The composition of the gut microbiome also changes in severe illnesses, due not only to antibiotic use but also to such factors as ischemia of the gut, failure to eat, and immune compromise. Negative effects from this have led to interest in selective digestive tract decontamination , a treatment to kill only pathogenic bacteria and allow the re-establishment of healthy ones. Antibiotics alter the population of the microbiota in the gastrointestinal tract , and this may change the intra-community metabolic interactions, modify caloric intake by using carbohydrates, and globally affects host metabolic, hormonal and immune homeostasis. There is reasonable evidence that taking probiotics containing Lactobacillus species may help prevent antibiotic-associated diarrhea and that taking probiotics with Saccharomyces e.
The gut microbiota of a woman changes as pregnancy advances, with the changes similar to those seen in metabolic syndromes such as diabetes. The change in gut microbiota causes no ill effects. The newborn's gut microbiota resemble the mother's first-trimester samples. The diversity of the microbiome decreases from the first to third trimester, as the numbers of certain species go up. Probiotics are microorganisms that are believed to provide health benefits when consumed. Synbiotics refers to food ingredients or dietary supplements combining probiotics and prebiotics in a form of synergism. The term "pharmabiotics" is used in various ways, to mean: pharmaceutical formulations standardized manufacturing that can obtain regulatory approval as a drug of probiotics, prebiotics , or synbiotics ;  probiotics that have been genetically engineered or otherwise optimized for best performance shelf life, survival in the digestive tract, etc.
There is some evidence that treatment with some probiotic strains of bacteria may be effective in irritable bowel syndrome and chronic idiopathic constipation. Those organisms most likely to result in a decrease of symptoms have included:. Gut microbiota and exercise have recently been shown to be interconnected. Both moderate and intense exercise are typically part of the training regimen of endurance athletes, but they exert different effects on health. The interconnection between gut microbiota and endurance sports depends upon exercise intensity and training status. Bacteria in the digestive tract can contribute to and be affected by disease in various ways. The presence or overabundance of some kinds of bacteria may contribute to inflammatory disorders such as inflammatory bowel disease.
Helicobacter pylori infection can initiate formation of stomach ulcers when the bacteria penetrate the stomach epithelial lining, then causing an inflammatory phagocytotic response. Normally- commensal bacteria can harm the host if they extrude from the intestinal tract. The two main types of inflammatory bowel diseases , Crohn's disease and ulcerative colitis , are chronic inflammatory disorders of the gut; the causes of these diseases are unknown and issues with the gut flora and its relationship with the host have been implicated in these conditions.
The diversity of gut flora appears to be significantly diminished in people with inflammatory bowel diseases compared to healthy people; additionally, in people with ulcerative colitis, Proteobacteria and Actinobacteria appear to dominate; in people with Crohn's, Enterococcus faecium and several Proteobacteria appear to be over-represented. There is reasonable evidence that correcting gut flora imbalances by taking probiotics with Lactobacilli and Bifidobacteria can reduce visceral pain and gut inflammation in IBD.
Irritable bowel syndrome is a result of stress and chronic activation of the HPA axis; its symptoms include abdominal pain, changes in bowel movements, and an increase in proinflammatory cytokines. Overall, studies have found that the luminal and mucosal microbiota are changed in irritable bowel syndrome individuals, and these changes can relate to the type of irritation such as diarrhea or constipation. Also, there is a decrease in the diversity of the microbiome with low levels of fecal Lactobacilli and Bifidobacteria, high levels of facultative anaerobic bacteria such as Escherichia coli , and increased ratios of Firmicutes: Bacteroidetes.
Allergy , asthma , and diabetes mellitus are autoimmune and inflammatory disorders of unknown cause, but have been linked to imbalances in the gut flora and its relationship with the host. With asthma, two hypotheses have been posed to explain its rising prevalence in the developed world. The hygiene hypothesis posits that children in the developed world are not exposed to enough microbes and thus may contain lower prevalence of specific bacterial taxa that play protective roles. These bacterial fermentation metabolites are involved in immune signalling that prevents the triggering of asthma and lower SCFA levels are associated with the disease. The connection between the gut microbiota and diabetes mellitus type 1 has also been linked to SCFAs, such as butyrate and acetate.
