In my recent deep dive into the world of antibiotics, I've been exploring how Ampicillin interacts with our immune system. Ampicillin, a type of penicillin, works by preventing bacteria from building their cell walls, thereby killing them off. However, it's important to note that it doesn't discriminate - it can kill off our body's beneficial bacteria too. This can potentially weaken our immune system, leaving us more susceptible to other infections. So, while Ampicillin is a powerful tool against infections, it's crucial to use it responsibly to maintain our body's natural defenses.
