For example, … WebFeb 12, 2024 · As shown in many studies, Gram-negative (mostly motile) bacteria showed higher cell adhesion and growth rates in all stiffness than Gram-positive (non-motile) bacteria. However, some studies showed that bacterial adhesion to surface stiffness tends to be quantitatively similar regardless of bacterial motility. andree chedid rythmes WebBecause adhesion to epithelial cells is the most essential step of the infectious process for almost all bacterial pathogens, many efforts have been aimed at developing antiadhesin therapy. Sialyllactose (NeuAc[K2-3]Gal[L1-4]Glc), an inhibitor of the sialic acid-specific adhesin of H. pylori , was found to reduce the load of bacteria in monkeys.

WebNov 26, 2024 · These examples illustrate that the adhesion response upon surface contact can differ between bacterial species and even between single genetically identical cells.
