Antibiotic resistance is the ability of a microorganism to withstand the effects of an antibiotic. It is a specific type of drug resistance. Antibiotic resistance evolves naturally via natural selection through random mutation , but it could also be engineered by applying an evolutionary stress on a population. Antibiotics disrupt essential structures or processes in bacteria. This in turn either kills the bacteria or stops them from multiplying. Bacteria have in turn evolved many antibiotic resistance mechanisms to withstand the actions of antibiotics. How bacteria resist antibiotics? There are two main ways for bacteria to withstand the effects of a antibiotic : To stop the antibiotic from reaching its target at a high enough concentration.

Benefits of Antibiotics: Antibiotics have not only saved patients lives, they have...
