Total synthesis of a structurally complex zwitterionic hexasaccharide repeating unit of polysaccharide B from Bacteroides fragilis via one-pot glycosylation Article Open access 12 September 2024 Introduction In Gram-positive bacteria, a cell wall outside the plasma membrane determines shape, ensures integri...
For example; Bacteroides fragilis, B. ovatus, and B. thetaiotaomicron have A1γ-type peptidoglycan with 56–66% MurNAc O-acetylation, whilst the A1γ-type peptidoglycan of Akkermansia muciniphila displays both GlcNAc de-N-acetylation and MurNAc O-acetylation, the former representing approximately 87...
An increase of gut IL10-producing T Reg cells has been reported to be stimulated by colonization of germ-free mice with one of the following bacterial members: the human commensal bacterium Bacteroides fragilis, 46 Clostridium spp. mixtures, cluster IV and XIVa strains, or altered Schaedler ...
In eukaryotes, the MACPF fold also present in bacteria (e.g., Photorhabdus luminescens derived Plu-MACPF, BSAP-1 from Bacteroides fragilis and BT3439 from Bacteroides thetaiotaomicron) (Xu et al., 2010). The exact role of these bacterial MACPF proteins in infection is to be completely ...
Phage susceptibility, as determined by infection assays, demonstrates significant variations among strains of the same Bacteroides or Parabacteroides species, while these phages themselves are specific to their bacterial host species. Eight phages targeting a broad range of Bacteroides fragilis strains ...
consisted of mock bacterial community DNA at a concentration of 20 pg/µl: (i) a commercial mock DNA (ZymoBIOMICS -Microbial Community DNA), or ii) standard DNA prepared in-house; this consisted of equimolarly pooled DNA extracted from 11 bacterial isolates (Bacteroides fragilis, Haemophilus ...
(2016). Bacteroides fragilis type VI secretion systems use novel effector and immunity proteins to antagonize human gut Bacteroidales species. Proc Natl Acad Sci USA 113: 3627–3632. Choi K-HH, Kumar A, Schweizer HP. (2006). A 10-min method for preparation of highly electrocompetent ...
inBacteroides fragilis13, albeit through an unknown mechanism. The conserved sRNA GibS is induced in the presence ofN-glycans, and binds and represses a glycoside hydrolase-encoding mRNA inBacteroides thetaiotaomicron11. Given these examples and the general importance of RNA-based regulation, it is ...
Bacteroides fragilis or Clostridium perfingen. MIC values in the range from 0.5 to 8 μg/ml have been found for mycobacteria, e.g. M. tuberculosis and atypical mycobacteria. In the in vitro test on human polymorphonuclear leucocytes and Staphylococcus aureus Strain Wood 46, sorangicin A is ...
BacteroidesAlistipesAlistipes (previously Bacteroides) are strictly anaerobic gram-negative rods that resemble the Bacteroides fragilis group in that most species are bile-resistant and indole-positive; however, they are only weakly saccharolytic and most species produce light brown pigment only on laked...
