Resumen:
Atomic force microscopy (AFM) is a widely used tool in microbiology to image and explore the nanomechanical properties of bacteria. In this work, we employed this technique to study the membrane properties of Bordetella pertussis, a Gram-negative bacterium that colonizes human airway and produces whooping cough. More specifically, we analyzed the effect of two antibiotics, erythromycin and ampicillin, on the bacterial envelope and monitored cell wall stiffness modifications during virulence changes.
