Background: New Delhi Metallo-b-lactamase (NDM-1) is an enzyme emerging around the world conferring resistance to a wide range of β-lactams agents and whose early detection is extremely important. We proposed to standardize the detection of the bla gene using the LOOP-mediated isothermal amplification technique (LAMP).
Methods: In all, 14 Gram-negative bacterial strains isolated from patients presenting pneumonia associated with mechanical ventilation were used for the bla standardization by LAMP.
