Urinary tract infections are considered a health problem at hospital and community level due to the increase of antibiotic resistant bacteria. Objective: To analyze the pattern of susceptibility and antimicrobial resistance of Enterobacteriaceae causing urinary tract infection. Methods: A descriptive research of documentary design was applied. The population was 672 records of positive urine cultures, collected from the San Pablo Laboratory database in the period 2021-2022. For tabulation and analysis, the data obtained were processed in SPSS software version 25.0. Results: UTIs occur more frequently in females 86.5%. The age group with the highest incidence was adulthood 50.4%. The etiological agent with the highest incidence was Escherichia coli 75.74%, Citrobacter Freundii 8.93%, Klebsiella spp 6.10%. The production of BLEE as a mechanism of resistance predominated in the strains of E.coli and Klebsiella spp. A higher percentage of resistance was found for Ampicillin and SXT. The antibiotics with the best sensitivity were nitrofurantoin and fosfomycin. Conclusion: The species with the highest isolation, implicated in the etiology of urinary tract infections, continues to be E.coli with a high sensitivity to nitrofurantoin and fosfomycin.
