Abstract: Piglet diarrhea is one of the most challenging problems what swine industry has faced at home and abroad,which causes a huge economic loss annually.Enterotoxigenic Escherichia coli (ETEC) is the main pathogenic bacteria of piglet diarrhea,whose pathogenicity depends on the co-effect of adhesion and enterotoxin.As the research methods innovate,the researchers at home and abroad have got important breakthroughs in the development of ETEC vaccines.This article introduced the pathogenic characters of ETEC,and summarized the progress on the development of all kinds of vaccines against ETEC.

Key words: enterotoxigenic Escherichia coli (ETEC); vaccine; piglet diarrhea; adhesion; enterotoxin
