近八年来,对腹泻的认识有了新的进展.了解得最全面的大概是霍乱弧菌的肠毒素引起的损害.近已证实,产生肠毒素的埃希氏大肠杆菌是世界性传播的病原.作者指出,埃希氏大肠杆菌引起腹泻必须具备两个因素:(1)细菌可于小肠繁殖(不是侵袭);(2)细菌能分泌一种或两种肠毒素(即一种不耐热的和霍乱弧菌密切相关的肠毒素和一种耐热的、非抗原性的、低分子量的肠毒素,它影响着液体向小肠内灌注).具有上述两种特性的引起腹泻的埃
In the recent eight years, new advances have been made in the understanding of diarrhea, and the most comprehensive understanding is about the damage caused by enterotoxin of V. cholerae. It has been confirmed that enterotoxigenic Escherichia coli is a worldwide transmission pathogen The authors point out that Escherichia coli must have two factors that cause diarrhea: (1) bacteria can multiply in the small intestine (not invasive); (2) bacteria can secrete one or two enterotoxins Of enterotoxins closely related to Vibrio cholerae and a thermotolerant, non-antigenic, low molecular weight enterotoxin that affects the infusion of liquid into the small intestine.)
