How do bacteria become resistant?
Some bacteria are naturally resistant to certain types of antibiotics. Bacteria can also become resistant by a genetic mutation or by acquiring resistance from another bacterium. Because bacteria can collect multiple resistance traits over time, they can become resistant to many different families of antibiotics, which allows the resistant bacteria to continue to live/and multiply even in the presence of antibiotic treatment.
