The role of antibiotics is the pressure on the environment;
those that survive will survive and reproduce. They will multiply.
They pass on their traits to future generations, and this event
will be a generation of total resistance.
The mechanism of evolution proposed by Darwin is natural selection.
Because resources are limiting in nature, organisms with genetic
traits conducive to survival and reproduction tend to leave more
offspring than their peers, leading to an increase in the frequency
of these traits over several generations.
That's because taking them regularly until prescription drugs help ensure that the germs that cause the disease are killing or prevented from multiplying. If we stop using antibiotics too soon, we may not be able to kill the bacteria that cause the infection. The surviving bacteria gather, and the infection worsens. Another is that if the bacteria mutate and become resistant to antibiotics, it may be difficult for doctors to stop the infection.
Antibiotics act as an artificial selecting agent on bacterial strains . It eliminates bacteria which are susceptible to it. The resistant strains survive, multiply and pass on their resistance genes to their offsprings. This leads to the emergence of a new bacteria population which is completely resistant to the antibiotic.
The selection of fitter individuals which can adapt to changing environment , called natural selection, was first proposed by Charles Darwin. He proposed that nature has limited resources and their availability is subject to changes in the environment. Thus the organisims with beneficial traits (adaptable traits) have higher survival and thus enjoy higher reproductive success. Higher reproductive fitness means these selected organisms bear more offsprings than other individuals of the population with lower reproductive fitness. This leads to a gradual increase in their offsprings with these favourable traits over many generations.
Due to this, it is advised to take the prescription drugs regularly and complete the full course. This ensures that the disease causing bacteria are completely exterminated and thus their multiplication and selection of resistant bacteria is stopped. When an individual fails to complete the course, few bacteria sustain in the body which can cause infection. Now these suviving bacteria develop resistance to the antibiotic through mutation. This poses a serious and difficult situation for the doctors since controlling and obliterating the infection is not possible with readministration of previous treatement.
