The article I reviewed was, "Gut Bacteria" by Megan D. Baumler PhD, RD,CD. Though there are many soucres that went into this article, Dr. Baulmer gives great insight not only on what gut bacteria is, but also how it effects our bodies and everyday life. By going into detail about how it effects everyone differently , it allows us to think more about how certain things effect us, rather then the general population. She states that the reason for this is although nutrition facts of a certain food might be correct, the way that they are reacted to by each indiviuals body is very different. Gut bacteria has been linked to things such as obesity, insulin resistance, and heart disease to name a few. As of now we are still learning a lot about gut …show more content…
It is believed that this comes down to what bacteria each person contains in their colon. Being that everyone has a great variety of colon bacteria, the differences in how our body responds to these food are vastly different. Although this is not confirmed, it is a very well known theory in the science community and is constantly under experimentation. Secondly, this article explains that not all bacteria is bad. Of course when people hear the word bacteria, they assume that is is bad for them, the very thing that they try to get rid of on a daily basis to reduce sickness. Although, some gut bacteria is very essential to us as humans. These include supporting the GI tract and immune system, while also working as a physical barrier against the harmful bacteria in your body. Finally, it is an ongoing thought among doctors and scientists that gut bacteria directly correlates to obesity. It is said to do this be effecting energy level and metabolism, which deficiancy in either one is enough to cause obesity. Although there has already been several studies that link certain gut bacteria to the cause of obesity, it is still being heavily
...indole, it is motile, there is no urease present and there is no coagulase activity. By deduction and logical reasoning Unknown 10a was determined to be Escherichia coli.
In this lab project, the microbiology students were given 2 unknown bacteria in a mixed broth each broth being numbered. The goal of this project is to determine the species of bacteria in the broth. They had to separate and isolate the bacteria from the mixed broth and ran numerous tests to identify the unknown bacteria. The significance of identifying an unknown bacteria is in a clinical setting. Determining the exact bacteria in order to prescribe the right treatment for the patient. This project is significant for a microbiology students because it gives necessary skills to them for future careers relating to clinical and research work.
The purpose of this laboratory is to learn about cultural, morphological, and biochemical characteristics that are used in identifying bacterial isolates. Besides identifying the unknown culture, students also gain an understanding of the process of identification and the techniques and theory behind the process. Experiments such as gram stain, negative stain, endospore and other important tests in identifying unknown bacteria are performed. Various chemical tests were done and the results were carefully determined to identify the unknown bacteria. First session of lab started of by the selection of an unknown bacterium then inoculations of 2 tryptic soy gar (TSA) slants, 1 nutrient broth (TSB), 1 nutrient gelatin deep, 1 motility
Jennifer Ackerman's main focus in her article The Ultimate Social Network, is that of the functions concerning bacteria within humans. Although scientists have had presumptions about humans being proficient in governing their body’s innermost structure, they soon come to recognize the sophistication of our inner space which holds an extensive plethora of bacteria and other microorganisms that lie within each and every one of us. Moreover, scientists' new and emerging view of how the human body operates, and the cause of increasing present-day diseases (i.e. obesity and different autoimmune disorders) are uncovered by analyzing effects of certain microbe species in our bodies. By italicizing on points such as the above, in conjunction with bacteria's genetic variations, and modern computing technology, the author proves that scientists are quickly progressing with the characterization the most prevalent species of microbes, which, in her opinion, is definitely paying off.
Although I have never been someone who has taken an interest in reading about nutrition and how it affects our bodies, I really enjoyed the book, Eat Dirt by Josh Axe. The author discusses how he took an interest into leaky gut after his mother was diagnosed with cancer a second time and he created a plan to help her eat healthier in order to improve her health. The plan worked wonders for his mother, although he claims the plan won’t cure her or anyone else in her case it was highly effective. Throughout the book, Axe continues to provide the reader with examples of what his patients have suffered from and how, through changing their eating habits, have improved their lives significantly. After each example of patients, the author informs the reader of what leads to leaky gut and ways to combat it. Each chapter expands on the five ways to combat leaky gut by providing examples on the topics such as, what to eat and what probiotics to take for certain conditions. Throughout his
In the last decade, the number of prescriptions for antibiotics has increases. Even though, antibiotics are helpful, an excess amount of antibiotics can be dangerous. Quite often antibiotics are wrongly prescribed to cure viruses when they are meant to target bacteria. Antibiotics are a type of medicine that is prone to kill microorganisms, or bacteria. By examining the PBS documentary Hunting the Nightmare Bacteria and the article “U.S. government taps GlaxoSmithKline for New Antibiotics” by Ben Hirschler as well as a few other articles can help depict the problem that is of doctors prescribing antibiotics wrongly or excessively, which can led to becoming harmful to the body.
Escherichia coli is a member of the family Enterobacteriaceae. It is a bacterium with a cell wall that has many components. Escherichia coli can live without oxygen which means that it is a facultative anaerobe. It is also capable of fermenting lactose under anaerobic conditions, and in the absence of alternative electron acceptors. There are effects and various factors that limit its growth rate. Its morphology consists of a rod-shaped gram negative bacteria that is commonly found in soil, water, vegetation, human intestines, as well as the intestines of animals. Its presence can be good or bad.
