During the last years, antibiotics have been losing their effectiveness against bacteria, because bacteria have gotten used to it, developing resistance. This situation is worrying the health field, since antibiotics have many uses in the world of medicine. For this reason, due to the magnitude and importance of the problem at a global level, it has been decided to develop the following research. The main objective is to check the resistance that bacteria gain against antibiotics. To verify this, an experiment has been carried out in the laboratory to see the rapid evolution of bacteria and, thanks to it, the resistance. The results obtained were not the expected ones. Even though the bacteria have surpassed some antibiotic, it has not been verified if more resistance is gained as the dose of it is more concentrated.
