La frecuencia de estas infecciones se presenta en el reemplazo articular de rodilla de 0.68 a 1.60% en comparación con el de cadera de 0.67 a 2.4%.  Objetivo:  identificar cuáles son los agentes etiológicos más frecuentes en infecciones periprotésicas en adultos mayores y en pacientes con cirugía primaria de cadera y rodilla.  Material y métodos:  Se realizó un estudio observacional, transversal y retrospectivo, tipo serie de casos en un período comprendido de Junio de 2011 a Diciembre de 2014, se incluyeron pacientes mayores de 60 años con diagnóstico de infección periprotésica mediante dos cultivos positivos con antibiograma.  Resultados:  Se evaluaron 62 pacientes, 59.7% presentaron infecciones de rodilla y 40.3% de cadera, 59% fueron infecciones por Escherichia coli y 22% por Staphylococcus aureus. El antibiótico que mejor sensibilidad reportó fue trimetoprim-sulfametoxazol (40.3% )y el de mayor resistencia fue penicilina G (32.2%).  Conclusión:  Los agentes etiológicos más frecuentes fueron Escherichia coli y Staphylococcus aureus.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract:  Background:  The most common etiological agents in periprosthetic infections are Escherichia coli and Staphylococcus aureus. The frequency of these infections are found in knee replacement with 0.68 to 1.60% compared to the hip with 0.67 to 2.4%.  Objective:  To identify what are the most common etiologic agents in periprosthetic infections in elderly patients with primary hip and knee surgery.  Material and methods:  An observational study, transverse and retrospective case series was performed in a period from June 2011 to December 2014, patients over 60 years with a diagnosis of periprosthetic infection by two positive cultures with antibiograma.  Results:  62 patients were evaluated 59.7% were infections of knee and hip 40.3%, 59% were infections by Escherichia coli and Staphylococcus aureus 22%. The best sensitivity reported antibiotic trimethoprim-sulfamethoxazole was 40.3%. The largest penicillin G resistance 32.2%.  Conclusion:  The most common causative agents were Escherichia coli and Staphylococcus aureus.]]></p></abstract>
