In a world full of bacteria, it would be logical to attempt to dispose of them when they become harmful. But what about the bacteria that digest your food, or make yogurt? Mary Roach’s essay, “Germs, Germs Everywhere. Are You Worried? Get Over It,” published in the New York Times, criticizes the fantasy of eradicating all germs by using humor, logos, and ethos. Roach’s most prominent use of creative language is humor, focusing on mocking the radical ideas of extreme germaphobes. In the first

Congressional Hearing: Helicobacter pylori, a step towards the future? The human microbiome is composed of a collection of microorganisms and their genes that inhibit the human body (SG5 Lecture 9, Feb. 6, 2018). These bacteria and microbes live on the skin, in the mouth, in the genital tract, and in the digestive tract. Their presence is essential for the regulation of different organs and their functions. The bacteria Helicobacter pylori is a microbe that lives in the acidic surroundings of the

Bacillus anthracis is a gram-positive rod bacterium that forms short chains with spores in the center of them. Bacillus anthracis causes a disease called anthrax, which is found naturally in soil and wild animals. Humans can bet infected with anthrax when they come in contact with an infected animal. Anthrax can cause severe illness but can be treated with antibiotics like penicillin, doxycycline, and ciprofloxacin. Clostridium botulinum is a gram-positive rod bacterium that forms spores and produces

In biology, in order to purify biological molecules, a common process called chromatography is often used. This process involves the separation of the large particles in the solution from the smaller particles. This is instrumental in filtering the solution, but without specialty scientific instruments, there is no way to immediately know the concentration of the, now separated, solution. However, there are multiple processes that are utilized to find unknown concentrations of a solution. One of

To begin, for this project a broth was given that contained an unknown bacterium. The purpose of this project was to use a series of tests, in order to determine what the unknown bacterium was. Using the process of elimination, an interpretation of test results was conducted, in order to rule out certain bacteria. At the end of the elimination process, it was concluded what the unknown bacterium was. Interpretation and Explanation of Results The first step was observation of the broth. At first

Four cecally-cannulated horses were utilized in a 4 x 4 Latin square to evaluate dosage levels of LIPC on the same opportunistic bacteria stated in experiment 1 and to evaluate cecal characteristics. Horses were randomly assigned to one of four treatments: 1) no LIPC, (0); 2) 15 g of 500 mg/g of LIPC, recommended level (15); 3) 25 g of 500 mg/g of LIPC (25); or 4) 35 g of 500 mg/g of LIPC (35). Horses were fed 2-3 lbs of Strategy® (Purina Mills, St. Louis, MO), once a day at 0600 and treatment was

Is it possible for Bacteriophages to effectively kill Escherichia Coli? Imagine having a severe bout of dysentery or a gangrenous foot that doctors are considering amputating. A person would choose anything at this point in order to rid themselves of their burdens. Bacteriophages are a relatively unknown solution to these problems and others. The object of the experiment (if phages can effectively kill E. Coli) is to figure out the correct dosage of bacteriophages that could be used

Bacillus anthracis is the bacterium that causes anthrax. According to the cdc.org Maret gave the first “clinical” reports of Anthrax in 1752. However, it is suggested that anthrax originated in Egypt in 700 BC (cdc.org). It was not until the 1800’s when Robert Koch wanted to discover what caused anthrax. Koch discovered that the specimens were rod-shaped bacteria. Bacillus anthracis is rod-shaped, Gram-positive bacteria, and has the ability to form endospores and are anaerobic (Bauman 695). Once

Outline Introduction * Question: Will the size and shape of our yeast colony change if different forms of nutrients were used? * The objective of our experiment is to test the effects of lactose and dextrose on yeast development. * Our hypothesis is that changing the sugar from dextrose to lactose will decrease the colonies because less carbon dioxide will be produced. Methods

What Shotgun Sequencing has uncovered about the Human Microbiome Institutional affiliation Name Date Introduction The human microbiota consists of microorganisms that live inside as well as on humans and they outnumber the human germ cells and somatic cells ten times (Turnbaugh et al. 2007). The collection of genes of these microbial organisms (the microbiome) provides the characteristics that human beings lack (Zimmer 2010). There are two major techniques that are
