Mechanisms of Antibiotic Resistance - PMC - PubMed Central …
In this chapter, we will describe in detail the major mechanisms of antibiotic resistance encountered in clinical practice providing specific examples in relevant bacterial pathogens.
An overview of the antimicrobial resistance mechanisms of bacteria
The main mechanisms of resistance are: limiting uptake of a drug, modification of a drug target, inactivation of a drug, and active efflux of a drug. These mechanisms may be native to the microorganisms, or acquired from other microorganisms.
Antibiotic resistance | Definition, Mechanisms, Examples, & Facts ...
2024年12月19日 · Antibiotic resistance, loss of susceptibility of bacteria to the killing (bacteriocidal) or growth-inhibiting (bacteriostatic) properties of an antibiotic agent. When a resistant strain of bacteria is the dominant strain in an infection, the infection may be untreatable and life-threatening.
