RESUMEN

Las infecciones nosocomiales (IN) son importante causa de morbimortalidad e incremento de costos. A pesar del aumento de bacterias Gram positivas como agentes etiológicos de estas infecciones, los Gram negativos siguen siendo causa importante en México y en el mundo. Uno de los retos en el diagnóstico oportuno y el tratamiento específico de las IN por Gram negativos es la resistencia a los betalactámicos a través de producción de betalactamasas de espectro extendido (BLEEs) el cual se considera el principal mecanismo de resistencia frente a cefalosporinas de tercera, cuarta generación y monobactámicos.
