ABSTRACT
Usually, antibacterial agents are used in the medication of bacterial infections. Antibacterial agents are originated from any substance that is of natural, semisynthetic, or synthetic origin. They can successively kill or inhibit the growth of microorganisms while causing little or no damage to the host cell. Generally, the word antimicrobial was obtained from the combination of the Greek words “anti” meaning against, “mikros” meaning little, and “bios” meaning life. Antimicrobial agents act against all types of microorganisms such as bacteria (antibacterial), viruses (antiviral), fungi (antifungal), and protozoa (antiprotozoal).
