The Human Gut Bacteria And The Human Body

If you're like many other people (including myself till I started researching this), you might only have a vague idea about what a healthy gut is. You likely know there are bacteria in your gut, that antibiotics destroy those bacteria and that you need to eat yogurt to put those bacteria back. You likely don't know you need to eat special yogurt containing active live cultures to bring bacteria back in your

More than a century ago the notion of microbiota working as a regulator for health and disease was already in use. They realized that consuming large amounts of fermented milk helped with their longevity. This began the foundation of probiotics. However, the oral probiotics that are used today are at a lower amount than what is contained in the colon. After cycling through the digestive system it is

diff. This pathogen outgrows gut commensals and releases toxins. These toxins attack the intestinal lining, causing ulcerative colitis. Since this disorder is causing many health concerns throughout hospitals and nursing homes, there are many trying to find ways to treat it. Scientists believe ulcerative colitis can be treated by introducing a new microbiota to afflicted people. Fecal microbiota transplantation or FMT is becoming increasingly accepted as a safe and effective way to treat this. FMT’s or ‘poop’ pills introduce brand new microbiota commensals from healthy individuals to those with colitis. (3) Other ways could be from multiple donors, and transplantation of one owns microbiota, extracted when in good health. Although this is still not standard therapy for the individuals, it brings to light the ability of a healthy gut microbiota in keeping individuals healthy.(4) Everyones gut microbiota is different and not all treatments will affect everyone

Is the key to disease prevention, treatment, and longevity found within us? For many illnesses pervading in American society today, our bodies may hold the answer. Each individual human has more than 100 trillion bacterial cells in their gastrointestinal tract. The commensal and mutualistic relationship between this multitude of bacteria and their host has been seen to prevent and treat disease, as well as provide insight to a long, healthy life (Koboziev, 2014). The diversity of these microorganisms and their relative abundance within the gastrointestinal tract provides protection against disease and metabolism of food (Nicholson, 2012). Due to the great diversity in gut microbiota, the composition can serve as a biological fingerprint (Sunagawa, 2013). Any significant change in an individual’s gut

Bifidobacterium bifidum is a gram positive bacteria that is anaerobic, non-spore forming, and non-motile; it is commonly found in the intestinal and vaginal mucosa of humans and animals as a part of their natural flora (3). It has also been found in human and animal feces, and beef and pork meat (2). In recent years, it has experienced a surge in popularity by not only the medical but also science community because of its abundance in natural flora. Bifidobacterium bifidum is a probiotic that has a symbiotic bacteria-host relationship by playing a beneficial role in the lower gastrointestinal tract by maintaining microbial balance by “inhibiting the growth of potential

Even when a person is living with no roomate or family they can never really be considered living alone. According to John Tuttle at ZME Science there are on average more than 7,000 different species of bacteria in a home. Bacteria are living, unicellular, prokaryotic microorganisms. There are many different species of bacteria. In fact there are around 30,000 species that have been formally named (Dykhuizen). Plus, there can be more than fifty different strains of one bacteria. Species are identified by the certain characteristics or traits of a distinct bacteria or group of bacteria, whereas strains are determined by the disease they cause or lack of disease. Bacterial pathogens are bacteria that cause disease. However, not all bacteria are pathogenic, some bacteria are non-pathogenic and are often helpful to your body. Probiotics are helpful live bacteria, they protect their host and help prevent disease. But just because you find a probiotic bacteria doesn’t mean that entire species of bacteria is probiotic. Meaning you could have both pathogenic and probiotic strains of bacteria in a single species.

In this study, the authors sought to examine the impact of certain gut microbes on body composition and metabolism. It has been previously reported that the microbial community composition is more similar between related individuals. Thus, the authors of this study used both monozygotic and dizygotic twin pairs that were “discordant” for obesity in that one of them was classified as obese while the other one was not, as a model for studying the correlation between gut microbiota and obesity and associated disorders. To do this, human fecal`microbes from each member of one of four discordant twin pairs was transplanted into mice that were germ-free. The authors also investigated which microbial taxa were more invasive, as well as the relationship between the phenotype of the host and invasiveness. They also examined how a human diet can impact on invasion and microbial niche. In order to examine this, mice that were coprophagic, meaning they consume fecal matter, were housed together.

The area of human gut microbiomics is rather new, but it represents the largest amount of DNA in the human body. Numerous studies are still underway and specifically, in regards to the neonatal gut, it is still unclear how certain bacteria would promote or help prevent the apparition of disease. (1)

Gut microbes help the stomach and small intestine when they are unable to digest certain foods we eat. It also known to aid the production of certain vitamins. Two thirds of the gut microbiome is unique to each person because of the food we eat, the air we breathe and other environmental factors.Some studies have even suggested the makeup of the gut microbiome is influenced by genes.Gut bacteria produce an array of neurochemicals that the brain uses for the regulation of physiological and mental processes, including memory, learning and mood. Gut bacteria produce an array of neurochemicals that the brain uses for the regulation of physiological and mental processes, including memory, learning and mood.In fact, 95% of the body's supply of serotonin

A standout amongst the most usually indicated advantages of the utilization of probiotics is the modulation of host immunity.In order to modulate immunity, probiotic bacteria should interact with the recognition receptors of the immune cells or that are generally delicate to probiotic-inferred items (e.g., metabolites, cell divider segments, DNA). Probiotic organisms initiate inflammatory or immune responses by interacting with epithelial cells to trigger signalling cascades which in turn stimulates underlying immune cells in the lamina propria. On the other hand, probiotics may likewise discharge solvent variables that themselves trigger signalling cascades at the level of the epithelium or related resistant framework. Moreover, probiotic organisms mediated release of soluble factors may change epithelial penetrability (16), restrain the inflammatory signalling cascade (17), or intercede initiation/development/survival of dendritic cells

Intestinal microbiota: There are trillions of bacteria in gut and around 500 different species are found. Their combined metabolic activity exceeds that of liver. They include a wide variety of host functions within and outside the git, including physiological, immunological and metabolic functions in terms of weight gain and fat distribution. Bacterial composition and activity subject to a variety of influences including host physiology, immunology, diet, antibiotic usage and enteric infections play a role in change of composition of

There is an ever-growing awareness of the possible potential for bacterial flora in the gut, also known as microbiota, to influence the gut-brain communication in health and disease.

The number food companies that are now using strains of Lactic acid bacteria and Bifidobacteria in their food products has increased considerably and it is now diary probiotic products that are making between 60%-70% of the functional food market (Mohammadi, 2012). Fermented milk and yogurt beverages are the main source of probiotics in supermarkets but there are also capsule and powder formations in addition. The popularity of these products has increased due to the number of documented benefits of consuming probiotic bacteria and support from media and marketing.

Probiotics have more benefits and uses to overall body wellness not just for gastrointestinal health, as they can:

It is an open fact that trillions of microbes reside in living organisms, where they have become a part and parcel of the human microflora or microbiome. Probiotics occurs naturally in the body because they are transferred from the mother to child through birth process. According to Probiotics America, probiotics generally thrive in colonies that adhere to local mucosa and work by promoting several body functions, from bowel
