Abstract
There is strong correlation between changes in abundance of specific bacterial species and several diseases including schistosomiasis. Several studies have described therapeutic effects of curcumin (CUR) which may arise from its regulative effects on intestinal microbiota. Thus, we examined the impact of CUR on the diversity of intestinal microbiota with/without infection by Schistosoma mansoni cercariae for 56 days. Enterobacteriaceae was dominating in naive and S.mansoni infected mice group without CUR treatment, the most predominant species was Escherichia coli with R.D% = 80.66% and the least one was Pseudomonas sp. (0.52%). The influence of CUR on murine microbiota composition was examined one week after oral administration of high (40) and low (20 mg/kg b.w.) CUR doses 3 times, with 2 days interval. CUR induced high variation in Enterobacteriaceae family, characterized by significant (P< 0.001) reduction in E. coli and significant (P< 0.001) increase in Pseudomonas sp. in both naïve and S. mansoni-infected mice compared to untreated mice, in a dose-dependent manner. Additionally, our study showed the remarkable effects of high CUR doses on S. mansoni infection immunological and parasitological parameters. These data support CUR ability to promote Pseudomonas sp., known to produce schistosomicidal toxins, and offset the sequelae of murine schistosomiasis
