Antibiotic Resistance: What Is It, Complications & Treatment
2023年10月19日 · Antibiotic resistance is when bacteria change to resist antibiotics that used to effectively treat them. This makes certain bacterial infections difficult to treat. Overuse and misuse of antibiotics cause antibiotic resistance.
Antibiotic Resistance - StatPearls - NCBI Bookshelf
2023年6月20日 · Antibiotic resistance occurs when bacteria evolve to evade the effect of antibiotics through multiple different mechanisms. Dissemination of antibiotic resistance genes is an ecological and public health concern.
Antibiotic Resistance: How It Happens and How to Prevent It
2024年7月17日 · Antibiotic resistance is a worldwide problem that happens when bacteria develop ways to combat the effects of the antibiotics designed to kill them. People do not become resistant to antibiotics. Instead, bacteria naturally develop mechanisms that make it difficult for antibiotics to kill them.
Antimicrobial resistance - World Health Organization (WHO)
2023年11月21日 · The 2022 Global Antimicrobial Resistance and Use Surveillance System (GLASS) report highlights alarming resistance rates among prevalent bacterial pathogens. Median reported rates in 76 countries of 42% for third-generation cephalosporin-resistant E. coli and 35% for methicillin-resistant Staphylococcus aureus are a major concern.
About Antimicrobial Resistance - CDC
Antimicrobial resistance accelerates when antibiotics and antifungals pressure bacteria and fungi to adapt. The antimicrobial-resistant germs survive, multiply and spread to other germs. These surviving germs have resistance traits in their DNA that can spread to other germs.
An overview of the antimicrobial resistance mechanisms of bacteria
Apparently most pathogenic microorganisms have the capability of developing resistance to at least some antimicrobial agents. 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.
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.
Bacterial Resistance to Antimicrobial Agents - PMC - PubMed …
In particular, bacteria with resistance to multiple antimicrobial agents can confound chemotherapeutic efficacy towards infectious diseases. Multidrug-resistant bacteria harbor various molecular and cellular mechanisms for antimicrobial resistance.
The Mechanism of Bacterial Resistance and Potential …
In this review, nine identified drug resistance mechanisms are summarized, which enhance the retention rate of bacteria under the action of antibiotics and promote the distribution of drug-resistant bacteria (DRB) in the population.
Antimicrobial Resistance: Definition, Causes & Prevention
Antimicrobial resistance happens when microbes (like bacteria and fungi) are able to outsmart medications providers use to treat them. This can happen naturally or when certain medications are used a lot — germs can develop changes (mutations) …
