Summary: Previous studies focused on direct interactions of plastics with microorganisms, but ignored their ecotoxicity effects on the dissemination of antibiotic resistance genes (ARGs). This study reveals that environmentally relevant concentrations of phthalates (PAEs) significantly enhance the transfer of ARGs among environmental microorganisms. The interaction between PAEs and cell membrane phospholipids lowers membrane fluidity and increases permeability, facilitating gene transfer. Increased levels of reactive oxygen species and overexpression of conjugation-associated genes under PAE stress also contribute to enhanced gene transfer. This study provides important insights into the environmental risks of plastics and the control of ARG spreading.

Summary: Marine microplastic pollution is a pressing issue in ecotoxicology. Microplastics can harbor pathogenic microorganisms and are colonized by various types of microbes, forming a biofilm known as the plastisphere. The microbial community in the plastisphere differs from surrounding environments and plays a role in plastic degradation. Factors like environmental conditions and polymers influence the composition of the plastisphere. Quorum sensing has the potential to be a new research area to understand and promote microplastics degradation in the ocean.

Summary: This study explored the impact of polystyrene particles with different sizes on the horizontal gene transfer of antibiotic resistance genes (ARGs) mediated by plasmids into Escherichia coli cells. The results showed that small particles had an effect on the transfer of ARGs, while large particles did not. The effects of particles on plasmid transfer varied depending on the plasmid's replication capacity. The mechanisms involved direct interaction with membrane lipids and interference with plasmid replication. This study contributes to our understanding of the environmental dissemination of ARGs in plastic contamination.

Summary: Microplastic biofilms in aquatic environments have become hotspots for antibiotic resistance genes, influenced by exogenous pressures. The dynamic evolution of ARGs, intI1, MRGs, and bacterial communities in MP and NS biofilms are significantly impacted by individual and combined pressures, resulting in noticeable differences between the two substrates.

Summary: This study systematically investigated the effects of microplastic aging on bacterial horizontal gene transfer. The results showed that aging increased the efficiency of antibiotic resistance gene transfer from microplastics to recipient bacteria, possibly due to increased specific surface area and affinity for the gene vectors. Additionally, aged microplastics released more organic compounds, induced ROS generation, increased cell permeability, and upregulated genes associated with gene transfer. The findings highlight the significance of microplastic aging in the environmental dissemination of antibiotic resistance and other gene transfer processes.

Summary: This study explores the factors influencing biofilm formation on microplastic surfaces and finds that density and surface characteristics of microplastics are key factors. Biofilm formation on plastics with similar density to water shows significant differences based on surface characteristics, while biofilm formation on plastics with higher density is heavily influenced by particle movement.

Summary: The study found that antibiotic resistance genes enriched on microplastics were more abundant than on inorganic substrates and natural water environments, but less abundant than on natural organic substrates. Microplastics in freshwater tended to have a higher degree of ARG enrichment than those in saline water and sewage.

Summary: Triclosan significantly enhances the conjugative transfer of the RP4 plasmid among activated sludge communities, promoting both intergenera and intragenera transfer. Triclosan also facilitates the transfer of the RP4 plasmid to opportunistic human pathogens. The mechanism behind triclosan-mediated conjugative transfer involves oxidative stress, increased membrane permeability, and the activation of the SOS response.

Summary: In recent years, there has been a growing awareness of the environmental hazards posed by plastic debris and the role of the environment in spreading antibiotic resistant bacteria. Microplastic particles can serve as a novel ecological niche, facilitating the survival of pathogens and antibiotic resistant bacteria. The formation of the plastisphere can significantly influence the overall microbiome of a specific habitat.

Summary: The study found that commonly used nonnutritive sweeteners may enhance plasmid-mediated conjugative transfer between bacteria, increasing the spread of antibiotic resistance genes. Bacteria exposed to these compounds produced more reactive oxygen species, triggered the SOS response, and experienced increased cell membrane permeability.

Summary: This review discusses the ecological effects of microplastics and antibiotic resistance genes in aquaculture environments. The widespread use of antibiotics in agricultural production leads to the presence of antibiotic residues in water and the emergence of antibiotic-resistant bacteria. Additionally, water microplastics act as carriers of environmental microbes and antibiotic-resistant bacteria, potentially entering aquaculture environments and eventually the human body through food chains.
