Drug Resistance, Bacterial

Drug resistance, bacterial (also called antibiotic resistance) is an important health issue that occurs when bacteria become resistant to drugs typically used to treat bacterial infections. This resistance can be caused by improper use of antibiotics or due to certain bacteria developing genetic changes that enable them to survive in the presence of antibiotic type drugs. It can lead to infections that are difficult or impossible to treat and can cause serious or deadly health problems for humans and animals. As a result, drug resistance, bacterial is a growing global health concern that warrants research into new treatments and strategies to limit its spread.
