ClearPolyvinyl chloride microplastics facilitated the transmission of Vibrio parahaemolyticus from surrounding water to Litopenaeus vannamei
Researchers investigated how PVC microplastics colonized by a harmful bacterium called Vibrio parahaemolyticus affect farmed shrimp. They found that the microplastics facilitated the transfer of the pathogen from the surrounding water into the shrimp, causing severe damage to the hepatopancreas and 100% mortality within 96 hours. The study reveals that microplastics in aquaculture environments can act as vehicles for disease-causing bacteria, posing serious risks to shrimp farming.
Role of microplastics in mediating the transmission of antibiotic resistance gene tet from antibiotic-resistant bacteria to Litopenaeus vannamei
Researchers investigated whether microplastics can carry antibiotic-resistant bacteria into shrimp (Litopenaeus vannamei), facilitating the transfer of resistance genes. They found that PVC microplastics carrying tetracycline-resistant bacteria altered the distribution of the resistance gene tet in shrimp tissues and caused changes in tissue structure and gene expression, suggesting microplastics may pose indirect risks to food safety.
Buoyant polyethylene rope fragments may enhance pathogenic bacteria dispersion in aquaculture water
Researchers examined how pathogenic bacteria colonize polyethylene rope fragments preconditioned with biofilms in marine aquaculture systems. The study found that Vibrio parahaemolyticus, Vibrio harveyi, Vibrio alginolyticus, and Pseudomonas plecoglossicida readily colonized the microplastic surfaces and expressed virulence genes, suggesting that buoyant rope fragments may enhance pathogen dispersal in aquaculture waters.
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.

A preliminary study of the association between colonization of microorganism on microplastics and intestinal microbiota in shrimp under natural conditions
Microplastics were detected in shrimp pond sediment (5,129 ± 1,176 items/kg) and in Litopenaeus vannamei shrimp tissue (14.08 ± 5.70 items/g), with MP abundance positively correlated between sediments and shrimp, and the microbiome on plastic surfaces differing from the shrimps' intestinal microbiota.
Analysis of Microplastic Contamination in Vaname Shrimp (Litopenaeus Vannamei) with Different Cultivation Methods
Researchers analyzed microplastic contamination across three different vaname shrimp (Litopenaeus vannamei) cultivation methods, sampling water, sediment, commercial feed, and shrimp tissues over three months. The study aimed to identify which cultivation system introduces more microplastics into the production environment and assess potential contamination routes for farmed shrimp.
The Effect of Microplastic Ingestion on Survival of the Grass Shrimp Palaemonetes pugio (Holthuis, 1949) Challenged with Vibrio campbellii
Grass shrimp (Palaemonetes pugio) that had ingested microplastics showed increased mortality when subsequently challenged with the marine pathogen Vibrio campbellii compared to shrimp that had not ingested plastics. This finding suggests that microplastic ingestion can compromise immune defenses in marine crustaceans, making them more vulnerable to bacterial infections.
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.
Bacterial community succession and the enrichment of antibiotic resistance genes on microplastics in an oyster farm
Researchers placed different types of microplastics in an oyster farm for 30 days and found that the plastics quickly became coated with bacteria, including antibiotic-resistant strains and potential human pathogens. The bacterial communities on plastic surfaces were distinct from those in the surrounding water and varied by plastic type. This means microplastics in seafood farming areas could serve as vehicles for spreading dangerous bacteria to humans through the food chain.
Plastics and Microplastics as Vectors for Bacteria and Human Pathogens
This study reviewed how marine plastic debris serves as a surface for bacterial colonization, including human pathogens, and examined the novel communities forming on plastic surfaces. The research raises public health concerns about microplastics acting as rafts that transport harmful bacteria to new locations, including to seafood and coastal recreational areas.

Researchers isolated and analyzed microplastics from vaname shrimp (Litopenaeus vannamei) collected at Tanjung Luar fish landing base in East Lombok, Indonesia. Microplastics were detected in shrimp digestive systems, raising food safety concerns given the direct pathway to human consumption through seafood.
Study 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.

Researchers conducted an in situ incubation experiment in a mariculture cage and found that polyethylene terephthalate, polyethylene, and polypropylene microplastics accumulated distinct bacterial pathogen communities during summer and autumn. The findings indicate that microplastics in aquaculture environments can act as reservoirs for potential pathogens, raising concerns for seafood safety.
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.
Combined Vibrio and nanoplastics stress promotes nanoplastic accumulation while reducing bacterial lethality in shrimp
Researchers discovered that Vibrio bacteria act as carriers for nanoplastics in shrimp, ferrying the tiny particles through the gut wall and concentrating them in organs, but interestingly the nanoplastics also weakened the bacteria's ability to cause infection, showing that plastic-pathogen interactions in seafood are complex and two-directional.
Impact of mariculture-derived microplastics on bacterial biofilm formation and their potential threat to mariculture: A case in situ study on the Sungo Bay, China
Scientists examined biofilm colonization on mariculture-derived microplastics (fishing nets, foams, floats) in Sanggou Bay, China over 21 days and found distinct microbial communities including potential fish pathogens and antibiotic resistance genes, raising concerns for mariculture safety.
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.
Microplastic study on (litopenaeus vannamei) cultivation enterprises on the east coast of aceh
Researchers sampled vannamei shrimp (Litopenaeus vannamei) from three cultivation stations on Aceh's east coast (Pidie, Pidie Jaya, and Bireuen) and analyzed microplastic content using H2O2/H2SO4 digestion and microscopy at 40x magnification. They found fiber and film microplastics in all shrimp samples, with the highest count (13 particles) at the Pidie station, indicating microplastic contamination has entered commercial aquaculture supply chains.
