Secretory IgA N-glycans contribute to the protection against E. coli O55 infection of germ-free piglets [PDF]

Mucosal Immunology, 2021
Mucosal surfaces are colonized by highly diverse commensal microbiota. Coating with secretory IgA (SIgA) promotes the survival of commensal bacteria while it inhibits the invasion by pathogens. Bacterial coating could be mediated by antigen-specific SIgA recognition, polyreactivity, and/or by the SIgA-associated glycans.

Biochemical characterization of an α1,2-colitosyltransferase fromEscherichia coliO55:H7 [PDF]

Glycobiology, 2015
Colitose, also known as 3,6-dideoxy-L-galactose or 3-deoxy-L-fucose, is one of only five naturally occurring 3,6-dideoxyhexoses. Colitose was found in lipopolysaccharide of a number of infectious bacteria, including Escherichia coli O55 & O111 and Vibrio cholera O22 & O139. To date, no colitosyltransferase (ColT) has been characterized, probably due to
