Antibiotic resistance is a natural phenomenon amplified by inappropriate uses..
Antimicrobial resistance is the phenomenon whereby bacteria exposed to the same antibiotic for a prolonged period of time mutate and become resistant, which makes their control, difficult, if not impossible, with current treatments. This phenomenon stems from the process of natural selection. From the discovery of the first antibiotics, Alexander Fleming, discoverer of penicillin, had already revealed this major risk to their effectiveness for health in the long term. However, it has been seriously amplified by an excessive and inconsiderate use of antibiotics for 50 years, in both human and animal health. It is estimated, for example, that about 80% of the antibiotics sold in the United States are destined for animal husbandry. The first bacteria resistant to antibiotics appeared as early as the 1960s, very soon after the first treatments were marketed. Since then, antibiotic-resistant bacteria have been multiplying. Many bacteria that cause serious infections in humans, s
