In vitro Scolicidal effects of Androctonus crassicauda (Olivier, 1807) venom against the protoscolices of Echinococcus granulosus

Hydatidosis is a zoonotic disease that commonly occurs in several places around the world, especially in the Middle East, due to infection by the larval stage of Echinococcus granulosus. This disease impacts an immense effect on the economic and public health of both humans and animals. Despite thei...

description Hydatidosis is a zoonotic disease that commonly occurs in several places around the world, especially in the Middle East, due to infection by the larval stage of Echinococcus granulosus. This disease impacts an immense effect on the economic and public health of both humans and animals. Despite their effectiveness, the unacceptable side effects and progressive resistance to scolicidal agents may limit their use. According to their biopharmaceutical activity and benefits, numerous studies have reported that scorpion venom and its derivatives represent important resources for therapeutic applications. Therefore, this study was designed to investigate the in vitro scolicidal consequences of the crude venom of Androctonus crassicauda on E. granulosus. For this purpose, protoscolices from infected organs of camel containing hydatid cysts were collected, separated, and washed. The scolicidal impacts of three different concentrations of the crude venom (20, 50, and 100 µg/mL) were tested at different times of exposure (30, 60, 120, and 240 min). Particularly, eosin exclusion test was used to examine the viability of the protoscolices. The study results showed that the crude venom at 100 μg/mL destroys all protoscolices after 240 min incubation. Also, the scolicidal activity of venom increased significantly according to the time of exposure. In conclusion, the crude venom of A. crassicauda demonstrated high scolicidal activity in vitro against protoscolices of hydatid cysts in low concentration and short exposure time. However, the efficacy of scorpion venom remains to be evaluated in vivo for the treatment of hydatidosis in both humans and domesticated animals.
