Abstract Due to climate change the pathogenic bacterium Vibrio vulnificus proliferates along brackish coastlines, posing risks public health, tourism, and aquaculture. Here we investigated previously suggested regulation measures reduce prevalence of V. , locally through seagrass regionally reduction eutrophication consequential formation algal blooms. Field samples collected in summer 2021 covered salinity gradients Baltic Sea, one largest areas worldwide. Physico-, biological- hydrochemical parameters were measured variables explaining occurrence identified by machine learning. The best predictors eutrophication-related features, such as particulate organic carbon nitrogen, well potential phytoplankton blooms associated species . abundance did not vary significantly between vegetated non-vegetated areas. Thus, reducing nutrient inputs could be an effective method control populations eutrophied coasts.

ABSTRACT Changing climatic conditions influence parameters associated with the growth of pathogenic Vibrio spp. in environment and, hence, are linked to increased incidence vibriosis. Between 1992 and 2022, a long-term increase infections was reported Florida, USA. Furthermore, spike post Hurricane Ian, category five storm that made landfall Florida on 28 September 2022. During October water oyster samples were collected from three stations Lee County an area significantly impacted by Ian. isolated, whole-genome sequencing phylogenetic analysis done, focus parahaemolyticus vulnificus provide genetic insight into strains circulating environment. Metagenomic provided respect human health-related factors, notably detection approximately 12 spp., virulence antibiotic resistance genes, mobile elements, including SXT/R391 family integrative conjugative elements. Environmental monitored as part time series done using satellite remote sensing. In addition anomalous rainfall surge, changes sea surface temperature chlorophyll concentration during after Ian favored conclusion, coupled environmental data sensing provides useful public health information constitute valuable tool proactively detect characterize pathogens, vibrios. These can aid development early warning systems yielding larger source for climate change. IMPORTANCE Evidence suggests warming temperatures spread potentially emergence disease globally. Following State sharp number deaths. Hence, monitoring vibrios, influencing their occurrence is critical health. Here, DNA used investigate genomic diversity , both potential coastal waters Additionally, microbial community profiled presence other microorganisms (bacteria, fungi, protists, viruses) present samples. Long-term showed optimal related pathogens. Collectively, results will be develop predictive risk models

The msbB gene, encoding a lipid A phosphatease, is crucial for lipopolysaccharide (LPS) synthesis in Gram-negative bacteria and plays critical role their virulence. This study investigated the of Vibrio parahaemolyticus, significant marine pathogen causing gastroenteritis humans infections aquatic animals. We constructed an deletion mutant (ΔmsbB) complementary strain (CΔmsbB) using homologous recombination. growth, outer membrane permeability, stress antibiotic sensitivity, biofilm formation, swarming motility, virulence wild-type (WT), ΔmsbB, CΔmsbB strains were assessed. Additionally, pathogenicity ΔmsbB was evaluated L. vannamei shrimp models. results showed that gene successfully deleted complemented, its did not impair bacterial growth. However, exhibited increased reduced resistance to stresses antibiotics, defective motility. In Tetrahymena co-culture, attenuated infected with strain, cumulative mortality rate 22%, significantly lower than 62% observed WT strain. Moreover, expression levels immune-related genes hepatopancreas group, indicating reduction infection capability pathogenicity. These findings indicate V. parahaemolyticus suggest potential target therapeutic interventions vaccine development against infections.

Vibrio parahaemolyticus is an aquatic animal pathogen. Recently, the detection rate of V. in freshwater products has exceeded that seafood products, and strains isolated from exhibit better growth conditions low-salinity environments. This study based on a food risk activity Changzhou, Jiangsu Province, China, investigating variation halophilism virulence two groups under different salt concentrations. Under 0%, 0.5%, 1% salt, showed faster than those seawater. In comparison, seawater group 2% 3% grew growing status foregoing low-salt concentration environment. The cytotoxicity produced by was approximately 1.4 times higher 0.5% compared to corresponding experimental group. increased nearly 20% groups. altered adapted research will be helpful establishing local global control strategy against diseases resulting parahaemolyticus.

Climate change is having increasingly profound effects on human health, notably those associated with the occurrence, distribution, and transmission of infectious diseases. The number disparate ecological parameters pathogens affected by climate are vast expansive. Disentangling complex relationship between these variables critical for development effective countermeasures against its effects. pathogen Vibrio vulnificus , a naturally occurring aquatic bacterium that causes fulminant septicemia, represents quintessential climate-sensitive organism. In this review, we use V . as model organism to elucidate intricate network interactions climatic factors pathogens, objective identifying common patterns which affecting their disease burden. Recent findings indicate in regions native or related climate-driven natural disasters chief contributors outbreaks. Concurrently, increasing environmental suitability areas non-endemic diseases, promoting surge populations dynamics, thus elevating risk new We highlight potential drivers aggravating threat under both scenarios propose measures mitigating impact. By defining mechanisms influences burden, aim shed light dynamics disease-causing agents, thereby laying groundwork early warning systems broadly applicable control measures.
