The clinical manifestations of and epidemiological data from 11 patients infected with Vibrio vulnificus admitted to Danish hospitals during the unusually warm summer of 1994 are reported. All patients contracted the disease after exposure to seawater; however, none had consumed seafood. Four patients developed bacteremia, one of whom subsequently died; nine patients, including the four with bacteremia, exhibited skin manifestations. Four patients contracted the disease while fishing; in at least one case the patient had handled eels. All Vibrio vulnificus strains were highly susceptible to 11 antimicrobial agents tested. Plasmid analysis revealed that 8 of 11 strains carried plasmids. Ribotyping using the enzyme HindIII on the 11 strains showed five different types, two of which comprised four strains each. The present study provides the first clinical and epidemiological data about a series of human Vibrio vulnificus infections from a temperate zone.

() is a Gram-negative, halophilic bacillus known for causing severe infections such as gastroenteritis, necrotizing fasciitis, and septic shock, with mortality rates exceeding 50% in high-risk individuals. Transmission occurs primarily through the consumption of contaminated seafood, exposure of open wounds to infected water, or, in rare cases, insect bites. The bacterium thrives in warm, brackish waters with high salinity levels, and its prevalence is rising due to the effects of climate change, including warming ocean temperatures and expanding coastal habitats.

Background: Environmental change in coastal areas can drive marine bacteria and resulting infections, such as those caused by , with both foodborne and nonfoodborne exposure routes and high mortality. Although ecological drivers of in the environment have been well-characterized, fewer models have been able to apply this to human infection risk due to limited surveillance.
Objectives: The Cholera and Other Illness Surveillance (COVIS) system database has reported infections in the United States since 1988, offering a unique opportunity to both explore the forecasting capabilities machine learning could provide and to characterize complex environmental drivers of infections.

Metagenomic sequencing is increasingly being employed to understand the assemblage and dynamics of the oyster microbiome. Specimen collection and processing steps can impact the resultant microbiome composition and introduce bias. To investigate this systematically, a total of 54 farmed oysters were collected from Chesapeake Bay between May and September 2019.

The global healthcare market increasingly demands affordable molecular diagnostics for field testing. To address this need, we introduce a lab-on-paper (LOP) platform that integrates isothermal amplification with a specially designed paper strip for molecular testing through an automated microfluidics process. The LOP system is engineered for rapid, cost-effective, and highly sensitive detection, using USB-powered thermal management and a wax valve mechanism.

With global temperatures on the rise and an expanding seafood trade, infections by Vibrio vulnificus, particularly in warm coastal areas like Hainan, China, are increasingly prevalent. These bacteria are notorious for causing grave infections with a high fatality rate. This study aims to dissect the clinical features, laboratory findings, treatment modalities, and patient outcomes associated with V vulnificus infections in Hainan Province.
