Abstract
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.
Highlights
Hydatidosis is one of the most important parasitic infections on public and veterinary health worldwide
CE is treated by a variety of ways, including chemical therapy, percutaneous aspiration injection and respiration (PAIR), surgical treatment, or the option of observation without surgical intervention [8,9]
Chemotherapy involves the use of albendazole, mebendazole or benzimidazole carbamates, chemotherapy is recommended as the only option in cases. where surgical treatment is not possible or when multiple cysts are available [9]
Summary
Hydatidosis is one of the most important parasitic infections on public and veterinary health worldwide. Cystic echinococcosis (hydatid cyst) (CE) was diagnosed by the basic methods of clinical examination, imaging and serological tests [5,6,7]. CE is treated by a variety of ways, including chemical therapy (drug therapy), percutaneous aspiration injection and respiration (PAIR), surgical treatment, or the option of observation without surgical intervention [8,9]. Where surgical treatment is not possible or when multiple cysts are available [9]. This option includes aspiration of the fluid, injection of lethal agents and re-suction. The noninvasive control option is carried out with the CE4-CE5 stages of cyst development according to the world health organization (WHO) classification to avoid the possibility that these cysts remain fertile.
