Effect of cyclosporin A on the survival and ultrastructure of Echinococcus granulosus protoscoleces in vitro

Abstract

Surgical treatment of human hydatidsosis involves the use of various scolicidal agents to kill infective Echinococcus granulosus protoscoleces that may disseminate into the peritoneal cavity during surgery and potentially re-infect the patient. Currently, no scolicidal agent is completely effective in killing intracystic protoscoleces in humans. Cyclosporin A (CsA) has previously been found to be lethal for E. granulosus protoscoleces in vitro. In this study, we further assessed the effectiveness of CsA as a scolicidal agent by testing the toxic effect of CsA at higher doses over various time-periods. Experiments were performed on activated and unactivated protoscoleces cultured in nutrient ..
