| description | Oxyuriasis, caused by the nematode Enterobius vermicularis, is one of the cosmopolitan intestinal infections of humans. Aspiculuris tetraptera commonly infects mice and it is morphologically similar to E. vermicularis. Parasitic resistance reduces the efficiency of synthetic drugs and poses economic impacts on the dairy sector, thus necessitating novel anthelmintic agents. Olea europaea L. (Olive) is a bioactive plant with potent pharmacological activities. However, its effects on oxyurids are poorly known, and no studies are currently exploring olives’ anthelmintic potential. In this study, we investigated the pharmacokinetic behaviors of O. europaea leaves extract (OLE) and its phenolic compound oleuropein in mice infected with A. tetraptera, in comparison with Albendazole (ABZ), a standard drug used to treat parasitic worms. Fecal flotation method was used to identify the infestation with A. tetraptera eggs by examining the stool samples from mice. Infected animals were divided into 7 groups. 250 mg/kg, 500 mg/kg, and 1000 mg/kg doses of OLE, 5 mg/kg and 20 mg/kg doses of oleuropein, 10 mg/kg of ABZ and tap water were orally administered by gavage for 7 days during treatments. Drug efficacies and statistical differences between the treatments and controls were evaluated. Our results revealed 92.43 % efficacy of ABZ, similar to 92.19 % efficacy of 1000 mg/kg of OLE. At the same time, 250 mg/kg and 500 mg/kg concentrations of OLE remained 70.03 % and 63.18 % effective in reducing worm counts. Efficacy percentages of 5 mg/kg and 20 mg/kg of oleuropein were 9.27 % and 70.56 %, respectively. Statistical analysis of ABZ was significant compared to 1000 mg/kg of OLE, which was almost equal but insignificant. In general, our results confirm the anthelmintic potential of OLE and oleuropein against mice pinworms and open the way for targeted extraction of bioactive compounds from plants to optimize its use in human and veterinary medicine. |
