Background: Today bacterial resistance is a global problem, it is estimated that in 2050 it could reach 10 million deaths per year. Bacterial resistance can be caused by different mechanisms, in the case of beta-lactams they include the production of flow pumps, the modification or reduction of porin production, alteration of penicillin-binding proteins and production of an enzyme capable of inactivating the antibiotic.
Objective: To describe the main bacterial agents reported in the Hospital para el Niño de Toluca and their sensitivity pattern.
