This study was conducted to investigate the efficacy of a new formulation of MBZ oily suspension (MBZ-OS) in experimentally Echinococcus multilocularis-infected mice. MBZ-OS was prepared and administered to mice infected with E. multilocularis at 12.5 and 25 mg/kg for 14 consecutive days. Then, the cysts were collected, weighed and histologically examined. The results showed that the reduction rate of cyst weight induced by MBZ-OS at two doses was 95.23% and 92.67%, which was significantly higher than that of MBZ-1% tragacanth (positive control) at corresponding concentrations (87.41% and 69.47%), indicating that the treatment of alveolar echinococcosis at lower doses could be achieved by the use of MBZ-OS. This finding shows that MBZ-OS is also a promising formulation for alveolar echinococcosis as well as cystic echinococcosis and deserves to be investigated in clinical applications against echinococcosis.
