Destroying infectious microorganisms or abnormal cells

Infectious diseases occur when viruses, bacteria, protozoa or fungi invade the body. Antibiotics e.g. penicillin can destroy bacteria by killing them directly or by preventing them multiplying. Anti-fungals commonly used for infections of the skin and mouth (eg. …) work by disrupting infected cells. Other medicines work by killing abnormal cells, for example some anti-cancer drugs directly target and kill harmful cancer cells.
