Antibiotics work on various types of infections caused by bacteria.
They do not work with infections that are caused by a virus, such as colds, flus and most sore throats. Antibiotics are produced either from a mold, a fungus or synthetically. They include medications such as, amino glycoside, macrolide, penicillin, tetracycline, and cephalosporin. Some antibiotics are effective against only certain types of bacteria. Others can effectively fight a wide range of bacteria.
