There are many different kinds of antibiotics that contain different substances. In simple terms, an antibiotic is a medical substance derived from chemical preparations, organic preparations, etc. that have been proven to kill bacteria, usually each type of antibiotic is targeted at specific types of bacteria since not all antibiotics are effective against all bacteria. The substances usually destroy the organism's cell walls so they can no longer function, or damage the ability of the bacteria to reproduce. They destroy them or inhibit the growth and/or functions of these harmful microorganisms.