Bacteria play a large role in our health, the environment, and most aspects of life. They can be used in beneficial ways, such as decomposing wastes, enhancing fertilizer for crops, and breaking down of substances that our bodies cannot. However, many bacteria can also be very harmful by causing disease. Understanding how to identify bacteria has numerous applications and is incredibly important for anyone planning to enter the medical field or begin a career in research. Having the background knowledge of identifying an unknown bacteria may one day aid healthcare professionals diagnose their patient with a particular bacterial infection or help researchers determine various clinical, agricultural, and numerous other uses for bacteria.
Aside from the genetic component there is also the culture around eating in the home. Parents usually decide what type of food is eaten in the house and this in turn shapes a child’s thoughts about what is and isn’t normal. If the child is taught unhealthy eating habits from an early age it can lead to eating disorders due to the child modeling their behaviour after the parent. “Data suggest that parents, particularly mothers, may contribute to their children’s (particularly daughters’) decision to lose weight” (Module 6, slide
Through time, most renowned practitioners of alternative medicine have claimed that an unclean colon is the most dominant cause of all kinds of diseases. Without regular and proper bowl movements, the waste material that is supposed to be driven out of the body remains inside. They in turn produce toxins which are slowly absorbed by other parts of the body including the organs. This in no way can be something good for the body. In fact the toxic waste can
Genetics plays a major role in obesity; inherited genes sometimes contribute to the accumulation of fat in the body. Over 200 genes have effect on the weight having repercussions from physical activity, food choices and metabolism. Therefore, genes may increase the vulnerability of a person to become obese. Family eating patterns and social tendencies can also trigger obesity. Moreover, environmental circumstances such as availability of food high in calories and fat and the increase of the portions and combination selections in meals contribute to the development of fat accumulated for years in the body (Whitney & Rolfes, 2011, pg. 277).

Bacterial cells, like plant cells, are surrounded by a cell wall. However, bacterial cell walls are made up of polysaccharide chains linked to amino acids, while plant cell walls are made up of cellulose, which contains no amino acids. Many bacteria secrete a slimy capsule around the outside of the cell wall. The capsule provides additional protection for the cell. Many of the bacteria that cause diseases in animals are surrounded by a capsule. The capsule prevents the white blood cells and antibodies from destroying the invading bacterium. Inside the capsule and the cell wall is the cell membrane. In aerobic bacteria, the reactions of cellular respiration take place on fingerlike infoldings of the cell membrane. Ribosomes are scattered throughout the cytoplasm, and the DNA is generally found in the center of the cell. Many bacilli and spirilla have flagella, which are used for locomotion in water. A few types of bacteria that lack flagella move by gliding on a surface. However, the mechanism of this gliding motion is unknown. Most bacteria are aerobic, they require free oxygen to carry on cellular respiration. Some bacteria, called facultatibe anaerobes can live in either the presence or absence of free oxygen. They obtain energy either by aerobic respiration when oxygen is present or by fermentation when oxygen is absent. Still other bacteria cannot live in the presence of oxygen. These are called obligate anaerobes. Such bacteria obtain energy only fermentation. Through fermentation, different groups of bacteria produce a wide variety of organic compounds. Besides ethyl alcohol and lactic acid, bacterial fermentation can produce acetic acid, acetone, butyl alcohol, glycol, butyric acid, propionic acid, and methane, the main component of natural gas. Most bacteria are heterotrophic bacteria are either saprophytes or parasites. Saprophytes feed on the remains of dead plants and animals, and ordinarily do not cause disease. They release digestive enzymes onto the organic matter. The enzymes breakdown the large food molecules into smaller molecules, which are absorbed by the bacterial cells. Parasites live on or in living organisms, and may cause disease. A few types of bacteria are Autotrophic, they can synthesize the organic nutrients they require from inorganic substances. Autotrophic bacteria are either photosynthetic or Chemosynthetic. The photosynthetic bacteria contain chlorophyll that are different from the plant chlorophyll. In bacterial photosynthesis, hydrogen is obtained by the splitting of compounds other than water.
Microbes are microscopic life forms, usually too small to be seen by the naked eye. Although many microbes are single-celled, there are also numerous multi-cellular organisms. The human body has 10-100 trillion microbes living on it, making it one giant super-organism. Since the first link between microbes and diseases was made, people have been advised to wash their hands. Scientists, however, have recently started to investigate more closely how the microbes that call the human body home affect our health. While some microbes cause disease, others are more beneficial, working with our bodies in many subtle ways.
The amount of stories of inadequate foods people have consumed with sickness or even death as a result is astonishing. Having a bad experience such as getting sick after eating something would certainly create a negative thought about that food, causing one to avoid it in the future. Another common reason for not eating certain foods is for the lack of nutrients contained. There are very few foods that I don’t eat because of bad experiences; therefore, most of the foods I avoid are a result of the small amount of nutrients contained in those foods.
