Berberine Alters Gut Microbial Function Through Modulation of Bile Acids Patricia G
Wolf et al. BMC Microbiology (2021) 21:24 https://doi.org/10.1186/s12866-020-02020-1 RESEARCH ARTICLE Open Access Berberine alters gut microbial function through modulation of bile acids Patricia G.

Ridlon3,4,5,15,16* Abstract Background: Berberine (BBR) is a plant-based nutraceutical that has been used for millennia to treat diarrheal infections and in contemporary medicine to improve patient lipid profiles. Reduction in lipids, particularly cholesterol, is achieved partly through up-regulation of bile acid synthesis and excretion into the gastrointestinal tract (GI). The efficacy of BBR is also thought to be dependent on structural and functional alterations of the gut microbiome. However, knowledge of the effects of BBR on gut microbiome communities is currently lacking. Distinguishing indirect effects of BBR on bacteria through altered bile acid profiles is particularly important in understanding how dietary nutraceuticals alter the microbiome. Results: Germfree mice were colonized with a defined minimal gut bacterial consortium capable of functional bile acid metabolism (Bacteroides vulgatus, Bacteroides uniformis, Parabacteroides distasonis, Bilophila wadsworthia, Clostridium hylemonae, Clostridium hiranonis, Blautia producta; B4PC2). Multi-omics (bile acid metabolomics, 16S rDNA sequencing, cecal metatranscriptomics) were performed in order to provide a simple in vivo model from which to identify network-based correlations between bile acids and bacterial transcripts in the presence and absence of dietary BBR. -

Exploring the Application of Ecological Theory to the Human Gut Microbiota Using Complex Defined Microbial Communities As Models
Exploring the application of ecological theory to the human gut microbiota using complex defined microbial communities as models by Kaitlyn Oliphant A Thesis presented to the The University of Guelph In partial fulfillment of requirements for the degree of Doctor of Philosophy in Molecular and Cellular Biology Guelph, Ontario, Canada © Kaitlyn Oliphant, December, 2018 ABSTRACT EXPLORING THE APPLICATION OF ECOLOGICAL THEORY TO THE HUMAN GUT MICROBIOTA USING COMPLEX DEFINED MICROBIAL COMMUNITIES AS MODELS Kaitlyn Oliphant Advisor: University of Guelph, 2018 Dr. Emma Allen-Vercoe The ecosystem of microorganisms that inhabit the human gastrointestinal tract, termed the gut microbiota, critically maintains host homeostasis. Alterations in species structure and metabolic behaviour of the gut microbiota are thus unsurprisingly exhibited in patients of gastrointestinal disorders when compared to the healthy population. Therefore, strategies that aim to remediate such gut microbiota through microbial supplementation have been attempted, with variable clinical success. Clearly, more knowledge of how to assemble a health promoting gut microbiota is required, which could be drawn upon from the framework of ecological theory. Current theories suggest that the forces driving microbial community assembly include historical contingency, dispersal limitation, stochasticity and environmental selection. Environmental selection additionally encompasses habitat filtering, i.e., host-microbe interactions, and species assortment, i.e., microbe-microbe interactions. I propose to explore the application of this theory to the human gut microbiota, and I hypothesize that microbial ecological theory can be replicated utilizing complex defined microbial communities. To address my hypothesis, I first built upon existing methods to assess microbial community composition and behaviour, then applied such tools to human fecal-derived defined microbial communities cultured in bioreactors, for example, by using marker gene sequencing and metabonomics. -

Gut microbiota are known to contribute to gastrointestinal (GI) diseases such as irritable bowel syndrome, inflammatory bowel disease, and colon cancer; however, the exact etiology remains elusive. Recently, sex and gender differences in GI diseases and their relation to gut microbiota has been suggested. Furthermore, the metabolism of estrogen and androgen was reported to be related to the gut microbiome. As gut microbiome is involved in the excretion and circulation process of sex hormones, the concept of “microgenderome” indicating the role of sex hormone on the gut microbiota has been suggested. However, further research is needed for this concept to be universally accepted. In this review, we summarize sex- and gender-differences in gut microbiota and the interplay of microbiota and GI diseases, focusing on sex hormones. We also describe the metabolic role of the microbiota in this regard. Finally, current subjects, such as medication including probiotics, are briefly discussed.

