由多种病原体感染后引起的腹泻,均称为感染性腹泻。细菌性痢疾、阿米巴痢疾、霍乱、副霍乱及肠结核等均可出现感染性腹泻,对这些疾病人们一段均较熟习,诊断不困难。随着对腹泻原因的深入研究,对某些易被忽视的感染性腹泻积累了许多资料,现笔谈如下。罗永芳:大肠杆菌性腹泻。大肠杆菌性腹泻由致病性大肠杆菌引起,与人类腹泻有关的大肠杆菌有两大类:产肠毒素大肠杆菌及侵袭性大肠杆菌,前者侵犯小肠,引起小肠分泌亢进,产生水样腹泻,不引起肠道炎性侵润,而后者主要侵犯结肠,引起炎性反应,产生痢疾样腹泻。病人及带菌者是本病的传染源。通过被污染的水及食品传播,可致暴发。各年龄组均有 Diarrhea caused by a variety of pathogens infection, are known as infectious diarrhea. Bacterial dysentery, amoebic dysentery, cholera, parasitic cholera and intestinal tuberculosis can occur with infectious diarrhea, people are more familiar with these diseases, the diagnosis is not difficult. With the in-depth study on the causes of diarrhea, a lot of information has been accumulated on some easily overlooked infectious diarrhea. Luo Yongfang: Escherichia coli diarrhea. Escherichia coli diarrhea caused by pathogenic E. coli, and diarrhea associated with human Escherichia coli has two categories: enterotoxin-producing Escherichia coli and invasive Escherichia coli, the former violation of the small intestine, causing hypersecretion of the small intestine, resulting in watery diarrhea, not Causing intestinal inflammatory invasion, which mainly infringe the colon, causing inflammatory reactions, resulting in dysentery-like diarrhea. Patients and carriers are the source of infection of this disease. Outbreaks can be caused by the spread of contaminated water and food. There are all age groups
