This study evaluated the effects of selenium yeast (SY) on rumen fermentation parameters, bacterial diversity, and expression pathways in goats. A total 18 Qianbei-pockmarked weather goats from Guizhou (body weight, 25.75 ± 1.75 kg; mean standard deviation) were assigned to three groups according a completely randomized design. Control group (CON, n = 6) kids fed basal diet, while treatment 1 (...

Background: The importance of microbiome in the progression and development colorectal cancer (CRC) has been discussed last decade. Like colon bacteria, other intestinal microorganisms, including archaea, could also be involved CRC progression, so it's important to work out archaeal (archaeome) composition among patients. Objectives: aim this study was determine archaeome healthy controls based...

Electromethanogenesis is a process of microbial electrosynthesis (MES) in which electroactive microorganisms reduce carbon dioxide (CO2) to produce methane (CH4), using cathode as an electron donor. The efficiency this reaction greatly determined by the establishment robust community on biocathodes, eventually affects global performance bioreactor. Moreover, development biofilm depends several ...

The digestion of plant biomass by symbiotic microbial communities in the gut of herbivore hosts also results in the production of methane, a greenhouse gas that is released into the environment where it contributes to climate change. As methane is exclusively produced by methanogenic archaea, various research groups have devoted their efforts to investigate the population structure of symbiotic...

BACKGROUND Studies of the bacterial communities of the gut microbiota have revealed a shift in the ratio of Firmicutes and Bacteroidetes in obese patients. Determining the variations of microbial communities in feces may be beneficial for the identification of specific profiles in patients with abnormal weights. The roles of the archaeon Methanobrevibacter smithii and Lactobacillus species have...

Vesicles comprised of the ether glycerolipids of the archaeon Methanobrevibacter smithii (archaeosomes) are potent adjuvants for evoking CD8(+) T cell responses. We therefore explored the ability of archaeosomes to overcome immunologic tolerance to self-antigens. Priming and boosting of mice with archaeosome-antigen evoked comparable CD8(+) T cell response and tumor protection to an alternate b...

Understanding of microbial communities inhabiting cattle vaginal tract may lead to a better comprehension of bovine physiology and reproductive health being of great economic interest. Up to date, studies involving cattle microbiota are focused on the gastrointestinal tract, and little is known about the vaginal microbiota. This study aimed to investigate the vaginal microbiome in Nellore cattl...

The human gut microbiome has profound influences on the host's health largely through its interference with various intestinal functions. As recent studies have suggested diversity in the human gut microbiome among human populations, it will be interesting to analyse how gut microbiome is correlated with geographical, cultural, and traditional differences. The Japanese people are known to have ...
