The nature of bacterial capsules is to ___. A. cause widespread blood clotting; B. allow phagocytes to engulf these bacteria; C. affect the virulence of these bacteria; D. have no effect on the virulence of bacteria 相关知识点: 试题来源:...
Unlike slime EPS that are dissolved in solution, capsule EPS have a lower solubility and are located at cell surface as peripheral capsules (Beech and Cheung, 1995). In addition to their distinct physical states, it has been reported that these two types of EPS display some different chemical...
Bacterial extracellular polysaccharides (EPSs) play critical roles in virulence. Many bacteria assemble EPSs via a multi-protein “Wzx-Wzy” system, involving glycan polymerization at the outer face of the cytoplasmic/inner membrane. Gram-negative specie

Encapsulated bacterial cells generally have greater pathogenicity because capsules protect the bacteria against white blood cells called phagocytes. A capsular coating blocks the mechanisms that phagocytes use to attach to and engulf bacteria. 胶囊由许多致病性细菌形成。 因为胶囊保护细菌免受称吞噬细胞的白...

Capsules are antiphagocytic, and can reduce the total amount of complement that is deposited on the bacterial surface and the number of pneumococcal cells that are trapped in neutrophil extracellular traps. Most pneumococcal isolates that have been investigated display phase variation between two forms ...
