What is the taxonomy of Methanobrevibacter?

Methanobrevibacter ruminantium (strain ATCC 35063 / DSM 1093 / JCM 13430 / M1) is a dominant ruminant, acetate-utilizer, methanogenic archaeon isolated from a bovine rumen. It can grow with H2 plus CO2 and formate.

What is the genus of Methanobrevibacter?

Balch and Wolfe 1981. Species. In taxonomy, Methanobrevibacter is a genus of the Methanobacteriaceae. The species within Methanobrevibacter are strictly anaerobic archaea that produce methane, for the most part through the reduction of carbon dioxide via hydrogen.

Where do termites live?

Most species live in the intestines of larger organisms, such as termites and are responsible for the large quantities of greenhouse gases that they produce. Mbr. smithii, found in the human intestine, may play a role in obesity.

What are the phyla of the gut microbiota?

The bacterial phyla representative of the human gut microbiota are Bacteroidetes, Firmicutes, Actinobacteria, Proteobacteria, and Verrucomicrobia. Archaeal representatives consist largely of the methanogens Methanobrevibacter and Methanosphaera. The complexity increases toward the lower taxonomic ranks, from phylum to species level, but analyses of cumulative abundance in metagenomic studies indicated that bacteria related to Faecalibacterium, Bifidobacterium, Roseburia, Ruminococcus, Subdoligranulum, Prevotella, Ruminococcus, Akkermansia, and Oscillospira represent common core bacteria in the Western adult population [6].

What is the intestinal microbiota?

Intestinal microbiota also produces some biogenic compounds such as free vitamins, bioactive peptides, and neurotransmitters like γ-amino butyric acid (GABA). The intestinal microbiota participates in the detoxification of xenobiotics and contaminants and the biotransformation of drugs or their metabolites [10].

How does gut microbiota affect MS?

Because MS is an inflammatory disease and the majority of MS drugs work by blocking proinflammatory pathways, it is reasonable to believe that the gut microbiota could influence the disease, by modulating the host immune response. The importance of gut bacteria in maintaining immune homeostasis, in part by keeping a balance between antiinflammatory ...

Is MS a pathogenic disease?

MS is an inflammatory disease in which both Th1 and Th17 cells are pathogenic; thus gut bacteria that are more abundant in MS patients can be considered proinflammatory/pathobionts, whereas less abundant gut bacteria can be considered antiinflammatory/symbionts.

What is short chain fatty acid?

Short-Chain Fatty Acids. This could be due to the ability of Clostridium strains to metabolize fiber and complex plant carbohydrates into short-chain fatty acids (SCFAs) that might play a crucial role in promoting the generation of the Treg population.

Is Prevotella a microbe?

Prevotella has emerged as a common gut microbe, with lower abundance in MS patients across geographical regions (USA, Europe, and Asia) [1,4]. Conversely Akkermansia and Acinetobacter calcoaceticus are linked with induction of a proinflammatory response.

Is IBD a continuous disease?

IBD is a continuous, relapsing, long-lasting and immunological disease that mostly occurs in young individuals ( Zhong et al., 2018 ). It is a broad term used for Crohn's disease (CD) as well as Ulcerative colitis (UC). Elucidating the role of epigenetic processes linked with microbial metabolites in IBD is important because it may contribute to the identification of new strategies for the prevention and treatment of IBD. Numerous studies that have investigated the interplay between gut dysbiosis and IBD are provided in Table 2. Pascal et al. revealed about six bacterial profiles including Faecalibacterium, Peptostreptococcaceae, Anaerostipes, Christensenellaceae, Collinsella and Methanobrevibacter that were significantly lowered in CD patients as compared to healthy individuals ( Pascal et al., 2017 ). A study on pediatric patients of CD has shown a decrease in the abundance of specific microbial species including Lactobacillus, Bifidobacteria, Eubacterium rectale, and Faecalibacterium prausnitzii ( Devaux and Raoult, 2018 ). It has been evident that two distinct patterns of meta-communities resides in patients suffering from CD including increase in the levels of pro-inflammatory hexa-acylated lipopolysaccharides producing microbial communities and decrease in SCFA-producing gut communities ( He et al., 2017 ). In Firmicutes and Bacteroidetes phyla, the levels of two butyrate producers, F. prausnitzii and B. fragilis, were found to be decreased in CD patients ( Sokol et al., 2008 ). Butyrate enhances the development of gastrointestinal barrier by regulating the expression of tight junctions proteins present between the epithelial cells ( Peng et al., 2009 ). Moreover, butyrate regulates differentiation of T-regulatory cells, and thereby participates in anti-inflammatory mechanisms ( Cleophas et al., 2019 ). Another microbiota study by Zhou and Zhi et al. showed that patients with active CD had lower levels of Bacteroides in comparison with healthy individuals. Hence, it has been suggested that decline in Bacteroides may be associated with CD ( Zhou and Zhi, 2016 ).
