The Influence of Coalescent Microbiotic Particles From Water and Soil on the Evolution and Spread of Antimicrobial Resistance
AI summary Read the abstract
This review examines how microbiotic particles in water and soil serve as hotspots for bacterial interactions, facilitating the evolution and horizontal transfer of antimicrobial resistance genes between ecologically distant bacterial species through biofilm formation on particle surfaces.
Water and soil contain a multiplicity of particulate material coated with bacterial populations and communities. Microbiotic particles are any type of small particle (measuring less than 2 mm) to which bacteria and other microbes attach, resulting in medium to long-term colonization. This study reviews the interactions of ecologically distant bacterial organisms on microbiotic particles in soil and water as a method for explaining the evolution and spread of antibiotic resistance traits. These particles include bacteria-bacteria aggregates, which can merge with particles from fungi, protozoa, phytoplankton, zooplankton, and biodetritus resulting from animal and vegetal decomposition, humus, mineral particles (clay, carbonates, silicates), and anthropogenic particles (including wastewater particles and microplastics). In turn, these complex particles can interact and coalesce. Natural phenomena (waterflow, tides, tsunamis, currents, and strong winds) and anthropogenic activity (agriculture, waste-water management, mining, excavation/construction) favor the interaction and merging of microbiotic particles in soil and water, resulting in enhanced recombinant communities capable of exchanging genetic material, including antimicrobial resistance genes, particularly in antimicrobial-polluted environments. In this review, we propose that the worldwide spread of antimicrobial resistance might be related to the environmental dynamics of microbiotic particles, and we discuss possible methods for reducing this problem that threatens One Health and Planetary Health.

Microbiotic particles in water and soil, water-soil microbiota coalescences, and antimicrobial resistance
AI summary Read the abstract
This paper explores how bacteria attach to tiny particles in water and soil, forming communities that may carry antimicrobial resistance genes. Microplastics, sediment grains, and other particles act as surfaces where antibiotic-resistant bacteria can accumulate and spread. Understanding these 'microbiotic particles' is important for tracking how antibiotic resistance moves through the environment.

This review examines how micro- and nanoplastics act as vectors for antibiotic resistance genes, facilitating their spread through environmental and biological systems by creating selective pressure and hosting microbial communities that exchange resistance determinants.
The Microplastic–biofilm–resistome Nexus: the Role of Environmental Microplastics in the Formation and Dissemination of Antibiotic-resistant Bacteria and the Potential Consequences for Human Health
AI summary Read the abstract
Tiny plastic bits (microplastics) that end up in water and soil aren't just pollution, they can act like rafts where bacteria cluster together and swap genes that help them resist antibiotics. This review pulls together existing research suggesting these plastic "biofilms" could be a hidden pathway for drug-resistant germs to spread through the environment and potentially reach humans. While more research is needed to confirm real-world health risks, it's a reminder that plastic pollution and the growing problem of antibiotic resistance may be more connected than we think.

Tiny plastic particles floating in water and soil aren't just pollution, they can act like rafts where bacteria cluster together and swap genes that help them resist antibiotics. This review pulls together existing research suggesting that these plastic-bacteria communities could be a hidden pathway for drug-resistant "superbugs" to spread through the environment and potentially reach humans. While more research is needed to confirm the real-world health risk, it's a reminder that plastic pollution may have ripple effects beyond what we can see.

AI summary Read the abstract
This study examined how microplastics facilitate antimicrobial resistance by acting as a surface for the co-selection of resistant bacteria, finding that plastic surfaces enrich resistance genes and transfer-capable elements in aquatic environments.
