ClearLatitudinal Dynamics of Vibrio along the Eastern Coastline of Australia
Researchers mapped Vibrio bacterial abundance and diversity along 4000 km of Australia's eastern coastline using amplicon sequencing and quantitative PCR, finding that sea surface temperature was the strongest predictor of Vibrio community composition and pathogen abundance. Warmer northern waters harbored higher concentrations of pathogenic Vibrio species including V. cholerae and V. vulnificus.
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.
Bacterioplankton Community Structure and Its Relationship with Environmental Factors in the Coastal Waters Around the Changli Gold Coast National Nature Reserve in Northern China
Researchers investigated bacterioplankton community structure in coastal waters around a Chinese nature reserve, finding significant seasonal variability in nutrients and identifying key environmental drivers—including nitrogen, phosphorus, and carbon—of bacterial community composition.
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.
Urbanization promotes specific bacteria in freshwater microbiomes including potential pathogens
Researchers used full-length 16S rRNA sequencing to compare freshwater microbial communities across urban and rural lakes in Germany, finding that urbanization consistently promoted specific bacterial genera including potential pathogens such as Escherichia/Shigella and Rickettsia, driven by warming, eutrophication, and wastewater inputs.
Meteorological and Water Quality Factors Associated with Microbial Diversity in Coastal Water from Intensified Oyster Production Areas of Thailand
Researchers monitored bacterial pathogens and water quality in major oyster cultivation areas across Thailand, finding that fecal coliform levels and pathogen presence varied with meteorological and environmental factors, with implications for seafood safety and public health risk.
Exploring changes in microplastic-associated bacterial communities with time, location, and polymer type in Liusha Bay, China
Researchers tracked how bacterial communities colonizing different types of microplastics changed over time in an aquaculture bay in China. They found that both exposure duration and plastic type significantly influenced which bacteria grew on the surfaces, with hydrocarbon-degrading species becoming notably abundant. Concerning from a health perspective, the pathogenic bacterium Vibrio was detected on all microplastic samples, suggesting that floating plastics may serve as rafts for disease-causing organisms.
Seasonal Dynamics of Marine Bacterial Communities in Aquaculture Farms: The case of the Northern Ionian Coastal Ecosystem (Mediterranean Sea)
Researchers characterized seasonal bacterial community dynamics across three Greek aquaculture farms in the Mediterranean, finding lower microbial diversity at farm sites compared to controls, with season being the primary driver of community composition changes.
Spatiotemporal changes of bacterial communities during a cyanobacterial bloom in a subtropical water source reservoir ecosystem in China
Researchers used DNA sequencing to track how bacterial communities in a Chinese reservoir changed during different phases of a cyanobacterial (harmful algae) bloom, finding that bacterial diversity dropped significantly during the bloom outbreak and that the composition of communities shifted in distinct ways tied to nutrient levels and temperature. Understanding these microbial dynamics could help water managers predict and control harmful algal blooms that threaten drinking water quality.
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.
The Right Place at the Right Time: Seasonal Variation of Bacterial Communities in Arid Avicennia marina Soils in the Red Sea Is Specific to Its Position in the Intertidal
Researchers investigated seasonal and spatial variation in bacterial community composition in the soils of an arid Avicennia marina mangrove ecosystem in the Red Sea, finding that microbial communities shifted significantly between seasons and intertidal positions. Summer shrub-site communities differed most markedly from fringe and winter communities, with environmental factors driven by seasonal sea level fluctuations controlling alpha diversity patterns.
Prokaryotic Responses to Estuarine Coalescence Contribute to Planktonic Community Assembly in a Mediterranean Nutrient-Rich Estuary
Researchers examined how prokaryotic community responses to the coalescence of freshwater and seawater communities in a Mediterranean nutrient-rich estuary contribute to planktonic community assembly, evaluating the respective roles of physical blending and microbial dynamics along a surface salinity gradient.
