Antimicrobial resistance (AMR) refers to microorganisms' ability to survive or proliferate in the presence of medications that are intended to inhibit or kill them. Antimicrobials are medications that are used to treat infections caused by microorganisms like bacteria, fungi, viruses, and protozoan parasites. Standard therapies are often ineffective when microorganisms grow resistant to antimicrobials, and in other circumstances, no medications are available. As a result, treatments are ineffective. In humans, animals, and plants, this causes illness and death. Antimicrobial resistance (AMR) has emerged as one of the most serious public health issues of the twenty-first century, posing a threat to the effective prevention and treatment of an ever-widening range of infections caused by bacteria, parasites, viruses, and fungi that are no longer susceptible to common antibiotics. Bacteria that cause common or serious infections have developed resistance to each new antibiotic that comes to market over several decades, to variable degrees. Faced with this fact, immediate action is required to avert a looming global health-care crisis.
