Functional Genomic Examinations Of Interactions Between Common Members Of The Human Gut Microbiota
… majority belonging to the Bacteroidetes and the Firmicutes. Differences in the balance between these phyla has been linked to obesity in mice and humans. However, little is known about their interactions in vivo. I have used comparative and functional genomics, proteomics and biochemical assays …

Baboon vaginal microbiota: an overlooked aspect of primate physiology
… human vaginal microbiota studies have shown that Firmicutes (mostly Lactobacillus spp.) predominate in the human vagina, with Actinobacteria (Gardnerella vaginalis) and Proteobacteria present in lower numbers. By contrast, Papio baboons harbored species not only of Firmicutes but also of …

Determining fecal bacterial profiles of a human-habituated wild chimpanzee population in Mahale Mountains National Park, Tanzania
… bacterial phyla: Actinobacteria, Bacteroidetes, Firmicutes, Mollicutes, and Proteobacteria, as well as uncultured and unidentified bacterial species. The remaining T-RFs corresponded solely to uncultured or unidentified bacteria. Firmicutes was the most common phylum, observed in 11 of the …

Understanding the development of gut microbiota and effect of Salmonella Typhimurium infection on gut microbiota in layers
… (week 40). The gut microbiota was dominated by Firmicutes at an early age which was replaced by phylum Bacteroidetes at the later stages. The gut microbiota richness reduced significantly at week 18, after shifting the flock from the rear to the production shed. Flock's production performance …

A seasonal comparison of the gut microbiome of the Southern Lesser Galago Galago moholi (A.Smith 1836)
… four major phyla present were Proteobacteria, Firmicutes, Bacteroidetes and Actinobacteria. The results showed only slight significances in variation in the taxonomic bacteria between seasons. However, the dominance of bacterial species from phylum Proteobacteria in summer and phylum Firmicutes …

METABOLICALLY HEALTHY AND UNHEALTHY OBESITY IN CHILDREN AND ADOLESCENTS: DIETARY IMPLICATIONS AND NEW OPPORTUNITIES FOR GUT MICROBIOTA MODULATION
… supplementation (500 mg/day) helped restore the Firmicutes/Bacteroidetes ratio, with sustained effects even after discontinuation. DHA supplementation drove a depletion in Ruminococcaceae and Dialisteraceae, and enrichment in Bacteroidaceae, Oscillospiraceae, and Akkermansiaceae. At genus level, …

The Utility of Culture Independent Methods to Evaluate the Fecal Microbiome in Overweight Horses Fed Orchard Grass Hay
… The abundance of bacteria belonging to the Firmicutes phylum increased (p = 0.02) in the feces of geldings fed 12% NSC hay (mean 8.06 range [8.03-8.11] log10 copies/g feces) compared to the feces of the same geldings when fed the 18% NSC hay (7.97 [7.97-7.98] log₁₀ copies/g feces). The …

Influence of vegetation on sediment bacterial community structure, microbial enzyme activities and phosphorus retention in constructed freshwater wetlands
… dominated by Acidobacteria, Proteobacteria and Firmicutes groups. Fewer sequences affiliated with the Firmicutes and Alphaproteobacteria were recovered from unvegetated sediments. Mesocosms were later dosed in August 2007 with 2.5mg/L of phosphorus to study the influence of vegetation on …

The Gut Microbiome: Is Fecal Matter Microbial Composition a Proxy for Intestinal Microbial Composition in Studies of the Microbiome
… shows significance between the two main phyla Firmicutes and Bacteroidetes, as well as main genera like <em>Odoribacter, Porphyromonas </em>and <em>Alistipes. </em>Relevant species <em>Desulfovibrio desulfuricans </em>and <em>Odoribacter splanchicus </em>were also found to be significantly …

A common and previously unknown ecological niche: the halorespiration of natural organochlorines in terrestrial soil and sediment
… halorespirers in other phyla such as the <italic>Firmicutes</italic>, have been relatively well characterized in contaminated systems and laboratory cultures, their distribution and role in uncontaminated terrestrial environments, where abundant natural organohalogens could function as potential …

Verteilung, Zusammensetzung und Aktivitäten mikrobieller Gemeinschaften in Wattsedimenten von der Oberfläche bis in mehrere Meter Tiefe
… Vertreter der Proteobacteria, in den tieferen Firmicutes. Zwei Stämme wurden als neue Arten, Roseobacter pelophilus sp. nov. und Roseovarius pelophilus sp. nov., vorgeschlagen. Die höchsten mikrobiellen Aktivitäten wurden nahe der Sedimentoberflächen gemessen. Exoenzymaktivitäten und …

Transcriptomic and metagenomic impacts of dietary energy of milk replacer in pre-weaned Holstein heifers
… E and R calves (P < 0.001). Bacteroidetes and Firmicutes represented the most abundant phyla for both E and R calves. Enhanced calves had 49.4% (5141 reads) Bacteriodetes and 36.4% (3789 reads) Firmicutes; whereas, R calves had 31.6% (2491 reads) Bacteriodetes and 41.1% (3236 reads) Firmicutes. …

Microbial phylogenetic diversity preserved in facies-specific modern, recent, Holocene and Pleistocene hot-spring travertine deposits of Yellowstone and Turkey
… in the Modern and Recent, to dominance by Firmicutes in the Holocene and Pleistocene. This is not unexpected, as endospores of Firmicutes are known to be resistant and also persist under harsh environmental conditions and therefore show higher relative abundance in ancient samples in …

Reconstitution and Mechanistic Studies on the Staphylococcal agr Quorum Sensing Circuit
… exist only in low-GC Gram-positive bacteria, or Firmicutes, whose cell membranes are predominantly highly anionic. AgrC also binds to ATP at an exceptionally weak affinity, likely due to its distinct adenine-binding pocket conserved only in a small subfamily of HK receptors existing also …
