In autoaggregation (sometimes also called autoagglutination or flocculation), bacteria of the same type form multicellular clumps that eventually settle at the bottom of culture tubes. Autoaggregation is generally mediated by self-recognising surface structures, such as proteins and exopolysaccharides, which we term collectively as autoagglutinins.

Autoaggregation, adherence between identical bacterial cells, is important for colonization, kin and kind recognition, and survival of bacteria. It is directly mediated by specific interactions between proteins or organelles on the surfaces of interacting cells or indirectly by the presence of secreted macromolecules such as eDNA and ...

Formation of clumps, which are large, tightly-packed groups of cells held together by fibrin (ogen), has been demonstrated to be important for S. aureus virulence and immune evasion.

When cells or other particulates become clumped together by antibodies in a solution, this is termed agglutination. In immunology, the process is differentiated from precipitation by the relative size and solubility of the objects clumped together.

May 22, 2018 · Clumping factor A (ClfA), a cell-wall-anchored protein from Staphylococcus aureus, is a virulence factor in various infections and facilitates the colonization of protein-coated biomaterials. ClfA promotes bacterial adhesion to the blood plasma protein fibrinogen (Fg) via molecular forces that have not been studied so far.

Autoaggregation is generally mediated by self-recognising surface structures, such as proteins and exopolysaccharides, which we term collectively as autoagglutinins.

Oct 4, 2016 · Using confocal laser scanning microscopy and electron microscopy, we observed clumps of at least five rough-morphotype bacilli inside the phagocytic vesicles of macrophages at 3 h post-infection.

We are currently culturing several bacterial strains which grow as clumps in liquid medium (without agitation because they are micro-aerophillic) for CFU counting at a given OD (0.8 for...

Nov 27, 2022 · In conclusion, it is possible to explain a considerable amount of sIgA‐associated phenotypes in the gut through a simple but elegant mechanism: i.e. the most basic property of antibodies (target binding and clumping) enhancing the normal physiological processes of bacterial clearance under flow.

Jun 10, 2021 · Autoaggregation, adherence between identical bacterial cells, is important for colonization, kin and kind recognition, and survival of bacteria. It is directly mediated by specific interactions between proteins or organelles on the surfaces of interacting cells or indirectly by the presence of secreted macromolecules such as eDNA and ...
