ClearInvestigating Biofilms: Advanced Methods for Comprehending Microbial Behavior and Antibiotic Resistance
This review summarizes recent advances in biofilm research, focusing on how communities of microorganisms form protective layers on surfaces and become resistant to antibiotics. The sticky matrix that holds biofilms together plays a key role in spreading antibiotic resistance genes between bacteria. While not directly about microplastics, the findings are relevant because microplastics in the environment serve as surfaces where these resistant biofilms can form and spread.
Growth and prevalence of antibiotic-resistant bacteria in microplastic biofilm from wastewater treatment plant effluents
Researchers studied antibiotic-resistant bacteria growing in biofilms on microplastic surfaces in wastewater treatment plant effluent. The study found that microplastic biofilms accumulated antibiotic-resistant bacteria including Pseudomonas, Aeromonas, and Bacillus, and that these biofilms harbored higher concentrations of resistance genes compared to surrounding water, suggesting microplastics may serve as reservoirs for antibiotic resistance.

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.
Biofilm formation on microplastics and interactions with antibiotics, antibiotic resistance genes and pathogens in aquatic environment
This review explains how microplastics in waterways develop bacterial biofilms on their surfaces that can harbor antibiotic-resistant bacteria and help spread antibiotic resistance genes to new environments. This is concerning for human health because these resistant microbes could eventually reach people through drinking water or seafood consumption.
Detection of virulence genes in bacteria associated with microplastics from selected Rivers in Ado-Ekiti, Nigeria
Researchers investigated virulence genes in bacteria associated with microplastics collected from five rivers in Ado-Ekiti, Nigeria over a 24-month biweekly sampling program, isolating 16 bacterial species including Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, and Staphylococcus aureus. The study characterized antibiotic susceptibility patterns and virulence gene profiles of these microplastic-associated bacteria, highlighting the role of microplastics as vectors for pathogenic and antibiotic-resistant organisms in Nigerian freshwater systems.
Effects of microplastic concentration, composition, and size on Escherichia coli biofilm-associated antimicrobial resistance
This study examined how different types of microplastics affect the development of antibiotic-resistant bacteria through biofilm formation. The researchers found that the concentration, composition, and size of microplastic particles all influence how effectively bacteria like E. coli develop drug resistance. These findings are important because they help explain how widespread plastic pollution may be contributing to the growing global crisis of antibiotic resistance.
Understanding How Staphylococcal Autolysin Domains Interact With Polystyrene Surfaces
Researchers studied how a protein from Staphylococcus bacteria—which causes healthcare-associated infections—binds to polystyrene plastic surfaces, contributing to biofilm formation on medical devices. Understanding this interaction could help develop strategies to prevent dangerous bacterial biofilms on plastic medical equipment.
Microplastics as emerging reservoirs of antimicrobial resistance: Clinical relevance and environmental mechanisms
This review examines how microplastics act as environmental reservoirs for antibiotic resistance genes, creating selective microenvironments through antibiotic and metal adsorption, biofilm formation, and horizontal gene transfer, with potential pathways to clinical human exposure.
Characterization and tolerance of foodborne pathogenic bacteria in microplastic biofilm
Three foodborne pathogens -- Salmonella, Staphylococcus aureus, and Listeria -- were shown to form biofilms on microplastic surfaces within two days, with smaller particles supporting more biofilm growth and Salmonella showing partial resistance to sodium hypochlorite disinfection even at 50 ppm.
Biofilm Formation of Clinically Important Bacteria on Bio-Based and Conventional Micro/Submicron-Sized Plastics.
This study compared how clinically important bacteria form biofilms on bio-based versus conventional plastic surfaces of similar size, finding differences in biofilm formation patterns between bioplastics and their conventional equivalents. The results suggest that the push to replace conventional plastics with bioplastics should consider how these materials interact with potentially harmful bacteria.
