Antibiotic resistance: the current position and the molecular mechanisms involved
1Division of Infectious Diseases, St George's Hospital Medical School, London.
Abstract:
The introduction of antibiotics heralded a new era in the chemotherapy of infectious diseases, but over the ensuing years bacterial evolutionary responses to the selective pressure of antibiotics have resulted in microorganisms resistant to virtually every known antibiotic. The consequences have been very important in clinical practice, as patients infected with a multi-resistant organism suffer increased morbidity and mortality and often require the use of expensive and potentially toxic antibiotic regimens in order to achieve effective, specific treatment.
Insights
Antibiotic resistance is a growing problem. Bacteria evolve to resist antibiotics, leading to harder-to-treat infections and increased patient mortality.
Area of Science:
- Microbiology
- Infectious Diseases
- Evolutionary Biology
Background:
- Antibiotics revolutionized infectious disease treatment.
- Bacterial evolution has led to widespread antibiotic resistance.
- Multi-resistant organisms pose significant clinical challenges.
Purpose of the Study:
- To highlight the clinical impact of antibiotic resistance.
- To underscore the challenges in treating multi-resistant infections.
Main Methods:
- Review of clinical outcomes.
- Analysis of treatment regimens for resistant infections.
Main Results:
- Increased morbidity and mortality in patients with multi-resistant infections.
- Necessity of using expensive and toxic antibiotic regimens.
Conclusions:
- Antibiotic resistance necessitates novel therapeutic strategies.
- Urgent need for new treatments to combat resistant bacteria.
