Bdellovibrio species are naturally predatory, small, motile, Deltaproteobacteria that invade the periplasm of other larger gram-negative bacteria, killing and digesting them.
This is because lectins are tied directly to inflammation and autoimmune reactions in your body. Lectins are a form of protein found in nearly all plants and animals. They bind to the sugar molecules called polysaccharides that cover the surface of most cells in your body.
Lectin intolerance means the inability to deactivate the toxic lectin (prevent its binding to your cells) in the confines of your own body, be it in the gut, artery, organ, gland or brain. The lectin then proceeds to invoke immune responses that damage the cell to which it attaches and possibly surrounding cells.
