Bacteriology & Antibiotics

Medical Use of Antibiotics

Antibiotics, also known as antibacterials, are medications that destroy or slow down the growth of bacteria. Antibiotics are powerful medicines that fight certain infections and can save lives when used properly. They either stop bacteria from reproducing or destroy them. Before bacteria can multiply and cause symptoms, the immune system can typically kill them. White blood cells (WBCs) attack harmful bacteria and, even if symptoms do occur, the immune system can usually cope and fight off the infection. They include a range of powerful drugs and are used to treat diseases caused by bacteria. A doctor prescribes antibiotics for the treatment of a bacterial infection. It is not effective against viruses.
