“…Due to their remarkable capability for decomposition of a range of nutrient resources, including chitin and alginate, Vibrio may exert large impacts on biogeochemical cycling in coastal habitats ( Kopprio et al, 2017 ; Zhang et al, 2018 ). Furthermore, the genus Vibrio encompasses many facultatively symbiotic and potential pathogenic strains, such as Vibrio cholerae , Vibrio parahaemolyticus , and Vibrio vulnificus , which are all capable of infecting humans through the consumption of contaminated seafood ( Guin et al, 2019 ; hun Yoon and Waters, 2019 ; King et al, 2019 ). Since they drive major biogeochemical cycles and support food webs globally, Vibrio communities are a vital component of the marine ecosystem.…”

Responses of Free-Living Vibrio Community to Seasonal Environmental Variation in a Subtropical Inland Bay

Vibrio are widely distributed in aquatic environments and strongly associated with eutrophic environments and human health through the consumption of contaminated seafood. However, the response of the Vibrio community to seasonal variation in eutrophic environments is poorly understood. In this study, we used a Vibrio-specific 16S rRNA sequencing approach to reveal the seasonal distribution pattern and diversity of the Vibrio community in the Maowei Sea, Beibu Gulf of China. The Shannon diversity of the Vibrio community was highest in the summer, while β-diversity analysis showed that Vibrio community structures were significantly different between seasons. Distance-based redundancy analysis (dbRDA) and Mantel test analysis suggested that total dissolved nitrogen (TDN), total dissolved phosphorus (TDP), dissolved inorganic nitrogen (DIN), salinity, and temperature were the key environmental factors shaping the Vibrio community structure, indicating a strong filtering effect of trophic condition on Vibrio communities. Furthermore, through random forest analysis, V. fluvialis, V. alginolyticus, V. proteolyticus, V. splendidus, and the other eight Vibrio species were more sensitive to eutrophic changes. This study revealed seasonal changes in Vibrio communities and the influence of environmental variation on Vibrio community composition, contributing to a better understanding of their potential ecological roles in a subtropical inland bay.

“…The causative agent of cholera, V. cholerae , has been studied widely and it is known that its survival in the intestine is largely dependent on its ability to adhere to and colonise the intestinal epithelial cell surfaces (Yoon & Waters, 2019). Vibrio cholerae secretes, via a type‐2 secretion system, a tetra modular protein called GlcNAc binding protein A (GbpA), composed of an N‐terminal AA10 domain, two domains involved in bacterial cell‐surface binding, thereby enabling microcolony formation, and a C‐terminal CBM5/12 domain capable of binding to crystalline chitin that permits the bacteria to attach to and colonise a wide range of crustaceans (Wong et al ., 2012; Yoon & Waters, 2019). In addition to this, GbpA was also found to oxidatively degrade various forms of chitin.…”

On the expansion of biological functions of lytic polysaccharide monooxygenases

et al. 2022

Lytic polysaccharide monooxygenases (LPMOs) constitute an enigmatic class of enzymes, the discovery of which has opened up a new arena of riveting research. LPMOs can oxidatively cleave the glycosidic bonds found in carbohydrate polymers enabling the depolymerisation of recalcitrant biomasses, such as cellulose or chitin. While most studies have so far mainly explored the role of LPMOs in a (plant) biomass conversion context, alternative roles and paradigms begin to emerge. In the present review, we propose a historical perspective of LPMO research providing a succinct overview of the major achievements of LPMO research over the past decade. This journey through LPMOs landscape leads us to dive into the emerging biological functions of LPMOs and LPMO-like proteins. We notably highlight roles in fungal and oomycete plant pathogenesis (e.g. potato late blight), but also in mutualistic/commensalism symbiosis (e.g. ectomycorrhizae). We further present the potential importance of LPMOs in other microbial pathogenesis including diseases caused by bacteria (e.g. pneumonia), fungi (e.g. human meningitis), oomycetes and viruses (e.g. entomopox), as well as in (micro)organism development (including several plant pests). Our assessment of the literature leads to the formulation of outstanding questions, promising for the coming years exciting research and discoveries on these moonlighting proteins.

“…To date, the devastating diarrheal disease cholera pandemics have been occurred seven times, and it is still endemics in the world, responsible for up to 3 million cases and 100,000 deaths annually (Theriot and Petri, 2020). Vibrio cholerae is the causal organism of the disease cholera, usually infects humans through ingestion of contaminated water and food, colonizes on the surface of small intestine villi with the aid of toxin coregulated pilus (TCP), and then secretes cholera toxin (CT), causing watery diarrhea and vomiting that lead to severe dehydration and even death (Yoon and Waters, 2019). V. cholerae is gram-negative, curved and facultative bacterium, with a long unipolar flagellum.…”

Vibrio cholerae, the causative agent of cholera, could proliferate in aquatic environment and infect humans through contaminated food and water. Enormous microorganisms residing in human gastrointestinal tract establish a special microecological system, which immediately responds to the invasion of V. cholerae, through "colonization resistance" mechanisms, such as antimicrobial peptide production, nutrients competition, and intestinal barrier maintenances. Meanwhile, V. cholerae could quickly sense those signals and modulate the expression of relevant genes to circumvent those stresses during infection, leading to successful colonization on the surface of small intestinal epithelial cells. In this review, we summarized the crosstalks profiles between gut microbiota and V. cholerae in the terms of Type VI Secretion System (T6SS), Quorum Sensing (QS), Reactive Oxygen Species (ROS)/pH stress, and Bioactive metabolites. These mechanisms can also be applied to molecular bacterial pathogenesis of other pathogens in host.
