Presence of cholinesterases in Echinococcus granulosus protoscolices

Abstract

Cholinesterases were detected in protoscolices of Echinococcus granulosus spectrophotometrically and electrophoretically. To characterize these activities as acetylcholinesterases or pseudocholinesterases, BW284C51 and the organophosphate anthelmintic Neguvón® were assayed as specific inhibitors of acetylcholinesterases, while Iso-OMPA was employed as specific inhibitor of pseudocholinesterases. We concluded that these Cholinesterase (ChE) activities would be considered as possible targets in chemotherapy.
