How bacteria becomes resistant to antibiotics
Web5 de jun. de 2024 · Antibiotic resistance occurs due to changes, or mutations, in the DNA of the bacteria, or the acquisition of antibiotic resistance genes from other bacterial species through horizontal gene transfer. These changes enable the bacteria to survive the effects of antibiotics designed to kill them. WebBacterial resistance to antibiotics can be intrinsic or acquired. Intrinsic resistance results from a naturally occurring trait in a species, e.g., cephalosporin resistance in Enterococcus spp., and by implication all members of that species will exhibit that resistance pattern.
