Evaluation of a Loop-Mediated Isothermal Amplification assay to detect carbapenemases from Acinetobacter spp. directly from bronchoalveolar lavage fluid

Carbapenem-resistant Acinetobacter spp. mainly Acinetobacter baumannii are frequently causing nosocomial infections with high mortality. In this study, the efficacy of the Eazyplex® SuperBug Complete A system (Amplex Diagnostics GmbH, Gars-Bahnhof, Germany), based on loop-mediated isothermal amplification (LAMP), to detect the presence of carbapenemases in Acinetobacter spp. directly from bronchoalveolar lavage samples was assessed, detecting all tested carbapenemases in less than 30 minutes with a sensitivity of 103 CFU/ml.
