Antibiotics are chemicals that kill or inhibit the growth of bacteria and are used to treat bacterial infections. Antibiotics are produced in nature by soil bacteria and fungi. Antibiotics are also known as antibacterial and antimicrobial. Antibiotics prevent the bacterial cells from multiplying so that the bacterial population remains the same, thus allowing the host's defence mechanism to fight the infection or kill the bacteria.The first true antibiotic 'Penicillin' was discovered by Alexander Fleming in 1928. After the discovery of Penicillin many researchers using the similar discovery and production techniques, discovered many other antibiotics in 1940s and 1950s i.e., streptomycin, chloramphenicol, erythromycin, vancomycin, etc. This review is focused on the classification, discovery and mechanism of action of antibiotics so that it will help the future researchers to find the better antibiotics to overcome the antibiotic resistance problem.
