Objective: To determine the oral immunogenicity of B subunit of Escherichia coli Heat-labile enterotoxin expressed in transgenic potatoes.
目的探讨马铃薯表达的产肠毒素大肠杆菌热敏肠毒素B亚基口服免疫原性。
Besides, molecular structures, functions, mechanisms and gene detection of both heat-labile and heat-stable enterotoxins of etec in newborn piglets were discussed briefly too.
另外，从分子结构与功能、作用机理、基因检测三方面叙述了新生仔猪etec不耐热肠毒素和耐热肠毒素的研究进展。
The enterotoxins produced by Enterotoxigenic Escherichia coli (ETEC) are the main diarrhea-causing pathogen, and they were divided into two groups: heat-labile toxin(LT) and heat-stable toxin(ST).
肠毒素大肠杆菌（ETEC）是引起仔猪腹泻的主要致病菌，产生的肠毒素主要为热敏性肠毒素（LT）与耐热性肠毒素（ST）。
Special attention should be paid to the storage of heat labile or photosensitive products.
要特别注意热不稳定和光敏感的产品的储存。
