Background Understanding the dynamics and stability of the human gut microbiota is
important if its characterization is to play a role in the diagnosis, treatment, and prevention of …

Genetically defined in vivo models are needed to assess the importance of target cell
attachment in bacterial pathogenesis. Gastric colonization by Helicobacter pylori in human …

Colonization of germ-free mice with a normal gut microbiota elicits bacteria-specific IgA
antibody responses. The effects of these responses on microbial and host biology remain poorly …

Disrupted development of the gut microbiota is a contributing cause of childhood malnutrition.
Bifidobacterium longum subspecies infantis is a prominent early colonizer of the infant gut …

The human gut microbiota harbors three main groups of H 2 -consuming microbes: methanogens
including the dominant archaeon, Methanobrevibacter smithii, a polyphyletic group of …

Understanding how members of the human gut microbiota prioritize nutrient resources is
one component of a larger effort to decipher the mechanisms defining microbial community …

Undernutrition in children is a pressing global health problem, manifested in part by impaired
linear growth (stunting). Current nutritional interventions have been largely ineffective in …

Undernourished children in low-income countries often exhibit poor responses to oral
vaccination. Perturbed microbiota development is linked to undernutrition, but whether and how …

The adaptive immune response to the human gut microbiota consists of a complex repertoire
of antibodies interacting with a broad range of taxa. Fusing intestinal lamina propria …

Greater understanding of the spatial relationships between members of the human gut
microbiota and available nutrients is needed to gain deeper insights about community dynamics …
