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.
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.

Pathogenic Bacteria In Aquatic Ecosystems: Threats And Mitigation Approaches
This review examined pathogenic bacteria in aquatic ecosystems — including cholera, dysentery, and typhoid pathogens — and assessed the threats they pose to public health globally, particularly in regions with inadequate sanitation, alongside potential mitigation strategies.
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.
Environmental Reservoirs of Vibrio cholerae: Challenges and Opportunities for Ocean-Color Remote Sensing
This review examines how ocean color remote sensing can detect environmental conditions that favor Vibrio cholerae growth and survival in coastal waters, improving surveillance for cholera outbreaks. The work connects marine environmental monitoring to public health, relevant to understanding how ocean pollution and climate change affect waterborne disease risks.
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.
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.
Campylobacter—an Emerging Pollutant of Aquatic Environments
This review explores the growing presence of Campylobacter bacteria in aquatic environments worldwide, driven by factors including agricultural runoff, wastewater discharge, and climate change. Researchers highlight the public health risks posed by these bacteria and their antibiotic resistance genes in recreational and drinking water sources. The study calls for comprehensive monitoring and management strategies to address this emerging waterborne pollution concern.
Meteorological and Water Quality Factors Associated with Microbial Diversity in Coastal Water from Intensified Oyster Production Areas of Thailand

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.
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.
Vibrio Colonization Is Highly Dynamic in Early Microplastic-Associated Biofilms as Well as on Field-Collected Microplastics

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.
