The human gut contains a highly diverse microbial community that is essentially an open
ecosystem, despite being deeply embedded within the human body. Food-associated …

Resident gut microbes co-exist with transient bacteria to form the gut microbiota. Despite
increasing evidence suggesting a role for transient microbes on gut microbiota function, the …

The gut microbiota (GM) consists of resident commensals and transient microbes conveyed
by the diet but little is known about the role of the latter on GM homeostasis. Here we show …

Lactic acid bacteria (LAB) are present in foods, the environment and the animal gut,
although fermented foods (FFs) are recognized as the primary niche of LAB activity. Several …

The gut microbiota and its metabolic products interact with the host in many different ways,
influencing gut homoeostasis and health outcomes. The species composition of the gut …

Gastrointestinal pathogens must overcome many obstacles in order to successfully colonize
a host, not the least of which is the presence of the gut microbiota, the trillions of commensal …

ABSTRACT A diverse array of commensal microorganisms inhabits the human intestinal
tract. The most abundant and most studied members of this microbial community are …

Probiotics administered orally endure one of two fates: some merely pass through, but
others colonize the gut permanently. Although probiotics that can stably engraft in the gut …

Since the renaissance of microbiome research in the past decade, much insight has
accumulated in comprehending forces shaping the architecture and functionality of resident …

The human gut is the home of an estimated 10 18 bacterial cells, many of which are
uncharacterized or unculturable. Novel culture-independent approaches have revealed that …
