This figure is a schematic diagram giving an overview of the mechanisms of antibiotic resistance. The bacterial cell is represented by a brown oval and the cell wall/membrane is represented in orange surrounding the bacterial cell. Antibiotics (shown as blue spheres) are shown (using red arrows) crossing the cell wall and binding to their target (in green). Enzymes that destroy or modify the antibiotic or target are shown in orange. The following mechanisms are illustrated; modifying the target, protecting the target, amplifying the target, preventing antibiotic entry, increasing efflux, modifying the antibiotic and destroying the antibiotic.
