PLA2G2A and diphtheria: For instance, myotoxicity in mice induced by Bothrops asper myotoxin II (a PLA2) was partially inhibited by antiserum raised against a peptide comprising residues 115–129 (coupled to a diphtheria toxoid) [67], while another study found prolongation of survival when mice immunized with three peptides from the C-terminus of ammodytoxin A (a PLA2) were challenged with Crotalus durissus terrificus and Vipera ammodytes snake venom [68].
