Abstract
The effect of artesunate (ART) on the pathology and mortality rate of in Schistosoma mansoni infected mice was comparatively studied with the current drugs of choice for the treatment of schistosomiasis mansoni: praziquantel (PZQ) and oxamniquine (OX). S. mansoni experimentally infected mice were treated at 9 th week of infection with ART, PZQ or OX at an oral dosage of 300 mg kg -1, 600 mg kg -1 and 100 mg kg -1, respectively. Untreated, infected mice and non-infected mice were added as controls. Samples of mice were sacrificed and examined for the pathological findings at 1 week, 1 month, and 3 months after treatment. At 1 week after treatment, both gross and microscopic lesions were observed. No significant differences were noted among the infected groups. Differences were observed at 1 month after treatment. The lesions decreased more rapidly in groups treated with PZQ and OX. At 3 months after treatment, there were significant differences in the pathological findings among groups. In the groups treated with PZQ and OX, the lesions were markedly reduced and rarely found, but they were clearly observed in the group treated with ART and in the untreated, infected group. High mortality was also recorded in the group treated with ART and in the untreated, infected group. Therefore, the treatment of S. mansoni infected mice at 9 weeks of infection with ART did not reduce the pathological findings or the mortality rate compared to treatment with the current recommended schistosomicides, PZQ and OX.
