Bacteroides thetaiotaomicron, one of the most eminent representative gut commensal Bacteroides species, is able to use the L-fucose in host-derived and dietary polysaccharides to modify its capsular polysaccharides and glycoproteins through a mammalian ...

Comparative serology of two clinical isolates of Bacteroides fragilis and Bacteroides thetaiotaomicron [PDF]
Antiserum prepared in rabbits against Bacteroides fragilis showed numerous bands when reacted with B. fragilis antigen in Ouchterlony plates. This antiserum also reacted with Bacteroides thetaiotaomicron and showed one band of apparent identity with B. fragilis.

Nutrient-dependent morphological variability of Bacteroides thetaiotaomicron
Unique morphologies can enable bacteria to survive in their native environment. Furthermore, many bacteria change their cell shape to adapt to different environmental conditions. For instance, some bacteria increase their surface area under carbon or nitrogen starvation.

Preferential Packing of Acidic Glycosidases and Proteases into
Outer membrane vesicles (OMV) are spherical membranous structures released from the outer membrane (OM) of Gram-negative bacteria. OMV have been proposed to play several different roles during both pathogenesis and symbiosis.

Induction of chondroitin sulfate lyase activity in Bacteroides thetaiotaomicron [PDF]
Chondroitin sulfate lyase (EC 4.2.2.4) was present constitutively at low levels (0.06 to 0.08 U/mg of protein) in cells of Bacteroides thetaiotaomicron which were growing on glucose or other monosaccharides. When these uninduced bacteria were incubated with chondroitin sulfate A (5 mg/ml), chondroitin sulfate lyase specific activity increased more than

Structural and biochemical analysis of a B12 superbinder
BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

A Phase-Variable Surface Layer from the Gut Symbiont
The capsule from Bacteroides, a common gut symbiont, has long been a model system for studying the molecular mechanisms of host-symbiont interactions. The Bacteroides capsule is thought to consist of an array of phase-variable polysaccharides that give ...

The NQR Complex Regulates the Immunomodulatory Function of Bacteroides thetaiotaomicron. [PDF]
Abstract The gut microbiome and intestinal immune system are engaged in a dynamic interplay that provides myriad benefits to host health. However, the microbiome can also elicit damaging inflammatory responses, and thus establishing harmonious immune-microbiome interactions is essential to maintain homeostasis.
