Bogan, B
Bogan, B. species (9, 11). Type 1 fimbriae carry adhesins that recognize terminal mannose residues in the Man1-3(Man1-6)Man conformation (10). This trisaccharide is exposed on many glycoproteins, and type 1 fimbriae mediate adherence to, e.g., human small and large intestinal (3) and urinary tract (30) epithelial cells. The adherence is abolished in the presence of PhiKan 083 mannose and hence is termed mannose sensitive (MS). The role of the MS adhesin in virulence has been debated, but it may play a role in urinary tract infection (7, 18, 28). Other adhesins, including those associated with P and S fimbriae, confer mannose-resistant (MR) adherence to uroepithelial and colonic epithelial cells (3, 30, 45). MR adhesins are well-known virulence factors in urinary tract infection, septicemia, and meningitis (23, 27, 37). Furthermore, P…
