霍乱与副霍乱大多数无腹痛,是与细菌及其毒素作用机制有关。霍乱或副霍乱弧菌入胃后很快被胃酸杀死。当胃酸缺乏或大量饮水胃酸被稀释时,细菌不被杀死而进入小肠。在小肠的硷性肠液内和肠粘膜表面上繁殖,不侵入上皮细胞和粘膜下层,不引起炎症。繁殖过程中产生外毒素(肠毒素),与肠牯膜细胞膜上的受体发生反应,激活细 Most of the cholera and parasites have no abdominal pain and are related to the mechanism of action of bacteria and their toxins. Cholera or Vibrio cholerae quickly kill stomach acid after entering the stomach. Bacteria are not killed and enter the small intestine when achlorhydria is depleted or a large amount of drinking water is diluted. In the small intestine alkaline intestinal fluid and intestinal mucosal proliferation, do not invade epithelial cells and submucosa, does not cause inflammation. Exotoxin (enterotoxin) is produced during reproduction and reacts with receptors on the cell membrane of the gut membrane to activate fine
