[Intestinal receptors for adhesive fimbriae of Escherichia coli in swine--a literature review].

This review describes the mechanism of intestinal colonization by enterotoxigenic and enterotoxaemic Escherichia (E.) coli in swine. Colonization depends on specific binding between adhesive fimbriae and receptors on the enterocytes. Special focus is given on the occurrence of specific intestinal receptors for the fimbrial antigens F4 (K88), F5 (K99), F6 (987P) and F41. The demonstration of these receptors allows the identification of susceptible and resistant pigs. Furthermore unclassified adhesive fimbriae of E. coli isolated from pigs with postweaning diarrhea and edema disease are described. Finally the present knowledge is discussed in context with protection of animals against infections.
