Shared Reference Notes
- [1.1]
- The reduction of Bifidobacteria, the main producers of lactic acid capable of suppressing the growth of pathogenic bacteria, leads to an alteration of the immunitary system. - [1.2] [#High-fiber diet]
- Dietary fiber > competitive advantage to Bifidobacteria - [1.3]
- Loss of Bifidobacterium early in life has been associated with increased risk of developing autoimmunity, as seen in a birth cohort in Finland and atopic wheeze in another cohort in rural Ecuador. - [1.4] [#Premature infant]
- At the phylum level, #Firmicutes were the dominant phylum in 95% of all meconium samples (highest abundance observed in the VPT neonates as compared to PT and FT neonates); the second most dominant phylum was Bacteroidetes in 50% of all meconium samples. - [1.5] [#Antibiotic Therapy]
- Macrolide exposure was associated with reduced richness for twice as long as penicillin. - Antbiotic at childhud > reduced Bifidobacteria (5 studies) and #Lactobacillus (2 studies), and significant increases in #Proteobacteria such as E. coli (4 studies). - [1.6] [#Garlic]
- #Garlic fructan were found to selectively stimulate the growth of beneficial Bifidobacteria from human fecal microflora. - [1.7] [#Covid-19]
-anti-inflammatory bacteria, including Bifidobacteria species and #Eubacterium rectale, with lower severity, and pro-inflammatory bacteria such as #Prevotella copri with higher severity. - [1.8]
- #Anthocyanins promote an increase in beneficial bacteria, including #Lactobacilli and Bifidobacteria, while reducing pathogenic bacteria, including Staphylococcus aureus and Salmonella typhimurium. - [1.9] [#Inulin-Type Fructans]
- #Butyrate production may also be driven by bacteria unable to degrade inulin type fructans, but are capable of consuming #Acetate, producing #Butyrate, and utilising partially degraded carbohydrate from bifidobacteria. - [#Autism] - The depletion of #Bifidobacterium species has been reported widely in ASD. - Bifidobacteria are SCFA producers, and “psychobiotics” , and they modulate the gut–brain signals via γ-aminobutyric acid (GABA) and #Glutamate metabolism. - #Bifidobacterium have been reported to improve behavior and prevent #Depression-like behaviors in mice.
- [1.11] [#Bipolar disorder]
- Levels of #Faecalibacterium prausnitzii, #Bacteroides–#Prevotella group, #Atopobium Cluster, #Enterobacter spp. and #Clostridium cluster IV were higher in BD patients than healthy subjects along with a reduced Bifidobacteria to #Enterobacteriaceae ratio, having these changes a possible impact on brain function in these patients. - [1.12]
- on the 14th day of Wi-Fi irradiation, the biodiversity of the intestinal microflora decreased. - significant decrease in the number of Bifidobacteria from the first day of the experiment. - #Wi-Fi exposure caused the growth of bacteria of the genus #Helicobacter. - increase in the number of opportunistic pathogens of the #Flavobacteriia class. - [1.13]
- Bifidobacteria and #Lactobacillus spp. can produce micromolar concentrations of #GABA. - [1.14] [#Bifidobacterium adolescentis, #Bifidobacterium pseudocatenulatum] [#Fructooligosaccharides, #Human milk oligosaccharides, #Inulin]
- 2′FL/LNnT were bifidogenic for both age groups, 3′SL/6′SL and FOS/IN were exclusively bifidogenic for children and adults, respectively. - 3′SL/6′SL stimulated B. pseudocatenulatum (abundant in children), FOS/IN enhanced B. adolescentis (abundant in adults). - increased #Acetate, #Propionate and #Butyrate (only in adults) with product- and age-dependent differences. - [1.15]
- Hypolipidemic effects of Bifidobacteria have been demonstrated in animal models as well as in humans. - A plausible mechanism may be that microbiota activities promote bile acid biotransformation in vivo to regulate fat digestion and affect lipid metabolism, leading to a decrease in serum lipid levels
