[#Hypercholesterolaemia] - #Lactobacillus and Bifidobacterium, which act as beneficial bacteria in the gut, contribute to the prevention of diseases such as hypercholesterolemia [1.91] [#Obesity] - weight loss is associated with reduced #Butyrate production by specific gut microbiota bacteria, such as the #Lactobacillus and Bifidobacterium genera belonging to the #Firmicutes phylum [1.92] - GM mainly controls #Estrogen levels through the secretion of an enzyme called β-glucuronidase, which is encoded by several GM genera, including #Bacteroides, Bifidobacterium, #Escherichia, and #Lactobacillus [#Estrogen] - higher levels of taxa that encode for β-glucuronidase, which are mainly Bifidobacterium and #Escherichia, in #Endometriosis women compared with control women. [1.93] [#Moyamoya disease] - the relative abundance of the 2 genera, #Lachnoclostridium and #Fusobacterium, increased in the MMD group, while the relative abundance of the 2 genera, Bifidobacterium and #Enterobacter decreased in the MMD group. [1.94] [#Propionic acid, #Valeric acid] - The lower abundance of Bifidobacterium is the key feature of the microbiota composition associated with severe #Autism. ASD patients presented significantly higher levels of propionic and valeric acids than General Population at 4–7 years, but these differences disappeared at 8–10 years. - Bifidobacterium being reduced in children with severe ASD. [1.95] - P-#Inulin administration altered the composition of the gut microbiota significantly, with an increase in abundance of Bifidobacterium and #Anaerostipes > significant enrichment in microbial metabolites derived from saccharolysis. [1.96] - Nine species in the genus Bifidobacterium were predicted to be #Bilirubin reducers. [1.97] [#Covid-19] [#mRNA vaccine] - Bifidobacterium and #Faecalibacterium showed significant association with high spike IgG titers, irrespective of other factors - Enrichment of Bifidobacterium was correlated with CD4+ T-cell responses and higher antibody titers to parenteral and oral vaccinations. [1.98] [#Autism] - lower faecal #Bifidobacteria abundance in #Children with ASD compared to neurotypical #Children. - Bifidobacterium was decreased in ASD cases compared to controls. - #Bifidobacteria changes correlated with differently abundant metabolites from derivatives of #Tryptophan metabolisms. - dietary interventions either with Bifidobacterium strains or other bacterial strains and/or compounds that increase #Bifidobacteria levels in the gut have shown to improve, not only intestinal outcomes, but also ASD severity [1.99] [#Chronic periodontitis] - the microbiomes of periodontitis patients contained a greater abundance of the genus #Acidaminococcus, #Clostridium, #Lactobacillus, Bifidobacterium, #Megasphaera, and Romboutsiac. [#Lactobacillus plantarum] [#Lead] - L. plantarum CCFM8661 alleviate Pb toxicity by changing microbiota and metabolites > increase of Bifidobacterium and decrease of #Bilophila > Increased metabolites include #Taurine and #Xanthine in colon, #Lauric acid in serum. [1.101] [#Radiofrequency field] - #Bacillus and Bifidobacterium were the first two bacteria that are notably correlated with most of the differential metabolites, indicating they contribute greatly to the disturbance of microbial metabolism during RF exposure. [1.102] - #Faecalibacterium and #Agathobacter > can produce #Butyrate by cross-feeding with Bifidobacterium [#Clostridium clusters XIVa] - Along with Bifidobacterium, #Cranberry juice stimulated the growth of #Prevotella, #Clostridium XIVa and #Eggerthella, while #Bacteroides was not affected by the #Cranberry juice intake. - arabinogalactan > lead to an increase in Bifidobacterium population and to the acidification of the medium due to the important concentrations of #Formate, #Acetate and #Lactate produced by this genus when fermenting #Cranberry xyloglucans. - #Formate, #Acetate and #Lactate exert antibacterial effects and pH reduction to which #Bacteroides is sensitive [#Phenol] - #Cranberry (poly)phenols have an antimicrobial effect on #Bacteroides, allowing Bifidobacterium to consume #Cranberry oligosaccharides and occupy its microbial niche - fecal and plasmatic ratio of #Butyrate tended to increase in response to the #Cranberry extract, - the increase in the #Butyrate ratio was concomitant to a decrease of the #Acetate ratio, despite the bloom of several #Acetate-producing bacteria such as #Terrisporobacter (former #Clostridium), #Intestinibacter (former #Clostridium), #Dorea (former #Eubacterium) and Bifidobacterium - Species from Bifidobacterium can consume oligosaccharides to release #Acetate and #Lactate, and these intermediate metabolites can be converted into #Butyrate by specific bacteria, such as #Clostridium, by a butyryl-CoA:#Acetate CoA transferase - Bifidobacterium promotes the growth and activity of #Butyrate-producing bacteria, leading to an increase production of #Butyrate in the gut. [1.103] [#Bifidobacterium adolescentis, #Bifidobacterium catenulatum, #Bifidobacterium longum] [#Adult, #Aging] - The most abundant bifidobacterial species found in adults are B. adolescentis, B. catenulatum, and B. longum. - It has been observed that in later stages of life, with an increase in age, levels of Bifidobacterium further decrease. [#Cancer] - a lower abundance of gut resident Bifidobacterium is linked with more aggressive tumors. - Decreased levels of Bifidobacterium will not be able to synthesize enough ##Folate, it will elevate the risk of aneuploidies related to rectal #Cancer, leading to severity in rectal #Cancer cases. [#Gastric carcinoma, #Peptic ulcer] [#Bifidobacterium adolescentis, #Bifidobacterium bifidum, #Bifidobacterium breve, #Bifidobacterium longum, #Bifidobacterium pseudocatenulatum, #Chloracidobacterium thermophilum B, #Helicobacter pylori, #Limosilactobacillus (Lactobacillus) reuteri] - H. pylori infection alone is not sufficient to develop severe gastric abnormalities such as gastric cancer and gastric ulcers. - A lower abundance of gut resident Bifidobacterium genus with specific strains ( B. adolescentis, B. bifidum, B. breve, B. longum, B. moukalabense, B. pseudocatenulatum, and B. reuteri.) plays a significant role in developing severe gastric malignancy. [#Metabolic syndrome] - #Bifidobacteria play a major role in carbohydrate metabolism. #Bifidobacteria have a technique known as the “bifidshunt”, which specifically targets the enzyme #Fructose-6-phosphoketolase. Reduction in Bifidobacterium linked to metabolic dysfunction. - Lower levels of Bifidobacterium will not be sufficient to inhibit tumor growth via the TNF-α-mediated pathway, and therefore, they can participate in #Pancreatic Cancer progression. [1.104] - dysbiosis of the gut microbiota, characterized by a reduction in Bifidobacterium, is associated with increased disease activity in patients with #Autoimmune hepatitis [1.105] [#Autism] [#Triglyceride] - cord serum TG depletion in #Infants with future ASD, and these levels were found to be correlated with Bifidobacterium abundance at 1 year. [#Cognitive impairment] - In stool, Bifidobacterium abundance correlated with #4-hydroxyphenyllactate, which is a metabolite of #Tyrosine—a catecholamine precursor associated with cognitive function. [1.106] [#Diabetes Type 2] - #Blautia, #Faecalibacterium, Bifidobacterium, #Clostridium, #Anaerostipes, #Mediterraneibacter, and #Butyricicoccus abundances were relatively higher in healthy fecal samples than in prediabetic fecal samples. [1.107] [#Human milk oligosaccharides] [#Infants] - Intake of infant formula containing synthetic hMOS has been shown to increase Bifidobacterium abundance and that of its metabolites, especially #Acetate, in infant feces, and to reduce lower respiratory tract infections during the first year of life. [1.108] [#β-hydroxybutyrate] [#Keto diet] - β-hydroxybutyrate synthesized during KD is linked to reduced Bifidobacterium abundance. [#Metabolic Dysfunction-associated Steatohepatitis] - patients with #Obesity and NASH demonstrated an abundance of #Lactobacilli, while patients with NASH who were overweight displayed a diminished abundance of Bifidobacterium. - patients with lean NASH displayed a deficiency in Lactobacillus in comparison to their overweight and obese NASH counterparts. [1.109] - #Guar gum primarily enriches Actinobacteriota, specifically Bifidobacterium. [#Cognitive impairment] - In #Depression > Poor current cognitive function associated with lower relative abundance of Bifidobacterium [#Cognitive impairment] - higher abundance of #Bacteroidota and lower abundance of Bifidobacterium predict lower cognitive functioning. - Supplementing Bifidobacterium improves cognitive function in animal models and people with varying levels of #Cognitive impairment [1.111] - In aged mice, #Inulin restored potentially beneficial taxa including Bifidobacterium and key #Butyrate producing genera (e.g. #Faecalibaculum).References Notes[ ]
