It's your own immune system that's developed resistance and resilience to this bacteria that fights it off, and you actually never get the infection, which is very different from, say, our treatments. Right? In that case, you get the infection, you're exposed to the bacteria, you're sick, and then you take, say, an antibiotic which cures it, and those drugs are actually working to kill the bacteria.
Es tu sistema inmunológico, que ha desarrollado resistencia, y que combate la bacteria, y, de hecho, nunca te infectas. Lo cual es muy diferente a nuestros tratamientos, ¿no? En ese caso, contraes la infección, estás expuesto a la bacteria, te enfermas, y tomas un antibiótico que te cura y esas medicinas actúan, de hecho, matando a la bacteria.
