The discovery of antibiotics led to sigh of relief, that now no bacteria will reside in this planet. With time, the bacteria have become smarter, and along with it, massive usage of antibiotics in clinical practice has resulted in resistance of bacteria to antimicrobial agents. The following biochemical types of resistance mechanisms are used by bacteria: Antibiotic inactivation, target modification, altered permeability, and "bypass" metabolic pathway. Determination of bacterial resistance to antibiotics of all classes (phenotypes) and mutations that are responsible for bacterial resistance to antibiotics (genetic analysis) are helpful. Better understanding of the mechanisms of antibiotic resistance, will help clinicians regarding usage of antibiotics in different situations.
