ClearResponses of Free-Living Vibrio Community to Seasonal Environmental Variation in a Subtropical Inland Bay
Researchers used Vibrio-specific 16S rRNA sequencing to characterize seasonal distribution and diversity of free-living Vibrio communities in the Maowei Sea, finding that Shannon diversity peaked in summer while community composition shifted with temperature and nutrient availability, revealing how seasonal eutrophication shapes the dynamics of this pathogen-relevant bacterial genus.
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.

Improving environmental monitoring of Vibrionaceae in coastal ecosystems through 16S rRNA gene amplicon sequencing
Researchers used genetic sequencing of bacterial 16S rRNA genes to track Vibrionaceae — a family of bacteria that includes several species harmful to fish, shellfish, and humans — in the northern Adriatic Sea over multiple years. They found that blooms of certain Vibrio species occurred in summer linked to warming water temperatures, while pathogenic species remained at low but detectable levels throughout the monitoring period.

Exploring the Microdiversity Within Marine Bacterial Taxa: Toward an Integrated Biogeography in the Southern Ocean
Researchers used advanced sequencing techniques to study the fine-scale diversity and geographic distribution of bacteria in the Southern Ocean. Understanding ocean microbial communities is relevant to microplastic research because plastics in the ocean host distinct microbial communities that can alter local ecology.
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.
The gut microbial of sea urchin ( Strongylocentrotus intermedius ) under different temperatures: Microbial structure and co-occurrence patterns
Researchers exposed sea urchins to five temperatures ranging from 13 to 25°C and used high-throughput sequencing to show that elevated temperatures increase gut bacterial diversity, shift dominant genera, alter key metabolic pathways, and strengthen deterministic assembly processes, providing mechanistic insight into how warming reshapes invertebrate gut microbiomes.
Machine learning to predict dynamic changes of pathogenic Vibrio spp. abundance on microplastics in marine environment
Researchers developed machine learning models to predict dynamic changes in pathogenic Vibrio bacteria abundance on microplastics in marine environments, finding that environmental factors like temperature and salinity significantly influence pathogen colonization on plastic surfaces.
It’s time to act: Understanding and combating Vibrio vulnificus
This review examines Vibrio vulnificus, a dangerous marine bacterium that can cause life-threatening infections with mortality rates exceeding 50% in vulnerable individuals. Researchers highlight that climate warming has doubled the geographic range and infection risk of this pathogen, while microplastic pollution and extreme weather events further enhance its ecological adaptability and survival.
Distinctive signatures of pathogenic and antibiotic resistant potentials in the hadal microbiome
Researchers mapped antibiotic resistance genes and disease-causing microbial traits in the deepest parts of the ocean — the Mariana Trench — revealing a unique and largely unknown landscape of microbial risk factors even in Earth's most remote environments.
Vibrio spp and other potential pathogenic bacteria associated to microfibers in the North-Western Mediterranean Sea
Researchers found that floating microfibers in the northwestern Mediterranean Sea harbor diverse bacterial communities including potential pathogens like Vibrio species, demonstrating that microfibers serve as vectors for harmful bacteria in marine environments.
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.
High diversity of Vibrio spp. associated with different ecological niches in a marine aquaria system and description of Vibrio aquimaris sp. nov
Researchers cultured Vibrio bacteria from multiple niches within a marine aquarium — including microplastic particles, sediment, detritus, and water — and found that microplastics hosted lower Vibrio diversity than water or detritus, while also identifying a novel Vibrio species (Vibrio aquimaris sp. nov.) from the plastic-associated isolates.
First Steps towards a near Real-Time Modelling System of Vibrio vulnificus in the Baltic Sea
Researchers developed initial steps toward a near real-time modeling system for Vibrio vulnificus in the Baltic Sea, testing hydrodynamic and biogeochemical model data as inputs to predict pathogen concentrations along the German coast.
Eco-evolutionary Dynamics Linked to Horizontal Gene Transfer in Vibrios
This review examines the ecology and genomic plasticity of Vibrio bacteria in aquatic environments, focusing on how horizontal gene transfer (HGT) drives adaptation to new niches and the emergence of pathogenic strains. Researchers discuss HGT mechanisms across environmental and clinical vibrio isolates and the role of mobile virulence factors in shaping pathogen evolution.
Influence of host phylogeny and water physicochemistry on microbial assemblages of the fish skin microbiome
Researchers conducted a large-scale analysis of nearly 2,000 fish skin microbiome samples across 98 species to understand what factors shape microbial communities on fish surfaces. They found that host evolutionary history and water chemistry, particularly salinity and temperature, were the strongest predictors of skin microbiome composition. The study provides a broad framework for understanding how environmental stressors, including pollutants, may disrupt the beneficial microbial communities on fish.
Latitudinal Diversity Gradients (LDGs) and macroalgal microbiomes: A chimera of biotic and abiotic effects?
This commentary discusses a study examining how the microbiomes of the brown seaweed Fucus vesiculosus vary across latitude on both sides of the Atlantic Ocean, finding that geography and temperature influence microbial community composition more than host genetic factors. Understanding how environmental gradients shape marine microbiomes is relevant to assessing how pollution stressors like microplastics may alter these communities.
The Extent and Pattern of Mariculture Impacts on Spatial and Seasonal Variations of Sediment Bacterial Communities Among Three Coastal Waters
Researchers used high-throughput sequencing to examine spatial and seasonal variations in sediment bacterial communities across three Chinese coastal bays with large-scale suspended mariculture, finding that spatial variation was a stronger driver of community composition than seasonality, with Proteobacteria, Bacteroidetes, and Planctomycetes dominating across all sites and mariculture-associated organic loading shaping local community structure.
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.
