The S-oxidizing symbiont of the bivalve Codakia orbicularis encodes all proteins required for biological nitrogen fixation. The symbiont's NifH is phylogenetically close to free-living N-fixing Proteobacteria associated with seagrass sediment.
The chemosynthetic symbionts of the bivalve Loripes lucinalis and nematode Laxus oneistus are found to encode nitrogen fixation genes, with evidence for active nitrogen fixation.
During bacterial infection, tryptophanyl-tRNA synthetase is secreted by monocytes and binds to macrophages via a TLR4–MD2 complex to induce phagocytosis and chemokine production, thereby serving as a primary defence system against infection.
Metagenomic, metatranscriptomic and metaproteomic approaches are used to resolve the taxonomic and functional characteristics of gastrointestinal microbiota from four families with multiple cases of type 1 diabetes mellitus.
Phylogenetic analysis defines the population and transmission structure of Listeria monocytogenes isolates and creates a global framework for epidemiological surveillance.Phylogenetic analysis defines the population and transmission structure of Listeria monocytogenes isolates and creates a global framework for epidemiological surveillance.
Inflammatory bowel disease dysbiosis networks were different between humans and dogs, with some species switching from positive to negative between groups. Stool samples were sufficient for dog-classification, whereas mucosal samples are required in humans.
The Verstraetearchaeota encode divergent methyl-coenzyme M reductase genes, which are required for methylotrophic methanogenesis, increasing methanogen diversity and the complexity of the global methane cycle.
The Pseudomonas aeruginosa quorum-sensing molecule 2-aminoacetophenone (2-AA) upregulates HDAC1 to reduce acetylation at cytokine promoters and promote host tolerance during infection.
Hydraulic conditions result in selective taxonomic pressures that determine the formation of biofilm or aggregate communities in experimental fluvial systems.
The UN Sustainable Development Goals aim to solve the most serious global economic, societal and environmental issues. The microbiology community is in a unique position to help tackle this ambitious agenda for sustainable development.
The spirochaete flagella, unlike those of other bacteria, are located entirely within the periplasm of the bacteria. New work highlights another unique spirochaete characteristic — an unusual covalent linkage that mediates flagellar hook self-polymerization and is required for motility.
