Carbapenem-resistant Acinetobacter baumannii (CRAB) represents a significant risk to public health worldwide. In this study, our objective was to determine by phenotypic tests the production of serine-carbapenemases and/or metallocarbapenemases in cultures of A. baumannii obtained from a Level III hospital in the district of Trujillo from June to August 2023, Peru. For this purpose, twenty cultures of A. baumannii isolated from clinical samples, with medium sensitivity and resistant to carbapenemics, were collected. The Internal Carbapenemics Inactivation Method (iCIM) was used for detection. Subsequently, the type of carbapenemases was determined by the combined disc test with EDTA (Ethylenediaminetetraacetic Acid) and PBA (Phenylboronic Acid). By iCIM, seventeen isolates were identified as positive for carbapenemase production, of which fifteen were producers of metallobetalactamases, thirteen producers of serine carbapenemases; twelve co-producers of both types of carbapenemases were also found. In conclusion, seventeen carbapenemase-producing cultures were detected, of which 88.2% were producers of metallobetalactamases, 76.5% producers of serine carbapenemases and 71% co-producers of both types of carbapenemases.
