Piperacillin/tazobactam, nitrofurantoin, imipenem, amikacin with 16.7%, 6.2%, 5% and 1% respectively. E. Coli ESBL negative, presented 0% resistance to: cefotaxime, cefuroxime, tigecycline 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: Meropenen, ertapenem, tigecycline, cholesterol, piperacillin/tazobac...

Introduccion: Bacterial resistance to antibiotics is associated with increased morbidity and mortality. Objective: Determine the antibiotic resistance of the most common bacteria isolated in blood cultures in a Neonatal Intensive Care Unit. Materials and methods: Descriptive – retrospective, the identification of bacteria was done with VITEK XL, the susceptibility was done with the CLSI M100 guidelines. 30 edition. Results: The antibiotic resistance of the isolated bacteria was: Imipenem 15.6%, Meropenem 14.3%, Piperacillin/tazobactam 9.4%, Vancomycin 8.5%, Colistin 7.7%, Quinupristin/dalfopristin 7.1%, Amicacin 6.7%, Linezolid 2.7%. Tigecycline, Nitrofurantoin, Ertapenem, Tobramycin, Chloramphenicol, Streptomycin, Gentamicin had 0% resistance. The ECN had resistance to vancomycin 7.9%, Quinupristin/dalfopristin (6.4%), Linezolid (2.8%). Tigecycline, Nitrofurantoin, Doxycycline and Chl...

Introducción. La resistencia antimicrobiana incrementa la morbimortalidad y es un problema serio en el mundo. Objetivo: Describir la resistencia antibiótica de bacterias aisladas en hemocultivos y Urocultivos en niños hospitalizados menores de 15 años. Material y Métodos: Estudio descriptivo – retrospectivo. La identificación bacteriana se hizo con VITEK XL, la susceptibilidad antibiótica con el CLSI. Resultados: Hemocultivos: Staphylococcus hominis 12,5% resistente a la Vancomicina. El Staphylococcus epidermidis, tuvo 100% de resistencia a Oxacilina y 0% resistencia a Vancomicina. Urocultivos: Klebsiella pneumoniae 0% resistencia a Amikacina, Gentamicina y Nitrofurantoina. La Escherichia Coli, tuvo resistencia para Amikacina 1,96%, Nitrofurantoina 3,92%. Conclusiones: E, Coli, resistencia menor de 6,25% para Amikacina y Nitrofurantoina. La Klebsiella pneumoniae, 0% de resistenc...

Introduction: Antimicrobial resistance increases morbidity and mortality and is a serious problem in the world. Objective: to describe the antibiotic resistance of bacteria isolated in blood and urine cultures in hospitalized children under 15 years of age. Material and Methods: Descriptive - retrospective study. Bacterial identification was made with VITEK XL, antibiotic susceptibility with CLSI. Results: Blood cultures: Staphylococcus hominis 12.5% ​​resistant to Vancomycin. Staphylococcus epidermidis had 100% resistance to Oxacillin and 0% resistance to Vancomycin. Urine cultures: Klebsiella pneumoniae 0% resistance to Amikacin, Gentamicin and Nitrofurantoin. Escherichia Coli, had resistance to Amikacin 1.96%, Nitrofurantoin 3.92%. Conclusions: E, Coli, resistance less than 6.25% for Amikacin and Nitrofurantoin. Klebsiella pneumoniae, 0% resistance for Amikacin and Gentamicin. Blo...
