OBJECTIVE To examine whether maternal probiotic intervention influences the alterations in the brain-immune-gut axis induced by neonatal maternal separation (MS) and/or restraint stress in adulthood (AS) in Wistar rats. DESIGN Dams had free access to drinking water supplemented with Bifidobacterium animalis subsp lactis BB-12® (3 × 10(9) CFU/mL) and Propionibacterium jensenii 702 (8.0 × 10(8)...

The results of studies on gnotobiotic and conventional animals indicate that intestinal bacteria interfere with absorption of nutrients. The microflora could exert this undesirable activity by a direct action on the gut wall or the gut function, as well as by transformation of a variety of exogenous and endogenous substances into unabsorbable or potentially toxic compounds. This short review pr...

BACKGROUND The human gut is an ecosystem consisting of a great number of commensal bacteria living in symbiosis with the host. Several data confirm that gut microbiota is engaged in a dynamic interaction with the intestinal innate and adaptive immune system, affecting different aspects of its development and function. AIM To review the immunological functions of gut microbiota and improve kno...

Inclusion of isolated fibre sources in the diet shifts nitrogen (N) excretion from urine to feces in pigs and modulates the gut microflora. As a consequence, ammonia emission decreases and gut health is improved. However, many experiments were conducted with isolated dietary fibre and very little is known on the impact of fibre when the latter still forms the cell walls of feed ingredients used...

The composition of the gut microflora has been found to play important roles in human health and disease. Some plant components, particularly dietary fibers, which are slow or non-digestible by humans, are called prebiotics because they are selectively fermented by gut bacteria resulting in specific changes in the composition and/or activity of the intestinal microbiota, thus conferring benefit...

The association of gut microflora and human health is being increasingly recognized, the impact on host well characterized, including body’s energy metabolism immune system maintenance. Several diseases, metabolic, autoimmune, obesity, hypothyroidism, intestinal disorders, are closely associated with dysbiosis. Inorganic nanoparticles (NPs) extensively utilized in numerous fields due to their d...

A single type of bacterium, tentatively identified as a member of the genus Bacillus, was isolated from 2 of 20 midguts of Douglas fir tussock moth larvae being fed a diet of fir needles. No bacteria could be isolated from most midguts. Although spherically shaped bodies were present in the food bolus, these bodies, if microorganisms, could not be distinguished from spherical bodies associated ...