Diets yielding butyrate and acetate from bacterial fermentation show increased T reg expression. The gut flora has also been implicated in obesity and metabolic syndrome due to the key role it plays in the digestive process; the Western pattern diet appears to drive and maintain changes in the gut flora that in turn change how much energy is derived from food and how that energy is used. It has generally been observed that with higher gut microbiome diversity, the microbiota will spend energy and resources on competing with other microbiota and less on manipulating the host.
The opposite is seen with lower gut microbiome diversity, and these microbiotas may work together to create host food cravings. Additionally, the liver plays a dominant role in blood glucose homeostasis by maintaining a balance between the uptake and storage of glucose through the metabolic pathways of glycogenesis and gluconeogenesis. Intestinal lipids regulate glucose homeostasis involving a gut-brain-liver axis. The direct administration of lipids into the upper intestine increases the long chain fatty acyl-coenzyme A LCFA-CoA levels in the upper intestines and suppresses glucose production even under subdiaphragmatic vagotomy or gut vagal deafferentation.
This interrupts the neural connection between the brain and the gut and blocks the upper intestinal lipids' ability to inhibit glucose production. The gut-brain-liver axis and gut microbiota composition can regulate the glucose homeostasis in the liver and provide potential therapeutic methods to treat obesity and diabetes. Just as gut flora can function in a feedback loop that can drive the development of obesity, there is evidence that restricting intake of calories i. As the liver is fed directly by the portal vein , whatever crosses the intestinal epithelium and the intestinal mucosal barrier enters the liver, as do cytokines generated there. Some genera of bacteria, such as Bacteroides and Clostridium , have been associated with an increase in tumor growth rate, while other genera, such as Lactobacillus and Bifidobacteria , are known to prevent tumor formation.
Interest in the relationship between gut flora and neuropsychiatric issues was sparked by a study showing that germ-free mice showed an exaggerated HPA axis response to stress compared to non-GF laboratory mice. A systematic review from examined the preclinical and small human trials that have been conducted with certain commercially available strains of probiotic bacteria and found that among those tested, the genera Bifidobacterium and Lactobacillus B. The composition of the human gut microbiome is similar to that of the other great apes.
In addition to humans and vertebrates, some insects also possess complex and diverse gut microbiota that play key nutritional roles. Bacterial communities associated with insects like termites and cockroaches are determined by a combination of forces, primarily diet, but there is some indication that host phylogeny may also be playing a role in the selection of lineages. For more than 51 years it has been known that the administration of low doses of antibacterial agents promotes the growth of farm animals to increase weight gain. In a study carried out on mice the ratio of Firmicutes and Lachnospiraceae was significantly elevated in animals treated with subtherapeutic doses of different antibiotics.
By analyzing the caloric content of faeces and the concentration of small chain fatty acids SCFAs in the GI tract, it was concluded that the changes in the composition of microbiota lead to an increased capacity to extract calories from otherwise indigestible constituents, and to an increased production of SCFAs. These findings provide evidence that antibiotics perturb not only the composition of the GI microbiome but also its metabolic capabilities, specifically with respect to SCFAs.

In recent years, despite the decline in the wild population, farmed fish are being harvested. It has long been known that Murray cod could be translocated to impounded water.
In the s, landholder Terence Aubrey Murray stocked a large and beautiful billabong —Murray's Lagoon just north of Lake George —with Murray cod fished out of the Molonglo River at Murray's other property of Yarralumla. At some time the billabong overflowed and introduced Murray cod into the saline lake itself. They bred rapidly, and, from the s to the s, Lake George abounded with them. In their search for water to survive in, the Murray cod flocked into the mouths of the few small creeks feeding the lake and died there by the thousands.
It commands a premium price compared to those species. It is increasing farmed, in large dams holding water used for irrigation of farmland, where the presence of effluent produced by the fish is not a problem . From Wikipedia, the free encyclopedia.
