Download file to see previous pages Numerous species of bacteria are known to have evolved, grown and lived in the human intestine. Scientist such as Delzenne and Cani argue that the human gut is a habitat for between 300 and 500 different species of bacteria (277). Other scientists ascertain that the human intestine is a microbial ecosystem that contains more than 100 trillion microorganisms (Ley, Turnbaugh, Klein and Gordon 1023). The bacteria in the human gut have been linked to obesity by many research findings. This essay will investigate and report whether a person’s own natural microbial gut flora contribute to obesity. Traditionally, the key players linked to obesity have always been diet, exercise, lifestyle and one’s genes. The less one moves, the less the calories they burn and the more they are likely to eat, hence retaining a lot of calories and increasing the chances of being obese. This equation has sometimes been influenced by one’s genes. However, Simon and Gorbach (174) argue that the above mentioned factors do not adequately explain every obesity case that is reported. Researchers are continually discovering another factor that contributes to the rapid increase in one’s body weight; the bacteria in one’s gut. Until recently, the bacteria in the human gut have been ignored as potential causes of obesity. ...
Most of these microbes are scientifically proven to perform a wide range of vital bodily functions such as helping in the regulation of calories that the human body receives from food. These calories would have otherwise been stored by the body as fat; hence these microbes can simply be said to aid in the regulation of weight (Simon and Gorbach 174). According to a new study published in the International Diary Journal of Health, the particular type and balance of microbes harbored by the human body in the guts can either contribute to the body becoming lean or obese. These microbes have the capacity to manipulate themselves so as to potentially change the weight of the body (Delzenne and Cani 279). Many scientific studies conducted on mice and human volunteers have advanced the understanding of microbiomes and the effects that they have on health, obesity and metabolism. A lot of metagenomic studies have demonstrated that certain types of gut microbiota have the ability to either predispose or protect the host’s body from obesity (Turnbaugh, Ley, Mahowald, Magrini, Mardis and Gordon 1027). Through these studies, microbiota transplantations were done in germ-free murine models, revealing that the traits of obese-type gut flora which can efficiently extract energy are transmissible. These scientific studies have also shown that there are certain well known methods through which these microbiomes may a lead to obesity (Delzenne and Cani 280). These methods are through triggering systemic inflammation, promoting the deposition of fat and increasing the harvest of dietary energy. Tsai and Walter (307) suggest that future obesity treatments may require the use of prebiotics and ...Download file to see next pagesRead More

CHECK THESE SAMPLES OF Does a Persons Own Natural Microbial Gut Flora Contribute to Obesity

Gut microbiota in mammals massive comprising of bacteria, protozoans, anaerobic phycomycetes and bacteriophages. Not only are they an integral part of the gut ecosystem, but they also contribute indispensably to the nutritional, physiological and immunological functions of the gut (Mackie, 13). Though the exact composition of the gut microbiota of different animals cannot be listed with certainty, yet the variations observed are primarily due to the differences in the diet of different animals. In animals with a particular diet, the environment within the gut is more or less constant and hence the microbial population is similar (Karasov and Carey, 363)....

Factors which contribute to obesity caused by endocrine disorders, genes or some medications. Obesity is contributed by a variety of factors making it a complex health issue to address. Genetic factors, environment and one’s behavior all have an effect in causing obesity. The main cause of obesity is the intake of more calories than the amount the body can burn through physical activity. Behavior, genetic makeup and the environment have different are the main causes for calorie imbalance. An average person eats about ten million calories in ten years, but the body weight only changes by about ten pounds. This indicates that the body weight remains fairly stable over time because the...

Control of microbial growth

...are also effective in limiting microbial growth in packaged foods to prevent faster spoilage. Manufacturers of soft drinks and acidic foods use these to prolong the lifespan of foods. For example sorbic acid serves to prevent microbial growth in cheese. Other chemical food preservatives include nitrosamines, sodium nitrite and calcium propionate. Research has proved that antibiotics can be useful in preserving foodstuffs such as cheese whereby natamycin is used. Other chemical methods include the use of aldehydes, gaseous chemosterilizers and peroxides. In addition, experiential evidence points out that heavy metals and their compounds can have antimicrobial effects while in small amounts. This fact has...

Does Genetics Affect Childhood Obesity

..., with or without considering the presence of the KSR2 gene, but the reality that some people gain weight easier than others can no longer be ignored. Zhang, Tang, Wan, &Zhang (2013), in referring to genetic markers, noted the finding that “This variation between people is largely influenced by genetic factors. The discovery of a new obesity gene, KSR2, demonstrates that genes can contribute to obesity by reducing metabolic rate - how well the body burns calories” (p. 161). While this discovery is certainly not conclusive proof that certain genes result in obesity, it does certainly go a long way in pointing us in the right direction about various...

Microbial Physiology

...Ans 1a Ans b Answer b: Glucose is preferred over lactose for growth and metabolism, as it is clearly indicated in data the activity of -galactosidase induced after 10 h of growth. At this time -galactosidase will cleaved lactose to make glucose. E.coli prefers glucose over lactose and start utilizing glucose in initial stage. Once glucose gets exhausted it switches over to lactose. Similarly in case of time v/s dry weight plots it indicates biphasic (diauxic growth) growth curve. There is steady increase in dry weight as soon as culture was inoculated and reached to plateau around 10h followed by lag phase for one hour and again there is increase in dry weight. This lag phase needed for organism to switch over to new carbon source...

Does stress induced cortisol contribute to central obesity

...Does stress induced cortisol contribute to central obesity and can diet, exercise and relaxation have a positive effect? Obesity is a multidimensional disease that is increasing in prevalence, especially in the Western countries, including the United States and United Kingdom (Flegal, 2002). Many factors have been observed to be related to its etiopathogenesis. One such factor is stress. Stress is thought to influence human eating behaviour and appears to alter overall food intake in two ways, resulting in under- or overeating, which may be related to the severity of stress. Chronic life stress seems to be associated with a greater preference for energy- and nutrient-dense foods, basically those that are high in sugar and fat... ,...

Microbial Biofilms

...Assessment of the microbial biofilms begins with first and foremost sourcing and or culturing them. These can be observed in situ or can be cultured for further studies and experimentation. Caves serve as a very lucrative and accessible natural source for biofilm observation. Another natural source is dental plaque. The microbial biofilms can be grown in PVC microtiter plates and stained with crystal violet for invitro assessment in simplest measures as desThese could be cultured in laminar flows or alternatively turbulent flow systems. The continuous culture systems chemostat and turbidostat could also be used to culture the biofilms. The type of environment they are...

Gut Motility Practical assessment

...that morphine has minimal effect on ACh action. It restricts about 0.35mm only. Atropine is an inhibitor to ACh action. It is faster than ACh in occupying the muscarinic receptors. It therefore inhibits the contraction of the ileum due to its antagonistic properties. Naloxone does not exploit Muscarinic receptors. According to Gillan & Pollock (1980), it behaves like an opioid receptor antagonist. It has insignificant effect on ACh-induced contraction. Naloxone restricts morphine (morphine functions on the opioid receptor) action causing higher concentration of ACh within the synaptic region. This causes noticeable contraction. As illustrated in the graph, at 0.1nM morphine concentration, there is no notable effect. As...
