Microplastic-associated antimicrobial resistance: an AI-aided systematic literature review and distribution mapping
AI summary Read the abstract
An AI-aided systematic literature review and distributional analysis examined microplastic-associated antimicrobial resistance (AMR) in aquatic and other environments. The authors found growing evidence that microplastics accelerate AMR spread, with important implications for environmental and health policy.
Plastic and microplastics are suspected to accelerate antimicrobial resistance (AMR) in aquatic and other environments. An increasing literature body offers insights into this with implications for health and environmental policy. Studies analysing the relationship vary greatly in design. Here we aim to map and summarize the extensive body of peer-reviewed articles on plastisphere-related AMR research.

AI-Based Analysis of Microplastics' Impact on Antibiotic Resistance Transmission in Aquatic Ecosystems

Researchers investigated how microplastic surfaces facilitate antibiotic resistance gene transmission in aquatic ecosystems using AI-based analysis, examining the role of plastisphere biofilms as vectors for horizontal gene transfer between bacterial communities.
Global surface-water microparticle carrier-load patterns across aquatic ecosystems: a spatial framework for prioritizing future plastisphere-associated antimicrobial resistance surveillance
AI summary Read the abstract
Researchers combined two global surface-water datasets (2013-2017, 2,399 samples) to map where plastic particles are commonly found in freshwater, estuaries, coastal areas, and open ocean. Particle detection and concentration were highest in open ocean samples, and the study identified 28 locations as priorities for future, separate testing of antibiotic-resistant microbes, not confirmed resistance hotspots themselves.
Microplastics enhance the enrichment and dissemination of antibiotic resistance genes in aquatic environments: A meta-analysis
AI summary Read the abstract
Tiny plastic particles in water aren't just pollution, this analysis of multiple studies found they nearly double the amount of antibiotic-resistant bacteria genes in aquatic environments, essentially acting as gathering spots where these genes multiply and spread more easily. This matters because antibiotic resistance is already a major public health threat, and if microplastics in our waterways are helping resistant bacteria thrive and share their resistance traits, that could make infections harder to treat down the line, especially since smaller plastic particles seemed to make the problem worse.
Influence of microplastics on antibiotic resistance genes across diverse environments: A comprehensive meta and machine-learning analysis
AI summary Read the abstract
This large-scale analysis examined how microplastics influence the spread of antibiotic resistance genes across different environments including intestines, wastewater sludge, plants, soil, and water. Researchers found that microplastics significantly boosted antibiotic resistance gene levels in gut, sludge, and plant settings, with particle size and concentration being the most important factors. The findings suggest that microplastic pollution may be helping spread antibiotic resistance, a serious public health concern, through multiple environmental pathways.
The Microplastic-Antibiotic Resistance Connection
AI summary Read the abstract
This review examined the link between microplastic pollution and antibiotic resistance, finding that microplastic surfaces in the environment selectively enrich antibiotic-resistant bacteria and resistance genes, creating hotspots that may amplify the spread of resistance far beyond clinical settings.
