Effects of BPQ treatments on survival of N. caninum infected mice. On day 0, Balbc mice were infected by intraperitoneal injection of 2 × 106 freshly purified N. caninum Nc-Liv tachyzoites. After 48 h, mice received buparvaquone (BPQ; 100 mg/kg) as suspension in corn oil either by intraperitoneal injection of a volume of 100 µl (i.p.), or orally by application of 100 µl by gavage (or). The control groups obtained the corresponding amount of the solvent only. The treatments were performed 5 times on a daily basis.
