The mammalian gut microbial community, known as the gut microbiota, comprises trillions of
bacteria, which co-evolved with the host and has an important role in a variety of host …

Secretory IgA has long been a divisive molecule. Some immunologists point to the mild
phenotype of IgA deficiency to justify ignoring it, while some consider its abundance and …

Probiotics are microbial strains that are beneficial to health, and their potential has recently
led to a significant increase in research interest in their use to modulate the gut microbiota …

A number of environmental factors have been associated with the development of IBD.
Alteration of the gut microbiota, or dysbiosis, is closely linked to initiation or progression of …

Background The effects of probiotic supplementation on fecal microbiota composition in
healthy adults have not been well established. We aimed to provide a systematic review of …

Vaccine-induced high-avidity IgA can protect against bacterial enteropathogens by directly
neutralizing virulence factors or by poorly defined mechanisms that physically impede …

Insect guts present distinctive environments for microbial colonization, and bacteria in the
gut potentially provide many beneficial services to their hosts. Insects display a wide range …

Antibiotic treatment failure is of growing concern. Genetically encoded resistance is key in
driving this process. However, there is increasing evidence that bacterial antibiotic …

Commensal bacteria inhabit mucosal and epidermal surfaces in mice and humans, and
have effects on metabolic and immune pathways in their hosts. Recent studies indicate that …

A dense resident microbial community in the gut, referred as the commensal microbiota,
coevolved with the host and is essential for many host physiological processes that include …
