Annelids are capable of defending themselves from pathogens and of recognizing degenerated self tissue. These reactions require specialized immune mechanisms that are effected by proteins and cellular reactions. Hemolytic proteins are the most striking humoral defense molecules in the earthwormEisenia fetida. Beside their hemolytic activity these proteins possess agglutinating, antibacterial, cytotoxic, and clotting properties. Hemolytic proteins both from coelomocytes (CL39,41) and coelomic

Glycosylation was found for H1.In silicoanalyses of the hemolysins revealed two hemolysin isoforms and consensus sites for N-glycosylation and peroxidases proximal heme-binding ligand.
