Definition: Antibiotic-resistant bacteria (ARB) are bacteria that have developed the ability to survive exposure to antibiotics designed to kill them or inhibit their growth. These bacteria can withstand antibiotic treatments, making infections caused by them more difficult or sometimes impossible to treat effectively. ARB is a subset of AMR, focusing specifically on bacterial resistance to antibiotics, while AMR encompasses a wider range of microorganisms and antimicrobial drugs. Related to nosocomial infections and pathogen characteristics.
