What is antibiotic resistance?

Wondering what is antibiotic resistance? To explain what is antibiotic resistance, let us put it in a simple definition form. Antibiotic resistance can be defined as the ability of a microorganism to destroy or be unaffected by an antibiotic, or prevent it from entering the microorganism. Micro-organisms acquire antibiotic resistance by DNA mutations, sexual DNA transformation or harboring plasmids. Most scientists blame the bacterial antibody resistance to overuse of medications and household disinfectants.
