Antimicrobial Drug Resistance (AMR)
AMR is said to be the ability of a microbe to withstand the effects of medication that once might successfully treat the microbe. The word antibiotic resistance (AR or ABR) is a detachment of AMR, as it relates only to the bacteria becoming resistant to antibiotics. Resistant microbes are more problematic to treat, requiring alternative medications or higher doses of antimicrobials. These methodologies may be more expensive, higher toxicity risk or both. Microbes resistant to numerous antimicrobials are called multidrug resistant (MDR). The classes of drug resistance are extensively drug- resistant (XDR) and totally drug- resistant (TDR).
