Las infecciones del tracto urinario ITU son frecuentes en la comunidad. En los aislamien-tos de E. Urinary tract infections UTI are common in the community.

However, information of resistant isolates in this context is limited in Latin America. A case-control study was conducted between August and December of in three Colombian tertiary-care institutions. All participating patients were asked for a urine sample.

ESBL confirmatory test, antibiotic susceptibility, and molecular epidemiology were performed in these E. Clinical and epidemiological information was recorded, and a statistical analysis was performed. Of the recruited patients, had a positive urine culture, of which grew E. The majority of ESBL isolates were susceptible to ertapenem, phosphomycin and amikacin. Most of these isolates had 8 out of the 9 analysed virulence factors.

Sin embargo, a pesar del incremento sostenido en el reporte de aislamientos de E.
