The present research explained the impact of ultrasound on the viability of Echinococcus granulosus protoscolices in vitro application of fixed frequency waves at 20000 pulse/sec and 1.8 w/cm2, with different exposing periods, thirty, twenty, fifteen, twelve, ten and five seconds respectively, subsequently prevention of mice against interjected with minor hydatid cysts, in comparison with the control animals infected with protoscolices without exposure to ultrasound waves, depending on many criteria including the numbers, weights and diameters of developed hydatid cysts. The results displayed an obvious impact of ultrasound waves on Echinococcus granulosus protoscolices viability number by increase of exposure period in vitro, in addition to a decrease of 100% of hydatid cysts numbers in the dealt ones with 17% fertility exposed for 20 seconds, the reduction rate was 99.23% in the group of fertility 35% which exposed for 15 seconds, after four and five months of infection.
