Abstract:
Resistance to antimicrobial drugs is increasing at an alarming rate among both gram-positive and gram-negative bacteria. Traditionally, bacteria resistant to multiple antimicrobial agents have been restricted to the nosocomial environment. A disturbing trend has been the recent emergence and spread of resistant pathogens and resistance traits in nursing homes, the community, as well as in hospitals. This article reviews the epidemiology, molecular mechanisms of resistance, and treatment options for pathogens resistant to antimicrobial drugs.
Insights
Antimicrobial drug resistance is rising in gram-positive and gram-negative bacteria, spreading beyond hospitals into communities. This review covers the epidemiology, resistance mechanisms, and treatment for drug-resistant pathogens.
Area of Science:
- Microbiology
- Infectious Diseases
- Pharmacology
Background:
- Increasing rates of antimicrobial drug resistance in gram-positive and gram-negative bacteria pose a significant global health threat.
- Traditionally confined to healthcare settings, resistant pathogens are now emerging in community and long-term care facilities.
Purpose of the Study:
- To review the current epidemiology of antimicrobial resistance.
- To explore the molecular mechanisms underlying bacterial resistance.
- To discuss available treatment options for resistant infections.
Main Methods:
- Literature review of epidemiological data on antimicrobial resistance.
- Analysis of molecular mechanisms of resistance in bacteria.
- Synthesis of current treatment strategies and guidelines.
Main Results:
- Antimicrobial resistance is a growing problem affecting both hospital and community settings.
- Diverse molecular mechanisms contribute to the spread of resistance traits.
- Effective treatment options are becoming more limited.
Conclusions:
- Urgent strategies are needed to combat the increasing prevalence of antimicrobial resistance.
- Understanding resistance mechanisms is crucial for developing new therapies.
- Multifaceted approaches are required to manage drug-resistant pathogens effectively.
