When the researchers tested this approach in the gut bacterium Ruminococcus
gnavus, they uncovered separate populations of the microbe associated with healthy people and patients with Crohn's disease.
The weak acid pH between 6.7-6.9 has been reported the optimal for activity of cellulolytic bacteria namely Ruminococcus
flavefaciens, Fibrobacter succinogenes.
Compared with the Essentiale group, Bacteroidetes (at the phylum and class levels), Bacteroidales (at the order level), Prevotellaceae (at the family level), and Prevotella (at the genus level) were increased, while Firmicutes, Spirochaete (at the phylum level), Actinobacteria, Spirochaetes (at the class level), Clostridiales, Lactobacillales (at the order level), Ruminococcaceae, Lachnospiraceae, Lactobacillales (at the family level), Lactobacillus, and Oscillospira, Treponema and Ruminococcus
(at the genus level) were decreased in the model group.
gnavus, and Fusobacterium were increased in patients with GAD compared with controls, while Faecalibacterium, Eubacterium rectale, Sutterella, Lachnospira, and Butyricicoccus were increased in healthy controls.
The animal-based diet increased the abundance of bile-tolerant microorganisms (Alistipes, Bilophila and Bacteroides) and decreased the levels of Firmicutes that metabolize dietary plant polysaccharides (Roseburia, Eubacterium rectale and Ruminococcus
The new study, published today in the Annals of Rheumatic Diseases online showed that 61 women diagnosed with SLE had roughly five times more gut bacteria known as Ruminococcus
gnavus, than 17 women of similar ages and racial backgrounds who did not have the disease and were healthy.
Individuals with dementia were also shown to have higher levels of the genus Ruminococcus
than those without dementia.
In particular, the relative abundance of ASVs of the genera Bacillus, Paenibacillus and Prevotella was higher in the gut of red deer in enclosures, and the relative abundance of ASVs of the genera Akkermansia, Bacteroides and Ruminococcus
were higher in the gut of free-ranging red deer.
This value can be considered as excellent for the development of ruminal bacteria, mainly cellulolytic bacteria (Fibrobacter succinogenes, Ruminococcus
albus and Ruminococcus
flavefaciens), which favor the digestion of fiber component of the diet (Van Soest, 1994).
In a study of 44 term infants with a family history of allergy, changes in the fecal microbiota, especially colonization with Ruminococcus
gnavus, preceded the onset of allergic symptoms (Gastroenterol.
