Antimicrobial resistance (AMR) is the capability of a microbe to prevent the effects of medication already used to treat them. Resistance emerges through one of three manners: natural resistance in certain types of genetic mutation, bacteria, or by one species acquiring resistance from another. Resistance can be present automatically because of accidental mutations; or progressive buildup over time, and because of over usage or misuse of antimicrobials or antibiotics. Resistant microbes are difficult to treat, compelling another medications or higher doses, which may be harmful or costly. Antimicrobial resistance is one of the causes for millions of deaths worldwide every year.
