产毒素型大肠杆菌(ETEC)是引起小儿急性腹泻及旅游者腹泻的主要原因。其致病机理主要为ETEC可以产生肠毒素即热敏肠毒素(LT)和热稳定肠毒素(ST),从而激活肠粘膜细胞上的鸟核苷酸环化酶,改变肠液和电介质的转运而引起分泌进。ST和LT基因探针虽已用于该菌的快速诊断,但在基层条件的限制,有时应急情况下,一时不能解决问题。95年
Toxin-producing Escherichia coli (ETEC) is the main cause of acute diarrhea in children and tourists diarrhea. Its pathogenesis is mainly that ETEC can produce enterotoxins, heat-sensitive enterotoxin (LT) and heat-stable enterotoxin (ST), thereby activating the nucleoside cyclase on intestinal mucosal cells and changing the transport of intestinal fluid and the dielectric Cause secretion into. Although ST and LT gene probes have been used for the rapid diagnosis of this bacterium, they may not be able to solve the problem sometimes due to the restriction of grass-roots conditions and sometimes the emergency. 95 years
