Resumen

Objetive: To determine the antibiotic resistance of Echerichia coli, in urine cultures, according to ESBL production, in hospitalized patients. The study: Descriptive-retrospective design. Bacterial identification was done with VITEK XL, susceptibility, with the CLSI M100 guidelines. 30 edition. Findings: E. coli ESBL positive, presented 0% resistance to: Meropenem, ertapenem, tigecycline and colistin. Piperacillin/tazobactam, nitrofurantoin, imipenem, amikacin with 16.7%, 6.2%, 5% and 1% respectively. E. Coli ESBL negative, presented 0% resistance to: cefotaxime, cefuroxime, tige cycline and piperacillin/tazobactam. Ceftriaxone, cefepime, gentamicin, cefazolin, ceftazidime, nitrofurantoin, meropenem, amikacin, imipenem, and ertapenem with 14.7%, 13%, 13%, 10.7%, 9.7%, 9.1%, 9.1%, 8%, 5%, 2.7%, respectively. Conclusion: Mer open en, ertapenem, tige cycline, cholesterol, piperacillin/tazobactam, nitrofurantoin, amikacin and imipenem, with less than 20% resistance, were the same for ESBL-positive E. coli, and E. coli, without considering ESBL production. © The Author(s) 2022.
