Abstract:
Antimicrobial resistance (AMR) represents a critical obstacle to public health worldwide, due to the high incidence of strains resistant to available antibiotic therapies. In recent years, there has been a significant increase in the prevalence of resistant epidemic strains, associated with this, public health authorities have been alarmed about a possible scenario of uncontrolled dissemination of these microorganisms and the difficulty in interrupting their transmission, as nosocomial pathogens with resistance profiles previously considered sporadic. They become frequent bacteria in the community. In addition, therapy for infections caused by these pathogens is based on broad-spectrum antibiotic therapy, which favors an increase in the tolerance of remaining bacterial cells and is commonly associated with a poor prognosis. In this review, we present the current status of epidemic strains of methicillin-resistant Staphylococcus aureus (MRSA), Vancomycin-resistant Enterococcus (VRE), MDR Mycobacterium tuberculosis, extended-spectrum β-lactamase-producing Enterobacterales (ESBL), Klebsiella pneumoniae carbapenemase (KPC), and-New Delhi Metallo-beta-lactamase-producing Pseudomonas aeruginosa (NDM).
Insights
Antimicrobial resistance (AMR) is a global health crisis, with rising epidemic strains like MRSA and VRE becoming common. This review examines the status of these dangerous, drug-resistant bacteria.
Area of Science:
- Microbiology
- Public Health
- Infectious Diseases
Background:
- Antimicrobial resistance (AMR) poses a critical global public health threat.
- Increasing prevalence of epidemic resistant strains, including nosocomial pathogens, is alarming.
- Broad-spectrum antibiotic use exacerbates resistance and leads to poor patient prognosis.
Purpose of the Study:
- To review the current status of prevalent epidemic antimicrobial-resistant strains.
- To highlight the public health implications of increasing bacterial resistance.
- To provide an overview of key resistant pathogens.
Main Methods:
- Literature review of current scientific publications.
- Analysis of epidemiological data on resistant strains.
- Synthesis of information on Methicillin-resistant Staphylococcus aureus (MRSA), Vancomycin-resistant Enterococcus (VRE), MDR Mycobacterium tuberculosis, Extended-spectrum β-lactamase-producing Enterobacterales (ESBL), Klebsiella pneumoniae carbapenemase (KPC), and New Delhi Metallo-beta-lactamase-producing Pseudomonas aeruginosa (NDM).
Main Results:
- Epidemic strains of MRSA, VRE, MDR TB, ESBL, KPC, and NDM-producing P. aeruginosa are increasingly prevalent.
- These resistant pathogens are transitioning from hospital-acquired to community-acquired infections.
- Therapeutic challenges are compounded by limited treatment options and the rise of multidrug resistance.
Conclusions:
- The escalating crisis of antimicrobial resistance demands urgent attention and novel therapeutic strategies.
- Understanding the current status of these epidemic strains is crucial for effective public health interventions.
- Continued surveillance and research are essential to combat the spread of resistant bacteria.
