Antibiotic resistance is the ability of bacteria to resist the effects of an antibiotic â that is, the bacteria are not killed, and their growth is not stopped. Resistant bacteria survive exposure to the antibiotic and continue to multiply in the body, potentially causing more harm and spreading to other animals or people.
Gram-negative bacteria and mycobacteria are innately resistant to several antibiotics (such as macrolides) because their outer membrane restricts the influx of these drugs (Fig. 5a). Resistance to all major classes of ribosome-targeting antibiotics is also conferred to some extent by efflux in all bacteria (Fig. 5b).vercoming bacterial resistance. The global rise of multidrug-resistant bacteria, coupled with the paucity of novel antibiotics in the development pipeline, represents a major public health concern. Several strategies are underway to develop improved and novel antimicrobial agents.
