ClearStudy of the impact of ocean warming on the expression of virulence factors in Vibrio parahaemolyticus and the response of the host Exaiptasia pallida to infection
Rising ocean temperatures are making the foodborne pathogen Vibrio parahaemolyticus more virulent, and this study shows that microplastics may be amplifying the threat by serving as surfaces on which these bacteria colonize and spread. Using a sea anemone model, the researchers explored how ocean warming and microplastic-associated pathogens together stress marine organisms. This is significant because microplastics acting as 'pathogen vectors' could increase the risk of seafood-borne illness for humans as ocean conditions change.
Potential impact of marine-derived plastisphere as a Vibrio carrier on marine ecosystems: Current status and future perspectives
This review examines how microplastics in the ocean serve as floating platforms for Vibrio bacteria, which are significant pathogens threatening aquaculture and marine ecosystem health. Researchers found that the so-called plastisphere, the microbial community that colonizes plastic surfaces, can enhance the survival and spread of these harmful bacteria. The study highlights a concerning link between plastic pollution and the potential amplification of waterborne disease risks.
Sources and contamination routes of seafood with human pathogenic Vibrio spp.: A Farm‐to‐Fork approach
This review examines how Vibrio bacteria, which cause food poisoning, contaminate seafood from farm to table, emphasizing the role of environmental factors like climate change and pollution. While not directly about microplastics, the research is relevant because microplastic surfaces in water can harbor and transport pathogenic bacteria like Vibrio. Understanding these contamination pathways is important for ensuring the safety of seafood that people consume.

Vibrio species can cause serious intestinal illness in humans through contaminated water or raw seafood consumption.
Public health aspects of Vibrio spp. related to the consumption of seafood in the EU
This scientific opinion reviews how Vibrio bacteria in seafood cause illness in the EU, finding that about one in five seafood samples carries potentially harmful strains. While not directly about microplastics, rising ocean temperatures linked to climate change are expected to increase Vibrio contamination in seafood, compounding concerns about the safety of marine food sources.
Tools to Enumerate and Predict Distribution Patterns of Environmental Vibrio vulnificus and Vibrio parahaemolyticus
This review synthesizes the current understanding of environmental factors driving the distribution of pathogenic Vibrio vulnificus and Vibrio parahaemolyticus in aquatic environments. The study highlights various tools used to enumerate these bacteria and examines predictive models that incorporate temperature, salinity, and other ecological drivers to forecast Vibrio distribution patterns.
Human Activity as a Growing Threat to Marine Ecosystems: Plastic and Temperature Effects on the Sponge Sarcotragus spinosulus
Researchers studied how plastic debris in the ocean acts as a surface for harmful Vibrio bacteria to grow on, and how rising water temperatures amplify stress on the marine sponge Sarcotragus spinosulus. The findings suggest that the combination of plastic pollution and warming seas creates compounding threats to marine organisms and the broader coastal ecosystem.
Assessing biofilm formation and resistance of vibrio parahaemolyticus on UV-aged microplastics in aquatic environments
Researchers found that UV-weathered microplastics in seawater promote more bacterial biofilm growth than fresh microplastics, and that the food-poisoning bacterium Vibrio parahaemolyticus becomes more resistant to common disinfection methods when growing on these aged plastics. Bacteria on the UV-aged microplastics showed increased resistance to chlorine, heat, and even the harsh conditions of the human stomach. This means that microplastics weathered by sunlight in the ocean could make seafood-borne pathogens harder to kill, increasing food safety risks.
Insight into the multifactorial effect of climate change on marine bacteria: resilience mechanisms and mitigation strategies
This review examines how multiple climate change factors — including ocean acidification, warming, deoxygenation, and anthropogenic pollutants including microplastics — interact to affect marine bacteria and their roles in biogeochemical cycling. The authors synthesize resilience mechanisms employed by marine bacteria and discuss mitigation strategies to preserve microbial ecosystem functions under accelerating environmental change.
Enrichment and dissemination of bacterial pathogens by microplastics in the aquatic environment
This review examines how microplastics serve as floating platforms for dangerous bacteria in waterways, harboring pathogens like Vibrio and Pseudomonas at higher densities than surrounding water. Researchers found that bacteria can transfer between microplastic surfaces and water through mechanisms like horizontal gene transfer and chemical signaling. The findings raise concerns that microplastic pollution may be accelerating the spread of waterborne pathogens that threaten both ecosystem and human health.
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.
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.
Vibrio Colonization Is Highly Dynamic in Early Microplastic-Associated Biofilms as Well as on Field-Collected Microplastics
Researchers found that Vibrio colonization on polyethylene and polystyrene microplastics is highly dynamic during the first 10 hours of biofilm formation, with Vibrio abundance and species composition varying irregularly both in laboratory incubations and on field-collected Baltic Sea microplastics, complicating assessments of microplastics as vectors for pathogenic bacteria.
