ClearCo-selection of multi-antibiotic resistance in bacterial pathogens in metal and microplastic contaminated environments: An emerging health threat
This review explores how metals and microplastics in the environment can drive the development of antibiotic-resistant bacteria through a process called co-selection. Researchers found that heavy metals like mercury, lead, and zinc can trigger bacteria to develop resistance to multiple antibiotics simultaneously, and that microplastics serve as platforms where these resistant bacteria can proliferate. The study highlights an emerging health threat where environmental contamination with metals and plastics could accelerate the spread of antibiotic resistance to human pathogens.
The interplay between antimicrobial resistance, heavy metal pollution, and the role of microplastics
This review explores the three-way connection between microplastics, heavy metals, and antibiotic resistance in the environment. Microplastics serve as surfaces where bacteria form biofilms and exchange resistance genes, while heavy metals have been driving bacterial resistance for billions of years through similar genetic mechanisms. Together, these pollutants create hotspots where dangerous antibiotic-resistant bacteria can develop and spread.
Interactions and associated resistance development mechanisms between microplastics, antibiotics and heavy metals in the aquaculture environment
This review explores how microplastics, antibiotics, and heavy metals interact in aquaculture environments to promote antibiotic resistance. Researchers found that microplastics can serve as carriers for both antibiotics and metals, creating hotspots where bacteria are more likely to develop resistance genes. The study underscores the compounding ecological and human health risks when these three types of pollutants co-exist in fish farming settings.
Assessing microplastics-antibiotics coexistence induced ciprofloxacin-resistant Pseudomonas aeruginosa at a water region scale
This study found that microplastics in water can promote the development of antibiotic-resistant bacteria, specifically ciprofloxacin-resistant Pseudomonas aeruginosa, a dangerous human pathogen. Microplastics provide surfaces where bacteria colonize and exchange resistance genes, especially in water contaminated with both plastics and antibiotics. The findings suggest that microplastic pollution in waterways could contribute to the growing problem of antibiotic resistance, which threatens the effectiveness of medical treatments.
Microplastics and antibiotic resistance genes as rising threats: Their interaction represents an urgent environmental concern
This review examines how microplastics interact with antibiotics and antibiotic-resistant bacteria in the environment, creating a combined pollution threat. Microplastics can absorb antibiotics onto their surface and serve as platforms where bacteria exchange resistance genes. This interaction could accelerate the spread of antibiotic resistance, making infections harder to treat and posing a growing public health risk.
Do microplastic biofilms promote the evolution and co-selection of antibiotic and metal resistance genes and their associations with bacterial communities under antibiotic and metal pressures?
Researchers investigated whether microplastic biofilms promote the evolution and co-selection of antibiotic and metal resistance genes compared to natural substrates, examining how combined antibiotic and metal pressures shape resistant bacterial communities on plastic surfaces.
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 nexus of microplastics, food and antimicrobial resistance in the context of aquatic environment: Interdisciplinary linkages of pathways
This review examines how microplastics in aquatic environments serve as surfaces where bacteria can grow, share antibiotic resistance genes, and then enter the food chain through contaminated seafood. The combination of microplastic pollution and antimicrobial resistance creates a compounding threat, as resistant bacteria riding on plastic particles can survive water treatment and reach humans. The authors call for interdisciplinary research connecting environmental science and public health to address this growing risk.
Unveiling the Interactions Between the Antibiotic Resistome and Microplastics Influenced by Trace Elements and PPCPs in Wastewater Treatment Plants
Researchers monitored wastewater treatment plants containing microplastics, trace elements, and pharmaceutical/personal care products, finding that these co-occurring pollutants interact to influence the survival and spread of antibiotic-resistant bacteria and resistance genes through the treatment process.
A critical review of the adsorption-desorption characteristics of antibiotics on microplastics and their combined toxic effects
This systematic review examines how microplastics absorb and release antibiotics in the environment, and the combined toxic effects of this interaction. When microplastics carrying antibiotics are ingested by living organisms, they may promote antibiotic resistance and cause greater harm than either pollutant alone, which is a growing concern for human health.
Environmental drivers of antibiotic resistance: Synergistic effects of climate change, co-pollutants, and microplastics
This review examines how climate change, chemical pollutants, and microplastics work together to accelerate the spread of antibiotic resistance, a growing global health crisis. Microplastics provide surfaces where bacteria form communities that exchange resistance genes, and as these plastics age in the environment, they become even better at absorbing other pollutants, creating hotspots that amplify drug resistance.
Insight into combined pollution of antibiotics and microplastics in aquatic and soil environment: Environmental behavior, interaction mechanism and associated impact of resistant genes
This review examines the combined pollution created when microplastics absorb antibiotics in water and soil environments. Researchers found that microplastics can concentrate antibiotics on their surfaces, and this combination promotes the spread of antibiotic-resistant genes in microbial communities. The study highlights that the interaction between these two emerging pollutants may pose greater environmental and health risks than either one alone.
