Efficacy of the Bunium persicum (Boiss) Essential Oil against Acute Toxoplasmosis in Mice Model

We evaluated the in vivo activity of Bunium persicum (Boiss) essential oil on infected mice with acute toxoplasmosis. To evaluate prophylactic effects, male NMRI mice received B. persicum essential oil at the concentrations of 0.05 and 0.1 mL/kg for 14 days. After 24 h mice were infected intraperitonealy with 1×104 tachyzoites of T. gondii, RH strain. In order to investigate therapeutic effects, mice were infected and then received B. persicum oil at the concentrations of 0.05 and 0.1 ml/kg two times a day for 5 days. The time/mean time of death in all infected mice and the number of tachyzoites from infected mice were recorded. The time/mean time of death of infected mice was 8 and 9 days after oral administration of B. persicum oil at the concentration of 0.05 and 0.1 mL/kg, respectively (P<0.05). In contrast, the time/mean time of death control group was 5 days. In addition, B. persicum significantly reduced the mean number of tachyzo­ites compared with control group. The time/mean time of death of infected mice was 6 and 7 days after oral administration of B. persicum essential oil at the concentra­tion of 0.05 and 0.1 mL/kg, respectively. In contrast, the time/mean time of death control group was 5 days. B. persicum especially at the concentration of 0.1 ml/kg significantly reduced the mean number of tachyzoites compared with con­trol group. The results showed the potential of B. persicum essential oil as a natu­ral source for the production of new prophylactic agent for use in toxoplasmosis.
