La infección del tracto urinario (ITU) en un hospital universitario de Santafé de Bogotá: etiología y evaluación de los antimicrobianos

Abstract

This study was conducted in an attempt to document the etiology and antimicrobial susceptibility in urinary tract infection (UTI). Two hundred and forty five (245) specimens of urine (nosocomial and community acquired) from the San Ignacio University Hospital were studied. Urine specimens employing sediment, Gram smears, reactive strip, and bacteriological culture were studied. Also, and antimicrobial susceptibility test using the Kirbv- Bauer method was carried aout. From 245 urine soecimens. 45 were discarded, 200 were cultured; 100 were positive by culture. The most frequently isolated microorganisms were: E. coli (84%) and Proteus sp. (6%). The antibiotic susceptibility test showed the following results: cefotaxime (100%), norfloxacine (98%), netilmicine (98%), amikacine (98%), nitrofurantoine (92%), gentamicine (86%), nalidixic acid (78%), trimethoprimsulfamethozaxol (57%) and ampicilin (25%). The most effective antimicrobial agents for bacteria isolated in the UTI because of their low cost and high activity were: nitrofurantoine, norfloxacine, amikacine, netilmicine and gentamicine.
