The afa-3 gene cluster determines the formation of an afimbrial adhesive sheath that is expressed by uropathogenic as well as diarrhoea-associated Escherichia coli strains. It contains six genes (afaA-afaF), among which the afaE3 gene is known to code for the structural AfaE-III adhesin (previously designated AFA-III), whereas no role has yet been identified for the afaD gene product. The afa-3 gene cluster is closely related to the daa operon that codes for an adhesin, the F1845 adhesin, which… CONTINUE READING
