ABSTRACT
AIMS:
To observe the therapeutic effects of vaginal infusion of probiotic Clostridium butyricum WZ001 on bacterial vaginosis (BV) in mice. METHODS ANDRESULTS:
Female ICR mice were used to establish the model of BV by infecting oestrogen-treated mice with Escherichia coli, and then treated with high- and low dose of C. butyricum. Clinical indexes of mice in the C. butyricum-treated groups were significantly improved and comparable to those in the antibiotic group. Pap staining showed that neutrophil count was significantly increased after modelling and largely decreased after C. butyricum treatment (P < 0·01). Dynamic observation of E. coli and Lactobacillus showed that the number of E. coli significantly decreased in the C. butyricum-treated groups or in the antibiotic group with prolonged treatment (P < 0·01). Besides, the number of E. coli in the low-dose C. butyricum group was higher than that in either its high-dose counterpart or the antibiotic group respectively (P < 0·01). The number of Lactobacillus decreased evidently in the antibiotic group (P < 0·01), while that in the C. butyricum groups remained consistent. Moreover, C. butyricum inhibited the proliferation of E. coli by the experiment in vitro. The phosphorylation of nuclear factor-kappa B (NF-κB) p65 in vaginal tissue and the serum levels of inflammatory cytokines, IL-1ß, TNF-α and IL-6, increased after modelling and significantly decreased after treated with C. butyricum (P < 0·01), with no difference found when compared with the antibiotic group.CONCLUSION:
Clostridium butyricum inhibits the growth of pathogenic bacteria as well as the inflammatory response induced by E. coli and promotes the growth of Lactobacillus to maintain the vaginal micro-ecological balance. SIGNIFICANCE AND IMPACT OF THE STUDY Our results suggest that probiobitc C. butyricum WZ001 has a great potential in the clinical treatment of BV.Palavras-chave
