Although we often think of bacteria as enemies, most of them are actually our allies: they live with us and help keep us healthy. However, some have learned to resist antibiotics, posing a serious threat to global health. This article explains how bacteria share genetic information through a process known as horizontal gene transfer, which allows them to become stronger and adapt quickly. Through clear examples and curious comparisons —such as “bacterial sex” or “DNA eating”— it shows how these microorganisms learn and defend themselves, and why the responsible use of antibiotics is key to curbing antimicrobial resistance.
