Preparation of Outer Membrane Vesicle from Escherichia coli
Bio-Protocol, 2013 Outer membrane vesicles (OMVs) are spherical bilayered phospholipids of 20-200 nm in size produced from all Gram-negative bacteria and Gram-positive bacteria investigated to date.

Outer membrane vesicle-mediated serum protection in Aggregatibacter actinomycetemcomitans
Journal of Oral Microbiology, 2020 Aggregatibacter actinomycetemcomitans belongs to the HACEK group of fastidious Gram-negative organisms, a recognized cause of infective endocarditis. A. actinomycetemcomitans is also implicated in periodontitis, with rapid progress in adolescents.

DNA Inversion Regulates Outer Membrane Vesicle Production in Bacteroides fragilis. [PDF]
PLoS ONE, 2016 Phase changes in Bacteroides fragilis, a member of the human colonic microbiota, mediate variations in a vast array of cell surface molecules, such as capsular polysaccharides and outer membrane proteins through DNA inversion.

A Bilayer-Couple Model of Bacterial Outer Membrane Vesicle Biogenesis
mBio, 2012 Gram-negative bacteria naturally produce outer membrane vesicles (OMVs) that arise through bulging and pinching off of the outer membrane. OMVs have several biological functions for bacteria, most notably as trafficking vehicles for toxins ...

Bacterial Outer Membrane Vesicles as Antibiotic Delivery Vehicles [PDF]
Frontiers in Immunology, 2021 Bacterial outer membrane vesicles (OMVs) are nanometer-scale, spherical vehicles released by Gram-negative bacteria into their surroundings throughout growth. These OMVs have been demonstrated to play key roles in pathogenesis by delivering certain biomolecules to host cells, including toxins and other virulence factors.

Polymorphic Regulation of Outer Membrane Lipid A Composition
mBio, 2016 The importance of the polymorphic-phase behavior of lipid A structural variations in determining their endotoxic activities has been recognized previously, but any potential role for lipid A polymorphism in controlling outer membrane structure and ...
