Genetic analysis of K88-mediated adhesion of enterotoxigenic Escherichia coli.
Four cistrons (adh) involved in the expression of the K88 adhesion system have been identified and mapped. Three of these (adh A, adh B and adh C) are located in a single operon (I) whereas the fourth (adh D) is expressed from a separate promoter (operon II). The polypeptides encoded by these cistrons have been identified and their role in the formation and regulation of K88 fimbriae (pili) is discussed.
