Abstract Background Vibrio and Shewanella spp. (VS) are climate-sensitive bacteria found in marine environments, which sometimes cause severe human infections. VS infections have risen globally, particularly Northern Europe. In this study, we aimed to describe the epidemiology of Norway explore environmental factors climate conditions as predictors for public health responses. Methods We conducted a retrospective cross-sectional study reported from 2014 2018. Epidemiological data were collected through nationwide survey microbiology laboratories. Environmental data, including seawater temperature (SWT), salinity (SWS), atmospheric (AT), rainfall (RF), obtained Norwegian monitoring systems. Negative binomial regression adapted time-series was used estimate short-term effect on number cases. Results A total 303 with most cases (63%) occurring Southeast region Norway. SWT, SWS, AT showed significant correlations cases, gradual non-linear increase risk above 13°C [RR 1.60; CI(95%):1.02,2.8]. 1-month lag observed increased SWT predicting No association RF at national level, but regional differences observed. Conclusions influenced by conditions. Validation existing real-time models could enhance early responses inform preventive measures at-risk population

Abstract Background Zostera marina is an important ecosystem engineer influencing shallow water environments and possibly shaping the microbiota in surrounding sediments water. Z. typically found marine systems, but it can also proliferate under brackish conditions. Changes salinity generally have a strong impact on biota, especially at salty divide between 6 9. To better understand of interaction sediment microbiota, we investigated effects meadows across range 6–15 Baltic Sea during summer using 16S 18S rRNA gene amplicon sequencing. Results Salinity was most factor for structuring within both sediment. The presence affected composition bacterial eukaryotic community alpha diversity However, this effect confined to alpha-mesohaline conditions (salinity 9–15). below 9 insignificant. Conclusions Increasing associated with longer leaf length , causing increased canopy height, which affects through reduced velocity. Hence, propose that may be major predictor explaining ’s interactions 9–15. These findings emphasize importance physical meadow services implications management changing climate.

Organic molecules exuded into water column by marine organisms represent a significant portion of dissolved organic matter (DOM) that modulates biochemical interactions. Secreted allelochemicals have been suggested to be involved in regulation pathogen abundance seagrass meadows, however, exometabolome has remained unstudied. We aimed identify exometabolites, within and outside explore their potential involvement suppression under varying environmental conditions. collected seawater (SW) samples from eelgrass (Zostera marina)-vegetated (V) non-vegetated (NV) areas across 5 locations spanning 270 km coastline along the German Baltic Sea. Comparative LC-MS/MS-based untargeted computational metabolomics combined with statistical analyses machine learning tools were employed pinpoint (exo)metabolomic signatures leaves. Simultaneously, we measured abiotic parameters three common pathogenic taxa seawater, investigated spatiotemporal variations. Here show correlation biomass reduction effect increasing temperature, eutrophication anthropogenic influences. Exometabolomics studies revealed exudates contributed significantly overall DOM at molecular level, while SW overlying meadows contained many chemical features unique leaf metabolome. identified four flavone aglycones as key biomarkers distinguishing SW-V SW-NV samples. Their drastically increased concentrations correlated lowest biomass, suggesting role regulation. These analytical microbiological approaches indicate flavones are defensive released upon stress serve bioindicators eelgrass' sanitation effect.

Background The Vibrio genus comprises several bacterial species present in the Baltic Sea region (BSR), which are known to cause human infections. Aim To provide a comprehensive retrospective analysis of -induced infections BSR from 1994 2021, focusing on ‘big four’ – V. alginolyticus , cholerae non-O1/O139, parahaemolyticus and vulnificus eight European countries (Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Poland Sweden) bordering Sea. Methods Our includes data infections, distribution coastal waters environmental received national health agencies or extracted scientific literature online databases. A redundancy was performed determine potential impact independent variables, such as sea surface temperature, salinity, number designated beaches year, infection rate. Results For conducting surveillance, we observed an exponential increase total (n = 1,553) across over time. In Sweden numbers spp. caused by positively correlate with increasing temperature. Salinity emerged critical driver abundance. Furthermore, our proposed statistical model reveals 12 20 unreported cases Lithuania Poland, respectively, no surveillance. Conclusions There discrepancies surveillance monitoring among countries, emphasising need for programmes these pathogens protect health, particularly context climate change.

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.

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.
