Bacterial reproduction, antibiotic resistance, and evolution
Bacterial reproduction, antibiotic resistance, and evolution are three things that relate very closely to each other. In starting, during bacterial reproduction, different bacteria with different genes and DNA emerge, opening up the possibility of competition for the "fittest" bacteria to survive. An antibiotic resistance is built up when the weaker bacteria are easily killed off in the presence of an antibiotic. After the symptoms caused by the majority of the killed off bacteria disappear, an antibiotic taker will usually stop consumption. Unfortunately, the antibiotic taker doesn't realize that the stronger, and more "fit" bacteria were likely to survive and during the time of stopped consumption, have multiplied rapidly. When the person begins to re-take this antibiotic after the strong bacteria have started causing the previous symptoms once again, the bacteria now present are stronger than the aforementioned majority of weaker bacteria, and are able to fight against the pre-successful antibiotic. This resilience against the antibiotic was caused from the rapid bacterial reproduction that resulted in DNA-unique bacteria, and the fact that natural selection, an integral part of evolution, caused the bacteria with superior DNA to survive and further multiply to fight off the antibiotic.
