background: increase in prevalence of obesity and type 2 diabetes which are of the main risk factors of metabolic syndrome, is not only the result of changes in genetic, diet or physical activity, but also an imbalance of micro flora may play an important role. therefore, alteration of micro flora using pre/probiotic is considered as a new strategy for treatment of metabolic disorders.   method...

This study was carried out to determine the effects of Immunogen as a prebiotic on growth-related parameters and gut micro-flora in R. kutum fry. A basal diet was formulated using common feed ingredients supplemented with Immunogen at 0, 1, 1.5, and 2 g kg-1 leading to four experimental diets.  Fish were randomly distributed in 500 L fiberglass tanks (1×1×0.5 m). The experiment lasted for eight ...

conclusions the results showed that although the human gut microbiome plays a pivotal role in health in a normal concentration, fluctuation in their number (increase or decrease) is a possible factor in the appearance of major diseases. context the composition and function of the gut microbiota develop with their host from birth. the human microbiome, especially the gut microbiota, plays a crit...

In humans, microbial colonisation of the intestine begins just after birth. However, development of the normal flora is a gradual process, which is initially determined by factors such as genetic aspects, the maternal-foetal interaction, place and mode of delivery, early feedings strategies, and the use of antibiotics. Current knowledge on the significance and impact of the gut microflora on th...

The human gastrointestinal tract is estimated to contain about l O I 4 micro-organisms, most of them in the colon. These outnumber the host’s own body cells. Considering their vast potential metabolic activity, it is inconceivable that the microbial flora will not interact extensively with man’s diet and affect body metabolism significantly. Yet relatively few micro-organisms have been studied ...

Manipulation of the human gut microflora is being attempted as a means of introducing into the digestive tract new micro-organisms which are beneficial to the host or which are able to bring about advantageous changes to the equilibrium populations and metabolic activities of the indigenous flora. In theory, this can be achieved by ingestion of nutrients or growth substances specifically favour...

An in vivo study was carried on rats to see the influence of arsenic on aerobic gut flora. A significant inhibition of gut flora was observed after 2 weeks of administration of arsenic (1 mg/L) ad libitum with a decrease in stool arsenic level and increase in liver arsenic level. However, this inhibitory effect of arsenic on gut flora was not observed in presence of vitamin E (1 mg/day) or sele...

The gastrointestinal (GI) tract represents a complex ecosystem in which a balance exists between the intestinal microflora and the host. The microflora comprises predominantly of facultative anaerobes e.g. lactobacillus and obligate anaerobes e.g. bifidobacterium. Aerobic organisms are not present in the GI tract of healthy individuals except Pseudomonas in very small numbers. Most of the gut m...
