the renal profile and classifying the UTI as complicated or not.
