Polymicrobial infections threaten the health of humans and animals but remain understudied in natural systems. We recently described Pacific Oyster Mortality Syndrome (POMS), a polymicrobial disease affecting oyster production worldwide. In French Atlantic coast, involves coinfection with ostreid herpesvirus 1 (OsHV-1) virulent Vibrio . However, it is unknown whether consistent populations are associated POMS different regions, how contribute to POMS, they interact OsHV-1 during...
Environmental Vibrio strains represent a major threat in aquaculture, but the understanding of their virulence mechanisms heavily relies on transposition knowledge from human-pathogen vibrios. Here, genetic bases harveyi ORM4 towards European abalone Haliotis tuberculata were characterized. We demonstrated that luxO, encoding regulator quorum sensing system, is crucial for this strain, and its deletion leads to decrease swimming motility, biofilm formation, exopolysaccharide production....
The Vibrio genus includes bacteria widely distributed in aquatic habitats and the infections caused by these can affect a wide range of hosts. They are able to adhere numerous surfaces, which result biofilm formation that helps maintain them environment. involvement lifestyle virulence pathogens organisms remains be investigated. harveyi ORM4 is pathogen responsible for an outbreak European abalone Haliotis tuberculata populations. In present study, we used dynamic culture technique coupled...
Medulloblastoma (MB), the most common brain pediatric tumor, is a pathology composed of four molecular subgroups. Despite multimodal treatment, 30% patients eventually relapse, with fatal appearance metastases within 5 years. The major actors metastatic dissemination are lymphatic vessel growth factor, VEGFC, and its receptors/co-receptors. Here, we show that VEGFC inversely correlated to cell aggressiveness. Indeed, decreases MB proliferation migration, their ability form pseudo-vessel in...
Nitrogen (N2 ) fixation, or diazotrophy, supports a large part of primary production in oceans. Culture-independent approaches highlighted the presence abundance marine non-cyanobacterial diazotrophs (NCD), but their ecophysiology remains elusive, mostly because low number isolated NCD and lack available genetic tools for these isolates. Here, dual functional approach allowed unveiling affiliated to species Vibrio diazotrophicus. Physiological characterization first mutant obtained so far...

Abstract Polymicrobial diseases significantly impact the health of humans and animals but remain understudied in natural systems. We recently described Pacific Oyster Mortality Syndrome (POMS), a polymicrobial disease that impacts oyster production is prevalent worldwide. Analysis POMS-infected oysters on French North Atlantic coast revealed involves co-infection with endemic ostreid herpesvirus 1 (OsHV-1) virulent bacterial species such as Vibrio crassostreae . However, it unknown whether...
