Symbiotic, commensal, and pathogenic microorganisms employ cell-surface glycans as targets for interaction with the host. Surface proteins (adhesins or agglutinins) mediate binding to such glycan “receptors,” and many microbes depend on these interactions for success in the host. In addition, antagonistic interactions are mediated by secreted toxins that use surface glycan targets for internalization by various mechanisms. This chapter highlights examples of microbial lectins and their roles in pathogenicity. In addition, the modes of action of glycan-dependent toxins is discussed.
