[Uncomplicated urinary tract infection in women: etiology and antimicrobial resistance].

Our objectives were to determine the etiology and analyze the antibiotic resistance profiles of microorganisms causing uncomplicated urinary tract infections in our setting. An analytical cross-sectional study was conducted. In vitro antimicrobial resistance of urine cultures was analyzed. 580 urine cultures of women over age fifteen were included. 82.6 % of urine cultures corresponded to cystitis and the remaining 17.4 % corresponded to pyelonephritis. 353 urine cultures of women <50 years old (60.9%) and 227 of women = 50 years old (39.1%) were obtained. The most common pathogens were Escherichia coli (85.5 %) and Klebsiella pneumoniae (4.7 %). For Escherichia coli, there was a resistance of 28.6% to trimethoprim-sulfamethoxazole,7.9% to ciprofloxacin and 0.4% to nitrofurantoin. Significant difference (p = 0.005) was seen in the resistance to ciprofloxacin in women = 50 years old. Our data show there is a low in vitro resistance to nitrofurantoin
