[ES]: [Introducción]: La realización de un antibiograma rápido sigue siendo un reto para los laboratorios de Microbiología Clínica. [Métodos]: Se ha realizado una mejora en el antibiograma colorimétrico realizado mediante resazurina en estafilococos y enterococos. El diseño del método se realizó mediante el uso de dos cepas de colección que presentan una sensibilidad conocida. Este procedimiento se validó posteriormente frente a los métodos comerciales mediante el procesamiento de 15 cepas de estafilococos y 15 de enterococos aisladas de pacientes. [Resultados]: Se ha obtenido un 100% de concordancia entre la sensibilidad obtenida mediante resazurina y la obtenida mediante los métodos comerciales (E-test, MicroScan and VITEK2). [Conclusión]: Mediante el uso de resazurina es posible obtener un antibiograma en estafilococos y enterococos en menos de dos horas de forma fiable.
[EN]: [Introduction]: Rapid determination of the antibiotic susceptibility test in bacteria remains a challenge for Clinical Microbiology laboratories. [Methods]: An improvement in the colorimetric antimicrobial susceptibility testing performed with resazurin in enterococci and staphylococci has been carried out. The design of method was performed using two collection strains, which have a known susceptibility. This procedure was then validated against standard commercial methods on 15 strains of staphylococci and 15 strains of enterococci from patients. [Results]: The essential agreement between the colorimetric method and commercial methods (E-test, MicroScan and VITEK2) was 100%. [Conclusion]: Resazurin allows us to obtain a reliable antibiotic susceptibility test in staphylococci and enterococci in less than two hours.
