Protection Against Piglets Colibacillosis with Polyvalent Resident Factors of Enterotoxigenic Escherichia Coli

doi:10.3321/j.issn:1000-7091.2001.02.025

Abstract

Abstract: The resident factors K88,K99,987P and F41 had been combined with the specific receptors of the intestinal mucosa epithelial cells under the molecular immunoreaction,and the specific receptors had been blocked.The receptors blocked by resident factors couldn't attach the resident factors,and prevented the enterotoxigenic E.coli settling down the intestine.The results showed that the piglets infected protection rate was 100%,preventive protection rate was 100%.The experiments proved that the method was effective measures against piglets colibacillosis,and added new content to preventive model at present.

Key words: Piglets, Enterotoxigenic E.coli, Resident factors, Prevention
