In vitro scolicidal activity of synthesised silver nanoparticles from aqueous plant extract against Echinococcus granulosus.

At present, biosynthesis of AgNPs is a very effective method to produce less toxic nanoparticles. The vision of this research is to use three different plant extracts derived from leaves of Piper nigrum, Ziziphus Spina-Christi and Eucalyptus globulus for rapid biosynthesis of AgNPs. This is in addition to investigating the scolicidal activity against Echinococcus granulosus. The methods of UV-vis spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy-dispersive X-ray analysis (EDX) were employed to characterise the nanoparticles. UV spectra disclosed a maximum absorption at 437 nm for the biosynthesised AgNPs using EUCGLO extract. The XRD patterns revealed the (fcc) structure of the AgNPs with slightly shifted characteristic peaks at 2θ degree of 37.3˚ and 43.4˚, respectively. The scolicidal activity against E. granulosus revealed that the AgNPs, which were synthesised using Eucalyptus globulus, have powered scolicidal of 47.8 % after 45 min. which is comparable to the treatment by Albendazole.

Effectiveness of aqueous extracts of pumpkins seeds in the initial hydatid vitality isolated from outside of the body of sheep.

This study includes testing the effectiveness of seed pumpkin extract with intensive concentration (0.25, 0.50, 0.75, 1.00 g/ml) referring to time periods (1, 6, 12, 24) an hour depending on the initial primates vitality Echinococcus granulosus in the glass in order to reach an effective focus on killing the initial primates in a shortest possible period of time. The results of the current study show that a decrease in the vitality of initial primates when using the extracted aqueous of the pumpkin seeds up to 98.84% when focusing on 1.00 g/ml at time 24 hours when treated with extract aqueous of pumpkins seed.
