Insights

Multi-resistant Enterobacterales (MRE) are a growing global threat, often spread through plasmid transfer. International travel and antibiotic use are key risk factors, necessitating a One Health approach for surveillance and control.

Area of Science:

  • Microbiology and Infectious Diseases
  • Antimicrobial Resistance
  • Public Health Surveillance

Context:

  • Global increase in Multi-resistant Enterobacterales (MRE).
  • Horizontal plasmid transfer as a primary resistance mechanism.
  • Disproportionate impact on low- and middle-income countries.

Purpose:

  • Highlight the importance of MRE surveillance in low-endemicity countries like Switzerland.
  • Identify key risk factors for MRE acquisition in travelers.
  • Emphasize the need for a comprehensive One Health strategy.

Summary:

  • MRE, often carrying genes for extended-spectrum beta-lactamases and carbapenemases, are increasing worldwide.
  • International travel, particularly to South/Southeast Asia, and antibiotic use during travel are significant MRE acquisition risks.
  • Animal and environmental factors also contribute to MRE prevalence.

Impact:

  • Informing targeted MRE surveillance and control strategies.
  • Guiding public health interventions for international travelers.
  • Promoting a One Health framework to combat antimicrobial resistance.

Drugs Affecting GI Tract Motility: Antimicrobials as Antidiarrheal Agents

Acute diarrhea, a common gastrointestinal disturbance, is characterized by the rapid evacuation of fluid stools, leading to an excessive weight in fluid. This condition typically arises from disorders affecting intestinal water and electrolyte transport. It can be triggered by an increased osmotic load within the intestine, excessive secretion of electrolytes and water, mucosal exudation of protein and fluid, or altered intestinal motility. The primary risks of acute diarrhea are dehydration...

Defense Against Bacterial Pathogens

The human immune system is a complex network of cells, tissues, and organs that work together to defend the body against bacterial infections. It consists of various immune cells, each playing a specific role in the defense mechanism.
Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...

Transmission-based Precautions I: Contact, Enteric, and Droplets

Transmission-based precautions are for patients known to be infected or suspected to be infected or colonized with organisms that pose a significant risk to others. Some transmission-based precautions include contact, enteric, and droplet.
Contact Precautions:
Contact precautions are the measures taken to prevent the transmission of infectious agents, especially epidemiologically important microorganisms such as MRSA or influenza, primarily transmitted through direct or indirect contact with an...
