Cystic echinococcosis (CE) is a cosmopolitan parasitic disease caused by infection with the larval stage of Echinococcus granulosus sensu lato. Thioredoxin peroxidase (TPx) may play an essential role in the antioxidant defence system of E. granulosus s.l. as neither catalase nor glutathione peroxidase activities have been detected in the parasite. However, it is not known whether TPx affects the survival and growth of E. granulosus s.l. during development. In this study, three fragments of siRNA specific for EgTPx (siRNA-1/2/3) were designed and transfected into protoscoleces of E. granulosus sensu stricto by electroporation. Quantitative real-time PCR and Western blotting analysis showed that siRNA-3 significantly reduced the expression of EgTPx. Coincidentally, knockdown of EgTPx expression in protoscoleces with siRNA-3 significantly reduced the viability of the parasite under oxidative stress induced by 0.6 mM H2O2. In vitro culture studies showed that protoscoleces treated with siRNA-3 reduced pre-microcyst formation. In vivo experiments showed that injecting mice intraperitoneally with protoscoleces treated with siRNA-3 resulted in a significant reduction in the number, size and weight of CE cysts compared with those of control animals. Silencing of EgTPx led to the impairment of growth of E. granulosus s.s. both in vitro and in vivo, indicating that EgTPx is an important factor for protoscoleces survival and plays an important role in the antioxidant defence against the host during development.
