Clinical observations of possible neurotoxic activity in bushmaster (Lachesis muta muta) envenomations, coupled with the accepted ancestral relationship of Lachesis to other crotalids, suggested that Lachesis venom might contain a crotoxin-like molecule. Crude venom and gel-filtration fractions showed modest reactivity in enzyme-linked immunosorbent assays using rabbit polyclonal antibodies raised against the basic subunit of crotoxin, but no reaction was detected with a murine monoclonal antibody raised against the same antigen. Phospholipase assays, LD50 determinations and SDS-polyacrylamide gel electrophoresis indicated the presence of non-toxic phospholipases, but no crotoxin homologs. A higher mol.wt, toxic protein (60,000) with an LD50 of 0.07 micrograms/g in mice was isolated and purified, which induced gyroxin-like, rapid rolling motions in mice. Its amino terminal sequence shows considerable amino acid sequence identity with gyroxin from the venom of Crotalus durissus terrificus and other serine proteases.
