Cleavage of the N-linked oligosaccharide from the surfaces of Chlamydia species affects infectivity in the mouse model of lung infection

Infect Immun. 2006 May;74(5):3027-9. doi: 10.1128/IAI.74.5.3027-3029.2006.

Abstract

Previous studies determined that the Chlamydia glycan contains a high-mannose oligosaccharide, which is involved in attachment and infectivity of the organism, and that removal of the glycan decreases infectivity in vitro. The present study demonstrates that treatment of the organism with N-glycanase decreases or ablates infectivity in vivo.
