Yeasts, which have been a component of the human diet for at least 7,000 years, possess an
elaborate cell wall α-mannan. The influence of yeast mannan on the ecology of the human …

The human intestine harbors a dense microbial ecosystem (microbiota) that is different
between individuals, dynamic over time, and critical for aspects of health and disease. Dietary …

A variety of cell surface structures dictate interactions between bacteria and their environment,
including their viruses (bacteriophages). Members of the human gut Bacteroidetes …

Microbes interact with the host immune system via several potential mechanisms. One
essential step for each mechanism is the method by which intestinal microbes or their antigens …

Members of the gut-dwelling Bacteroides genus have remarkable abilities in degrading a
diverse set of fiber polysaccharide structures, most of which are found in the mammalian diet. …

When presented with nutrient mixtures, several human gut Bacteroides species exhibit
hierarchical utilization of glycans through a phenomenon that resembles catabolite repression. …

Capsular polysaccharides (CPSs) play multiple roles in protecting bacteria from host and
environmental factors, and many commensal bacteria can produce multiple capsule types. To …

This infographic on Bacteroides thetaiotaomicron (Bt) explores the ability of this microbe to
digest a broad array of complex carbohydrates, alter its surface features, and its emerging …

Our emerging view of the gut microbiome largely focuses on bacteria, while less is known
about other microbial components, such as bacteriophages (phages). Though phages are …

Bacteria express multiple diverse capsular polysaccharides (CPSs) for protection against
environmental and host factors, including the host immune system. Using a mouse TCR …
