ClearIngested Microplastics Can Act as Microbial Vectors of Ichthyofauna
Nylon strips ingested and excreted by wild fish were found to harbor adherent microbiota including potential pathogens, demonstrating that microplastics can vector microorganisms through fish gut passage and into aquatic environments.
Analisis Mikroplastik Pada Saluran Pencernaan Ikan Kembung (Rastrelliger Sp.) di Pelabuhan Perikanan Samudera Belawan, Sumatera Utara
Indonesian researchers analyzed microplastics in the digestive tracts of mackerel fish landed at Belawan fishing port, examining both the characteristics of particles and their relationship to fish size. The presence of microplastics in commercially important fish species represents a direct pathway for human dietary exposure.
Characteristics of microplastic pollution in golden pompano (Trachinotus ovatus) aquaculture areas and the relationship between colonized-microbiota on microplastics and intestinal microflora
Researchers found that microplastics in golden pompano aquaculture areas colonize with distinct microbial communities that overlap with the fish's gut microbiota, increasing Proteobacteria and decreasing Firmicutes in the intestinal flora of fish living in more contaminated estuarine settings.
Understanding the links between micro/nanoplastics-induced gut microbes dysbiosis and potential diseases in fish: A review
This review examines how microplastics and nanoplastics accumulate in fish intestines and disrupt their gut bacteria, potentially leading to inflammation, immune problems, and metabolic diseases. The disrupted gut microbiome can weaken the intestinal barrier, allowing harmful substances to enter the fish's body. Since fish are a major protein source for billions of people, understanding how microplastics damage fish gut health is important for assessing risks to human food safety.
Ingested Microplastics Act as Microbial Vectors
Researchers investigated whether ingested microplastics act as vectors for pathogenic microorganisms by exposing wild fish to 4 mm nylon strips and analysing bacterial communities on strips retrieved after excretion. They found that both ingested strips and water-submerged controls harboured large numbers of pathogens including known pathogenic strains, demonstrating that nylon microplastics can transport and potentially amplify microbial communities including pathogens within fish digestive systems.
Microplastic abundance in commercially important brackish water fin-fish from the Bay of Bengal
Researchers analyzed the gastrointestinal tracts of seven commercially important fish species from the Bay of Bengal, confirming widespread microplastic contamination dominated by fibers and fragments, with implications for seafood safety.
Effects of microplastics on trophic parameters, abundance and metabolic activities of seawater and fish gut bacteria in mesocosm conditions
Mesocosm experiments showed that microplastics altered bacterial community structure and metabolic activity in both seawater and fish guts, suggesting that plastic pollution can disrupt microbial ecosystems in the marine environment. The findings raise concerns about how microplastic-driven microbiome changes could affect fish health and broader ecosystem functioning.
Plastics in our water: Fish microbiomes at risk?
This review examined how microplastics and leached plasticizers affect the gut microbiomes of freshwater and marine fish, summarizing evidence for dysbiosis and reduced microbial diversity and discussing potential consequences for fish immunity, metabolism, and environmental fitness.
Novel Autochthonous Strains from Cyprinus carpio as Candidates for Probiotic Use and Microplastic-Degrading Properties
Researchers isolated six bacterial genera from the gut of common carp (Cyprinus carpio) and identified two novel Hafnia strains with both probiotic potential and microplastic-degrading properties, suggesting a dual role for gut bacteria in fish health and environmental bioremediation.
Investigation of microplastic contamination in the gastrointestinal tract of some species of caught fish from Oman Sea
Researchers found microplastics in the gastrointestinal tracts of fish species sampled from marine environments, documenting plastic ingestion across multiple species. The study contributes to the growing evidence base on microplastic contamination in commercially important fish.
The Presence of Microplastics in the Gills and Gastrointestinal Tract of Mackerel (Rastrelliger Kanagurta Cuvier, 1816) from Jakarta Bay, Indonesia
Researchers examined microplastic contamination in the gills and gastrointestinal tracts of 120 mackerel (Rastrelliger kanagurta) from Jakarta Bay, Indonesia, characterizing particle types, sizes, and colors. All fish contained microplastics, with fragments being most prevalent followed by fibers and films, particles smaller than 0.1 mm and black-colored particles dominating both tissues, and no significant difference in microplastic abundance between sampling locations.
Antibiotic resistance of bacteria isolated from Pagellus erythrinus microplastics and public health
Researchers examined microplastics found in the gastrointestinal tract and gills of a commercial Mediterranean fish (Pagellus erythrinus) and found bacteria with antibiotic resistance genes attached to the plastic surfaces. The findings suggest microplastics may serve as a vector for spreading antibiotic-resistant bacteria through the food chain when humans consume contaminated seafood.
Occurrence of microplastics in commercial fish from a natural estuarine environment
Researchers examined the gastrointestinal tracts of commercial fish caught from a natural estuarine environment and found microplastics in a significant proportion of individuals, documenting both occurrence rates and particle characteristics.
Microplastic Contamination in Indian Mackerel (Rastrelliger kanagurta) and Finletted Mackerel (Megalaspis cordyla): Exploring Occurrence and Variability in Skin and Gill Tissues
Researchers collected Indian mackerel and finletted mackerel from a Kerala fish market and used light microscopy to identify microplastics including films, fibres, fragments, and lines in skin and gill tissues, finding higher concentrations in skin than gills for Rastrelliger kanagurta.
Comparison of Presence of Microplastics in Two Edible Fish Species from South India
Researchers compared microplastic contamination in two edible fish species from South India, finding differences in the abundance and types of microplastics between species that likely reflect differences in feeding habits and habitat use.
Occurrence of microplastics in gastrointestinal tracts of planktivorous fish from the Thoothukudi region
Planktivorous fish from the Thoothukudi region of southern India were surveyed for microplastic ingestion, with plastics found in a high proportion of the 677 individuals examined across multiple species. The results demonstrate that passive ingestion during filter feeding makes planktivorous fish particularly susceptible to microplastic exposure.
The pervasiveness of microplastic contamination in the gastrointestinal tract of fish from the western coast of Bangladesh
Researchers found microplastics in every individual fish examined from the western coast of Bangladesh, with an average of 7.1 particles per specimen, and demersal species accumulating more microplastics than pelagic species near the world's largest mangrove ecosystem.
Polystyrene microplastics interaction and influence on the growth kinetics and metabolism of tilapia gut probiotic Bacillus tropicus ACS1
Polystyrene microplastics were found to alter the gut microbiome of tilapia, disrupting the growth kinetics and metabolism of probiotic bacteria, with potential implications for fish health and aquaculture productivity.
Polystyrene microplastics induce gut microbiome and metabolome changes in Javanese medaka fish (Oryzias javanicus Bleeker, 1854)
Researchers found that polystyrene microplastic exposure altered gut microbiome composition and metabolic profiles in Javanese medaka fish, with effects on amino acid and lipid metabolism pathways suggesting microplastics can disrupt gut health in aquatic organisms.
Microplastics (MPs) accumulation in two edible marine fish species sourced from the Bay of Bengal: Contamination level and risk assessment
Researchers measured microplastic contamination in two commonly eaten fish species from the Bay of Bengal, examining both gills and digestive tracts. Microplastics were found in all fish studied, with differences in accumulation based on the species' feeding habits and where they live in the water column. Since these fish are widely consumed by local populations, the findings raise concerns about human microplastic intake through seafood.
