H. Schroten et al., FAB-INDEPENDENT ANTIADHESION EFFECTS OF SECRETORY IMMUNOGLOBULIN-A ONS-FIMBRIATED ESCHERICHIA-COLI ARE MEDIATED BY SIALYLOLIGOSACCHARIDES, Infection and immunity, 66(8), 1998, pp. 3971-3973
S-fimbriated Escherichia coli strains cause sepsis and meningitis in n
ewborns and are known to recognize the carbohydrate sequence sialyl-(a
lpha 2-3)-galactoside. We show that adhesion of cloned S-fimbriated E.
coli to human epithelial cells is inhibited Fab independently by sial
yloligosaccharides on secretory immunoglobulin A (s-IgA), This indicat
es an anti-infective function of s-IgA (Fc), particularly in early hum
an milk.
