ClearExposing Salmonella Senftenberg and Escherichia coli Strains Isolated from Poultry Farms to Formaldehyde and Lingonberry Extract at Low Concentrations
This paper is not relevant to microplastics research — it investigates the antibiotic resistance and biofilm-forming ability of Salmonella and E. coli bacteria isolated from poultry feed.
Characteristics of microplastics in typical poultry farms and the association of environment microplastics colonized-microbiota, waterfowl gut microbiota, and antibiotic resistance genes
Researchers investigated microplastic contamination in poultry farm environments and in the intestines of farm-raised waterfowl for the first time. They found microplastics in soil, pond water, and bird guts, with the plastic surfaces hosting microbial communities that carried antibiotic resistance genes. This raises dual concerns: microplastics may both contaminate poultry meat that humans eat and help spread antibiotic-resistant bacteria through farming environments.
Biofilm–microplastic interactions in food safety: mechanisms, risks, and control strategies
This review investigates how microplastics in the food industry serve as surfaces where bacterial biofilms can form, creating complexes that resist cleaning and disinfection. Researchers found that these biofilm-microplastic combinations can shield harmful bacteria and promote the spread of antibiotic-resistance genes. The study evaluates strategies for preventing and controlling this form of contamination in food systems.
Formation of biofilms on microplastics in the food chain and their role as vectors of transfer of foodborne pathogens (literature review, part 2)
This literature review (Part 2 of a series) examines how biofilms formed on micro- and nanoplastic surfaces in the food chain can serve as vectors for pathogenic bacteria, their toxins, and antibiotic resistance genes — potentially increasing foodborne disease risk beyond what bare microplastic particles would cause.
Harmful impacts of microplastic pollution on poultry and biodegradation techniques using microorganisms for consumer health protection: A review
This review examines how microplastic pollution affects poultry health and food safety, finding that microplastics have been detected in chicken meat from supermarkets and open markets. Evidence indicates that microplastics can damage vital organs in poultry, reduce egg production, and accumulate in edible tissues. The authors also review biodegradation techniques using microorganisms as a potential strategy for reducing microplastic contamination in the food supply.
The Occurrence of Microplastics and the Formation of Biofilms by Pathogenic and Opportunistic Bacteria as Threats in Aquaculture
This review examines how microplastics in aquaculture environments serve as habitats and transport vehicles for pathogenic and opportunistic bacteria, with more than 30 taxa of pathogens detected on plastic-associated biofilms. The study suggests that the combination of plastic persistence, closed aquaculture conditions, and pathogen affinity for plastic surfaces creates a significant threat to aquaculture production and food safety.
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.
Characteristics of Initial Attachment and Biofilm Formation of Pseudomonas aeruginosa on Microplastic Surfaces
Researchers characterized how Pseudomonas aeruginosa initially attaches to and forms biofilms on different microplastic surfaces, finding that polymer type and surface properties significantly influenced bacterial colonization patterns and biofilm development.
Prototype for rapid test devices to detect residues of sulfonamides in chicken carcasses from traditional breeders in Surabaya, Indonesia
This paper is not about microplastics; it describes rapid test devices for detecting sulfonamide antibiotic residues in chicken carcasses.
Imperative implication of microplastics as vital agent for salmonellosis inducing biofilms, antibiotic resistance, and health risk
This review examines how microplastics serve as reservoirs and vectors for Salmonella, promoting biofilm formation, environmental persistence, and the spread of antibiotic resistance. Researchers summarized evidence that weathered, hydrophobic microplastic surfaces create stable microhabitats that enhance bacterial adhesion and virulence. The findings suggest that microplastics may play a significant role in amplifying foodborne disease risks and accelerating the evolution of drug-resistant pathogens.
Investigating 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.
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.
Molecular mechanisms of heavy metal resistance and cross-/co-resistance to antibiotics in Pseudomonas aeruginosa
This review examines how the harmful bacterium Pseudomonas aeruginosa develops resistance to both heavy metals and antibiotics through shared defense mechanisms, and how microplastics make the problem worse by carrying both pollutants together. When bacteria encounter microplastics loaded with heavy metals and antibiotics, they can develop resistance to multiple threats at once. This is concerning for human health because it could make infections harder to treat with existing antibiotics.
A critical review of microbiological colonisation of nano- and microplastics (NMP) and their significance to the food chain
This review examined how nano- and microplastics become colonized by diverse microbial communities in aquatic and terrestrial environments, highlighting how these 'plastisphere' biofilms may harbor pathogens and facilitate the spread of antibiotic resistance genes through the food chain.
A review focusing on mechanisms and ecological risks of enrichment and propagation of antibiotic resistance genes and mobile genetic elements by microplastic biofilms
This review examines how microplastics in water serve as surfaces for bacterial biofilms that harbor antibiotic resistance genes. The biofilms that form on microplastic surfaces can spread resistance genes to other bacteria and potentially to organisms that ingest them, including fish and ultimately humans. The authors highlight that microplastic-associated antibiotic resistance is an underappreciated public health risk that needs more research.
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.
Insights into the Microbiological Safety of Wooden Cutting Boards Used for Meat Processing in Hong Kong’s Wet Markets: A Focus on Food-Contact Surfaces, Cross-Contamination and the Efficacy of Traditional Hygiene Practices
Wooden cutting boards used for meat processing in Hong Kong wet markets were colonized by potentially pathogenic microorganisms, and traditional cleaning practices failed to prevent cross-contamination of meat processed on previously used boards. Several bacteria with biofilm-forming abilities were identified, raising public health concerns about hygiene standards in traditional fresh meat markets.
An Assessment of the Current Trends of Antibiotic Resistance of Salmonella Typhi Against 1st Line Antimicrobial Agents in Metropolitan City of Karachi
