ClearMarine plastisphere selectively enriches microbial assemblages and antibiotic resistance genes during long-term cultivation periods
Researchers placed four types of common microplastics in a marine environment for over 100 days and found that bacterial communities and antibiotic resistance genes accumulated on the plastic surfaces over time. PVC microplastics were particularly effective at concentrating resistance genes, and a key gene-transfer element was found on all plastic types. These results show that microplastics floating in the ocean act as hotspots for antibiotic-resistant bacteria, which could eventually reach humans through seafood or water.
New insight into the effect of microplastics on antibiotic resistance and bacterial community of biofilm
Researchers found that different types of microplastics promote distinct biofilm communities and enhance antibiotic resistance gene proliferation compared to natural substrates, suggesting microplastics serve as unique platforms for the spread of antimicrobial resistance.
Antibiotic resistant bacteria colonising microplastics in the aquatic environment: An emerging challenge
Researchers reviewed how microplastics in aquatic environments act as surfaces where antibiotic-resistant bacteria can grow and swap resistance genes with each other, raising concern that contaminated seafood and water could transfer these hard-to-treat bacteria to humans.
The impact of microplastics on antibiotic resistance genes, metal resistance genes, and bacterial community in aquaculture environment
Researchers discovered that microplastics in fish farming environments carry significantly higher levels of antibiotic resistance genes and disease-causing bacteria like Brucella and Pseudomonas compared to surrounding water. This means microplastics may act as floating platforms that help spread antibiotic-resistant infections through aquaculture, potentially reaching humans who consume the seafood.
Detection of antimicrobial resistance in Escherichia coli and Salmonella spp. Originated from cultivated oysters and estuarine waters
This study detected antimicrobial-resistant bacteria in oysters and estuarine waters, raising concerns about how aquatic environments serve as reservoirs for antibiotic resistance that can reach humans through seafood consumption. The findings are relevant to microplastic research because microplastics are known to harbor and concentrate antibiotic resistance genes on their surfaces.
Potential risks of microplastics combined with superbugs: Enrichment of antibiotic resistant bacteria on the surface of microplastics in mariculture system
Microplastics in a mariculture (sea farming) system were found to selectively enrich antibiotic-resistant bacteria on their surfaces compared to surrounding water, creating hotspots of antibiotic resistance in food production environments. This dual threat - microplastics acting as both pollutants and carriers of resistant pathogens - has significant implications for seafood safety.
Selective enrichment of bacterial pathogens by microplastic biofilm
Researchers incubated biofilms on microplastics and natural substrates in freshwater and found that microplastic surfaces selectively enriched bacterial pathogens and antibiotic resistance genes compared to rock and leaf surfaces. The study suggests that microplastics in waterways may serve as hotspots for harmful bacteria and contribute to the spread of antibiotic resistance in the environment.
Effects of aged microplastics on the abundance of antibiotic resistance genes in oysters and their excreta
Researchers studied how aged microplastics affect the abundance of antibiotic resistance genes in oysters and their excreta. The study found that microplastics can serve as carriers for antibiotic resistance genes in filter-feeding organisms, potentially exacerbating the spread of antibiotic resistance in aquaculture environments where plastic contamination is widespread.
Bacterial pathogen assemblages on microplastic biofilms in coastal waters
Researchers incubated different types of microplastics in coastal waters for 21 days and analyzed the bacterial communities that colonized their surfaces. They found that while overall pathogen abundance was low, microplastic biofilms hosted a diverse array of potentially harmful bacteria whose composition varied by polymer type and water location. The study suggests that microplastics in coastal waters can serve as floating platforms for disease-causing microorganisms.
Exploring changes in microplastic-associated bacterial communities with time, location, and polymer type in Liusha Bay, China
Researchers tracked how bacterial communities colonizing different types of microplastics changed over time in an aquaculture bay in China. They found that both exposure duration and plastic type significantly influenced which bacteria grew on the surfaces, with hydrocarbon-degrading species becoming notably abundant. Concerning from a health perspective, the pathogenic bacterium Vibrio was detected on all microplastic samples, suggesting that floating plastics may serve as rafts for disease-causing organisms.
Assessment of Emerging Pathogens and Antibiotic Resistance Genes in the Biofilm of Microplastics Incubated Under a Wastewater Discharge Simulation
Researchers incubated common plastic types in flowing water that simulated wastewater discharge conditions for 10 weeks and studied the bacteria that colonized the plastic surfaces. They found that microplastics exposed to treated wastewater developed distinct bacterial communities compared to those in clean river water, including emerging pathogens and antibiotic resistance genes. The study suggests that microplastics in waterways receiving wastewater may serve as mobile platforms for spreading harmful bacteria and antibiotic resistance in the environment.
Alteration of microbial mediated carbon cycle and antibiotic resistance genes during plastisphere formation in coastal area
Researchers investigated how microplastic surfaces in coastal environments develop biofilm communities, known as the plastisphere, and whether these biofilms enrich antibiotic resistance genes. The study found that incubation time, habitat type, and microplastic aging state all significantly influenced biofilm composition, and that aged microplastics accumulated more antibiotic resistance genes than new ones, suggesting microplastics may serve as vectors for spreading resistant bacteria.

Selective enrichment of bacteria and antibiotic resistance genes in microplastic biofilms and their potential hazards in coral reef ecosystems
Researchers found that microplastic surfaces in coral reef waters selectively collect bacteria carrying antibiotic resistance genes, with the concentration of resistant bacteria linked to antibiotic levels in the surrounding water. The bacterial communities on microplastics were enriched for disease-related pathways compared to the surrounding seawater. This means microplastics in marine environments could serve as vehicles for spreading drug-resistant infections, posing risks to both coral ecosystems and human health.

Bacterial colonisation dynamics of household plastics in a coastal environment
This study tracked how quickly and what kinds of bacteria colonized common household plastics (including bottles, bags, and packaging) placed in a coastal estuary environment. Bacteria colonized all plastic types within days, and the communities that formed included potential human pathogens. Plastic-associated bacterial communities in coastal environments could pose public health risks through seafood contamination or contact with polluted water.
Formation of specific bacterial assemblages on sterile polyethylene microplastic particles added to a marine aquaria system
Researchers characterized bacterial assemblages that formed on sterile polyethylene microplastic particles after 12 weeks of incubation in marine aquaria, comparing the plastisphere communities to those on sterile sandy sediment and in water fractions to determine whether microplastics select for distinct or potentially pathogenic bacterial communities. The study found that microplastics hosted specific bacterial assemblages distinct from surrounding environmental fractions, confirming their role as selective surfaces for microbial colonization.
Impact of microplastics on microbial diversity and pathogen distribution in aquaculture ecosystems: A seasonal analysis
Researchers studied bacteria growing on microplastics in fish farming waters and found that in summer, these plastic-attached communities became more connected and harbored several disease-causing species including Vibrio. Microplastics in aquaculture act as floating habitats for harmful bacteria, and seasonal warming makes this worse, raising concerns about seafood safety and the spread of infections to humans.
