“…To summarize the combined results from both mouse strains, mature adult mice were better able to control bacterial urine colonization than young or aged mice, resulting in reduced bladder and kidney colonization and a reduced incidence of bacteremia. These findings provide support for the hypothesis that the microbiology of urine colonization differs with age, and they are in agreement with the microbiological differences that have been observed in human patients, particularly those with catheter-associated UTIs (5,(12)(13)(14)(15)(16)(17). While parameters such as weight loss and white blood cell counts differed with age, these differences were not useful for predicting disease severity.…”

“…There is mounting evidence that the microbiology of ABU and UTI changes with age. For instance, Staphylococcus saprophyticus and Escherichia coli are more frequently identified in younger individuals than in older adults, while Proteus mirabilis, Enterococcus species, and Streptococcus agalactiae are more common in older adults, especially those in nursing facilities (5,(12)(13)(14)(15)(16). We recently determined that P. mirabilis was the most common organism in catheter-associated UTIs experienced by a cohort of nursing home residents (17), which is consistent with findings of previous studies (18)(19)(20).…”

“…Las ITU adquiridas en la comunidad que requieren hospitalización suelen asociarse a factores de riesgo como presencia de catéter urinario, antecedente de urolitiasis, ITU en los meses previos y la existencia de bacteriemia asociada 5,19,20 . En nuestro estudio, además de estos factores de riesgo señalados por Medina-Polo et al, la presencia de diabetes también se asocia a la existencia de bacteriemia.…”

“…La mortalidad en el SU es baja (0,4-0,6%) 2,8 , pero el hecho de la existencia de bacteriemia asociada en un paciente con ITU (más frecuente en inmunodeprimidos, ancianos, diabéticos, portadores de sondaje, entre otros factores de riesgo) se relacionará con una mayor mortalidad en su evolución inmediata 5,9 . De ahí la trascendencia de la sospecha y la confirmación de la existencia de bacteriemia en la evaluación de los pacientes con ITU en los SU, hecho que continúa siendo un reto hasta que los hemocultivos son procesados en microbiología 10 .…”

“…4,5 En gestantes, las ITUs suelen cursar con bacteriuria asintomática. 1,[5][6][7] El fallo terapéutico al tratamiento empírico se atribuye a mecanismos de resistencia bacteriana, principalmente a fluoroquinolonas, por modificación del sitio diana bacteriano 8 , a β-lactámicos mediante la producción de β-lactamasas plasmídicas, hiperproducción de β-lactamasa cromosómica de la clase C (AmpC) o expresión de β-lactamasas de espectro extendido (BLEE) 8 . La resistencia antimicrobiana constituye un problema sanitario a nivel asistencial y comunitario 9 .…”
