All 11 patients with urinary tract infections survived, irrespective of the MIC. For other sources, 30-day mortality was lower for isolates with a MIC of ≤ 2 mg/liter than for isolates with a higher MIC (0% versus 41.1%; P = 0.02). %K Antibacterianos %K Estudios de cohortes %K Quimioterapia combinada %K Infecciones por escherichia coli %K Pruebas de sensibilidad microbiana %K Ácido senicilánico %K Infecciones urinarias %~
