The mechanisms of resistance are varied. Bacteria can acquire resistance genes through mutations or by transferring genetic material from other resistant bacteria via plasmids. This can happen in humans, animals, or the environment. For example, E. coli resistant to third-generation cephalosporins – a critical class of antibiotics – has spread worldwide, largely through contaminated food and water. Once a resistance gene emerges, it can jump between bacterial species, rendering entire classes of antibiotics ineffective. and the necessity of proper
