The Short Answer
It’s pretty much all down to the methods that they use to evade the immune system and their relative effectiveness. Some bacteria hide inside your own cells. Some bacteria find a little pocket where they can develop their own environment (ulcers), some kill off your cells to get a nice oxygen-less space, and some activate your immune system so strongly that your own immune cells start attacking you. Bacteria want to maintain a balance where you’re sick enough to allow them to spread but not so sick that you die without spreading the disease to another place where it can grow. Basically, some bacteria (generally the ones that don’t spread super easily) are just better at evading the immune system, so we have to give antibiotics. Some don’t need to survive too long because they spread quickly to other people. The overwhelming majority of bacteria are either blocked by our skin/mucus, or they get the shit beat out of them by our incredibly powerful immune system
