Lactobacillus murinus: A key factor in suppression of enterogenous Candida albicans infections in Compound Agrimony enteritis capsules-treated mice. JOURNAL OF ETHNOPHARMACOLOGY 2023; 311:116361. [PMID: 36963475 DOI: 10.1016/j.jep.2023.116361] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/14/2023] [Revised: 03/04/2023] [Accepted: 03/04/2023] [Indexed: 06/18/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Compound Agrimony (FuFangXianHeCao, FFXHC) Enteritis Capsules is an ethnomedicine that is derived from Yi Nationality Herbal Medicine for enteritis treatment. We found that FFXHC reduced the mortality outcomes in enterogenic Candida albicans infected mice models and increased the abundance of Lactobacillus murinus in the intestines. Lactobacillus murinus exhibited comparable therapeutic effects to those of FFXHC in enterogenic Candida albicans infected mice. This study provides novel perspectives into the pharmacological mechanisms of FFXHC. AIM OF THE STUDY We investigated the mechanisms via which FFXHC inhibits C. albicans infections and its effects on L. murinus. MATERIALS AND METHODS Enterogenous C. albicans infection mice models were established and various parameters, including survival rate, weight change, number of colonies, treatment effects on intestinal mucosa, microecology, and immune cytokines evaluated. Susceptibility of C. albicans to L. murinus was evaluated in vitro. RESULTS Treatment with FFXHC reduced the number of colonies, improved the health status, enhanced the survival rates, increased the abundance of L. murinus, reduced damage to the intestinal mucosa, and elevated occludin as well as claudin-1 levels. Interestingly, TNF-α, IFN-γ, IL-10, IL-22, and IL-17A levels were increased while IL-1β levels were suppressed in the intestinal mucosa without any change in peripheral blood cytokine levels. Moreover, FFXHC promoted L. murinus proliferation. This study also confirmed the incubation-dependent anti-C. albicans effects exerted by the metabolic supernatants of L. murinus. CONCLUSIONS FFXHC effectively alleviated intestinal infections of C. albicans in mice and increased the abundance of L. murinus. Supplementation of L. murinus in food can achieve the effects that are comparable to those of FFXHC. Thus, L. murinus maybe essential in FFXHC-based treatment of intestinal C. albicans infections.

Abstract
Endometritis is persistent inflammation caused by bacteria, which can lead to infertility. Although traditional Chinese medicine (TCM) has been used to treat endometritis, the underlying mechanism is still unclear. Here, Baogong Decoction (BGD), a TCM compound, was used to treat mouse endometritis induced by Escherichia coli (E. coli), and then 16S rRNA sequencing and non-targeted metabolomics were used to investigate the change of uterine microbiota and metabolomes in serum and uterine after BGD treatment. Finally, the therapeutic effect of potential metabolites for treating mouse endometritis screened by combined omics analyses was verified using pathological model. The results showed that BGD treatment could effectively treat endometritis associated with the increasing relative abundance of Firmicutes, Bacteroides, Lactobacillus and Lactococcus, and the decreasing relative abundance of Cupriavidus and Proteobacteria. 133 and 130 metabolites were found to be potential biomarkers in serum and uterine tissue respectively. In serum and tissues, dehydroepiandrosterone (DHEA) and catechol were significantly increased in the BGD treatment versus the inflammation group. Results of combined omics analyses demonstrated that DHEA was positively correlated with changes in microbiota. Results of pathological model demonstrated that DHEA could cure endometritis effectively associated with the decreasing infiltration of inflammatory cells and expression of inflammatory factors in the uterus. In summary, our results demonstrated that BGD could cure endometritis in mice by modulating the structure of the uterine microbiota and its metabolites, in which DHEA may be one of the main components of the therapeutic effect of BGD.
