Antibiotic Resistance
Antibiotic resistance is the reduced susceptibility of bacteria to antibiotic drugs that ordinarily inhibit or kill them. This resistance develops via spontaneous genetic mutation or horizontal gene transfer.
Overview
Resistance mechanisms emerge through mutations affecting drug targets or via mobile genetic elements, including plasmids, transposons, and bacteriophages, that transfer resistance determinants across bacterial lineages. Selective pressure exerted by antibiotic exposure favors the survival and multiplication of resistant bacteria, allowing them to displace susceptible strains within shared environments.
Why it matters
Drug-resistant bacterial infections reduce the efficacy of standard antimicrobial regimens and increase clinical morbidity. Surgical operations, chemotherapy, and organ transplantation face elevated risks when prophylactic and therapeutic antibiotics fail to prevent secondary bacterial infections.
