Pattern recognition in crustaceans

A recent detailed study using Aeromonas hydrophila mutants with defects on either different steps in the biosynthesis of LPS or defective with respect to other putative virulence factors flageUa, secretion systems, porins, siderophores, etc. has demonstrated the role of LPS in triggering melanisa-tion. In particular, the 0 34 antigen and the outer core of the LPS are crucial for both virulence and ability to induce melanisation in crayfish (Noonin et al., 2010). 

Lectins are proteins that non-covalently bind specific sugars without cata-lytically reacting with them. Lectin-binding to carbohydrates on cells, viral
