Abstract
We herein describe the establishment of single hepatic lesions of Echinococcus multilocularis in rats. A 3 mm incision was made on the liver with a surgical knife, and one small round vesicle of E. multilocularis (between 1 Ã 1 mm and <2 Ã 2 mm in diameter) was transplanted into the incision and covered with absorbable hemostat gauze. The presence and growth of the transplanted vesicle was monitored for 12 weeks using magnetic resonance imaging (MRI). Hepatic lesions, the metacestode of this parasite were confirmed in 12 of 17 infected rats (70.6%) by MRI and macroscopic examinations. The average size of the metacestodes with brood capsules at 12 weeks after the experimental transplantation of a single vesicle was 6.1 ± 2.5 mm Ã 4.4 ± 1.5 mm. The smallest size of the metacestodes detected by MRI was approximately 3 Ã 3 mm. This new approach of establishing single hepatic metacestodes of E. multilocularis in experimental animals is expected to be useful for analyzing the immune-pathological mechanisms of hepatic AE.