Sex Differences in Colonization of Gut Microbiota from a Man with Short
www.nature.com/scientificreports OPEN Sex differences in colonization of gut microbiota from a man with short-term vegetarian and inulin- Received: 28 June 2016 Accepted: 11 October 2016 supplemented diet in germ-free Published: 31 October 2016 mice Jing-jing Wang1, Jing Wang2, Xiao-yan Pang2, Li-ping Zhao2, Ling Tian1,* & Xing-peng Wang1,* Gnotobiotic mouse model is generally used to evaluate the efficacy of gut microbiota. Sex differences of gut microbiota are acknowledged, yet the effect of recipient’s gender on the bacterial colonization remains unclear. Here we inoculated male and female germ-free C57BL/6J mice with fecal bacteria from a man with short-term vegetarian and inulin-supplemented diet. We sequenced bacterial 16S rRNA genes V3-V4 region from donor’s feces and recipient’s colonic content. Shannon diversity index showed female recipients have higher bacteria diversity than males. Weighted UniFrac principal coordinates analysis revealed the overall structures of male recipient’s gut microbiota were significantly separated from those of females, and closer to the donor. Redundancy analysis identified 46 operational taxonomic units (OTUs) differed between the sexes. The relative abundance of 13 OTUs were higher in males, such as Parabacteroides distasonis and Blautia faecis, while 33 OTUs were overrepresented in females, including Clostridium groups and Escherichia fergusonii/Shigella sonnei. Moreover, the interactions of these differential OTUs were sexually distinct. These findings demonstrated that the intestine of male and female mice preferred to accommodate microbiota differently. Therefore, it is necessary to designate the gender of gnotobiotic mice for complete evaluation of modulatory effects of gut microbiota from human feces upon diseases. -

A quantitative molecular evaluation of fatty acids in human and animal platelets has already evidenced similarities between people suffering from depression and German Shepherds, suggesting that domestication has led dogs to be similar to humans. In order to verify whether humans and dogs suffering from similar pathologies also share similar microorganisms at the intestinal level, in this study the gut-microbiota composition of 12 German Shepherds was compared to that of 15 dogs belonging to mixed breeds which do not suffer from depression. Moreover, the relation between the microbiota of the German Shepherd’s group and that of patients with depression has been investigated. -

Bacterial Involvements in Ulcerative Colitis: Molecular and Microbiological Studies
BACTERIAL INVOLVEMENTS IN ULCERATIVE COLITIS: MOLECULAR AND MICROBIOLOGICAL STUDIES Samia Alkhalil A thesis submitted in partial fulfilment of the requirements for the award of the degree of Doctor of Philosophy of the University of Portsmouth Institute of Biomedical and biomolecular Sciences School of Pharmacy and Biomedical Sciences October 2017 AUTHORS’ DECLARATION I declare that whilst registered as a candidate for the degree of Doctor of Philosophy at University of Portsmouth, I have not been registered as a candidate for any other research award. The results and conclusions embodied in this thesis are the work of the named candidate and have not been submitted for any other academic award. Samia Alkhalil I ABSTRACT Inflammatory bowel disease (IBD) is a series of disorders characterised by chronic intestinal inflammation, with the principal examples being Crohn’s Disease (CD) and ulcerative colitis (UC). A paradigm of these disorders is that the composition of the colon microbiota changes, with increases in bacterial numbers and a reduction in diversity, particularly within the Firmicutes. Sulfate reducing bacteria (SRB) are believed to be involved in the etiology of these disorders, because they produce hydrogen sulfide which may be a causative agent of epithelial inflammation, although little supportive evidence exists for this possibility. The purpose of this study was (1) to detect and compare the relative levels of gut bacterial populations among patients suffering from ulcerative colitis and healthy individuals using PCR-DGGE, sequence analysis and biochip technology; (2) develop a rapid detection method for SRBs and (3) determine the susceptibility of Desulfovibrio indonesiensis in biofilms to Manuka honey with and without antibiotic treatment. -

Abstract: A mutualistic relationship between the composition, function and activity of the gut microbiota (GM) and the host exists, and the alteration of GM, sometimes referred as dysbiosis, is involved in various immune-mediated diseases, including inflammatory bowel disease (IBD). Accumulating evidence suggests that the GM is able to influence the efficacy of the pharmacological therapy of IBD and to predict whether individuals will respond to treatment. Additionally, the drugs used to treat IBD can modualate the microbial composition. The review aims to investigate the impact of the GM on the pharmacological therapy of IBD and vice versa. The GM resulted in an increase or decrease in therapeutic responses to treatment, but also to biotransform drugs to toxic metabolites. In particular, the baseline GM composition can help to predict if patients will respond to the IBD treatment with biologic drugs. On the other hand, drugs can affect the GM by incrementing or reducing its diversity and richness. Therefore, the relationship between the GM and drugs used in Citation: Franzin, M.; Stefanˇciˇc,K.; the treatment of IBD can be either beneficial or disadvantageous.
