Multidrug resistant Enterobacteriaceae in New Zealand: a current perspective

Area of Science:

• Microbiology
• Infectious Diseases
• Public Health

Background:

• Enterobacteriaceae, especially extended-spectrum β-lactamase (ESBL)-producing strains, are a significant challenge due to multidrug resistance.
• Interactions between humans, animals, and the environment create pathways for the transmission of antimicrobial-resistant bacteria.

Purpose of the Study:

• To review the mechanisms and transmission pathways of multidrug resistance in Enterobacteriaceae, focusing on ESBL-production.
• To inform prevention and control strategies for antimicrobial resistance through a better understanding of bacterial sharing between species.

Main Methods:

• Review of existing literature on multidrug resistance mechanisms and transmission routes.
• Emphasis on the role of human-animal interactions and the food chain in bacterial dissemination.
• Discussion of antimicrobial stewardship and infection control measures.

Main Results:

• Identified key transmission pathways for ESBL-producing Enterobacteriaceae between humans, animals, and the environment.
• Highlighted the risk of zoonotic and reverse-zoonotic disease transmission.
• Stressed the importance of improved antimicrobial stewardship and surveillance.

Conclusions:

• Effective control of antimicrobial resistance requires a One Health approach, integrating human, animal, and environmental health.
• Enhanced surveillance, infection prevention, and understanding of prescribing practices are essential.
• Prospective studies are needed to identify risk factors for antimicrobial resistance.
