Shared Reference Notes

  - Depletion of bacteria by antibiotics is required to achieve high levels of C. albicans intestinal colonization in laboratory mice
• [1.2] 
  - Some bacteria impair the expression of FIAF and AMPK, increasing #Cholesterol and fatty acids synthesis, lipogenesis, but inhibiting lipolysis.
• [1.3] 
  - 117 microbial species in the blood of healthy individuals, most of which are commensals associated with other body sites.
• [1.4] 
  - Extra-virgin #Olive oil ingestion in rodents also can promote the growth of certain types of beneficial bacteria including species of #Lactobacillus, #Bifidobacterium, #Bacteroides, and #Clostridium, and members of the Erysipelotrichaeae.
• [1.5] [#Crohn’s disease, #Inflamatory bowel disease] 
  - CD-HPA microbiota from colonized mice was characterized by a decrease in known beneficial bacteria such as #Akkermansia muciniphila, #Alistipes putredinis, and #Ruminococcus bromii, previously shown to be reduced in IBD patients.
• [1.6] 
  - The biofilm matrix and its associated structure can limit the diffusion and permeability of antimicrobial agents toward the core of biofilms, allowing the embedded bacteria to survive and develop certain resistance mechanisms against antibacterial agents
• [#Eucalyptus oil] - 1,8-#Cineole, the major component of EC, is the potent antimicrobial ingredient, as it has been found effective against many bacteria, #Fungi, and viruses. - the higher the 1,8-#Cineole concentration, the greater the antimicrobial action. - 1,8-#Cineole can induce oxidative stress, causing bacterial membrane damage and leakage of the intercellular components. - EO can allow better membrane permeability for the conjugated antimicrobial agents, which can facilitate targeting intracellular components of such microorganisms
• [1.7] [#Postmenopausal] 
  - Gut bacteria that possess β-glucuronidase and/or β-galactosidase activity can metabolize #Estrogen including #Bifidobacterium, #Faecalibacterium, #Lactobacillus, #Veillonella
• [1.8] [#Clostridium sporogenes] [#Tryptophan] 
  - Two gut bacteria C. sporogenes and #Ruminococcus gnavus can convert Trp into #Tryptamine which is able to inhibit #Glucose-induced #Hyperglycemia and enhance insulin release.
• [1.9] [#Clostridioides difficile] [#Berberine] 
  - BBR has direct inhibitory effects on bacteria such as #Clostridium difficile, #Actinobacillus, and #Bacillus subtilis
• - Some oral bacteria (e.g., #Porphyromonas gingivalis, #Prevotella intermedia, #Aggregatibacter actinomycetemcomitans, and #Fusobacterium nucleatum) produce volatile #Sulfur compounds (VSCs), such as #Hydrogen sulfide (H2S), methyl mercaptan (CH3SH), dimethyl #Sulfide ((CH3)2S), and dimethyl disulfide (CH3SSCH3).
• [1.11] [#Ulcerative Colitis] [#Short Chain Fatty Acid] 
  - UC > depletion of SCFA-producing bacteria such as #Prevotella, #Roseburia, #Lachnospiraceae, and #Ruminococcaceae.
• [1.12] [#Pancreatic Cancer] 
  - The microbial-related metabolite panel includes indoleacyrlic acid, an #Indole-derivative, and #TMAO. - #TMAO- and indoleacrylic-acid-producing bacteria include those in the phyla of #Bacillota, #Bacteroidota, #Actinomycetota, and Pseudomonadota. - #Bacillota species such as Cs and Er and Bacteriodota species including Bt and Pd have been shown to be increased in fecal samples of patients with PDAC compared with control subjects. - Relative abundances of fecal #Collinsella aeofaciens, a species of #Actinomycetota, is associated with poor prognosis in PDAC.
• [1.13] 
  - conjunctival swabs from Bacterial #Keratitis patients contained significantly less #Actinobacteria and #Corynebacteria (determinate beneficial symbiotic bacteria), but significantly more #Gammaproteobacteria, #Pseudomonas, #Bacteroides, and EscherichiaShigella (common ocular pathogenic bacteria).
• [1.14] [#Antimicrobial peptides] 
  - Numerous species of bacteria within the microbiota contain #Superoxide dismutase genes which alterations might influence the redox balance of the intestinal epithelium in AMP expression.
• [1.15] [#Cancer] [#Probiotic] 
  - similar L-#Lactate-producing #Lactic acid bacteria commensal to other body sites are also significantly associated with survival in colorectal, lung, head and neck, and skin cancers.
• [1.16] [#Colorectal cancer] 
  - #Methanethiol as a biomarker for non-invasive early #Cancer detection. - Commensal bacteria residing in the colonic lumen can convert dietary #Methionine to #Methanethiol through MGL-catalyzed α,γ-elimination and γ-replacement reactions. - #Fusobacterium nucleatum, #Citrobacter freundii, #Morganella morganii,and several #Proteus species have been reported to contribute to intestinal #Methanethiol production
• [1.17] [#Infants] 
  - due to the reduced #Oxygen concentration,Citation38 anaerobic bacteria, i.e., Lentilactobacillus and #Lactobacillus, emerge during the 8th to 12th month.
• [1.18] [#Covid-19] [#mRNA vaccine] 
  - #Agathobacter, #Lactobacillus, #Bacteroides, and #Lachnospira were positively correlated with both spike IgG levels and spike-specific CD4+ T-cell responses. These bacteria with known immunomodulatory properties could contribute to higher immune responses to vaccinations
• [1.19] 
  - the bacteria in mucosal biopsy samples (termed the mucosal-associated microbiome) can differ significantly from those in feces
• [#Diabetes Type 2] - IR and faecal monosaccharides were lower in individuals who harboured more #Bacteroidales-type bacteria in their gut, potentially highlighting the role of #Bacteroidales-type bacteria (#Bacteroides, #Alistipes) in mediating IS.
• [1.21] [#Bisphenol A] 
  - #Bacilli taxon is the most prevalent Gram-positive bacteria capable of degrading BPA
• [1.22] [#Lipopolysaccharide] 
  - LPS is a byproduct of Gram-negative gut bacteria and is a biomarker of intestinal barrier dysfunction.
• [1.23] [#Short Chain Fatty Acid] 
  - SCFA-producing bacteria such as #Akkermansia, #Butyrivibrio, #Holdemania, #Anaerostipes, and #Intestinimonas were identified in this study as part of the gut microbiota associated with #Hypothyroidism. - SCFAs play a crucial role in the regulation of sodium/#Iodine symporter (NIS) expression in thyroid cells.
• [1.24] [#Colorectal cancer] 
  - inflammation induced by gut bacteria impacts the metabolism of all-trans #Retinoic acid (AtRA), resulting in diminished levels of AtRA, this reduction in AtRA levels has been implicated in the advancement of #Ulcerative Colitis (UC) and its associated CRC
• [1.25] 
  - an inflammatory stage, mediated by gut bacteria, may contribute to ND risk very early in life.
