Escherichia coli O157:H7

The Bubonic Plague is a bacteria known as Yersinia Pestis that infects the lymphatic system causing it to become inflamed (Tonsils, Adenoids, Spleen, and Thymus). The bacteria needs calcium to grow but when there is no calcium it produces amino acids called aspartic acid. Aspartic acid raises the blood plasma level of aspartate and glutamate. This excess can lead to damage of sensitive neurons. It can also help generate cellular energy, balance neurochemistry, and help the liver rid the body of…

coli, it can become very harmful for them. they can develop symptoms such as blood in their stool, diarrhea, vomiting, and stomach cramping. The symptoms can last anywhere from five to ten day. In addition to that, the incubation period for the agent is anywhere from one to ten days.4 The pathogen infects about 100,000 people yearly and of that about 3,000 have to be hospitalized and about 90 people die every year just in the United States from E. coli. 5 When reporting a…

Antibiotic Resistance Research Antibiotics have been used in the United States for many years which has led to a reduction in illness and death from infection and diseases. The over usage in farms has led to major antibiotic resistance and a public health threat. So famers need to be more careful with the way they use their antibiotics. If farmers do not use antibiotics more cautiously our public health is going to have a major health issue. Some of the things we should be concerned about is,…

In everyday life, people use antibacterial products to sanitize their homes. Some of the common active ingredients in household cleaning products are thymol, lactic acid, sodium hypochlorite, and ethanol (e.g. active ingredient in some hand sanitizers). The purpose of our experiment was to determine if antibacterial products lost effectiveness in killing common bacteria in everyday environments after repeated use. This is an important environmental issue because if these products are losing…

This lab was very helpful because it taught several important procedures needed in many fields. Basically, this lab taught us the proper general protocol to use to obtain and grow the microorganisms we took from the inside of the human mouth. It taught us how to properly stain and mount the samples we grew. Of course it taught us how to view our stained specimen under a light microscope. Grow the microorganisms we obtained was the first part of the lab. What we used to culture our…

Agarose gel electrophoresis is a lab technique that is used to separate and identify DNA and RNA according to the size of the individual molecule fragments. It has many common uses in modern molecular biology such as separation of restriction enzymes, analysis of PCR results, the number of DNA in a sample, DNA sequencing, DNA finger printing, and forensic science. The basis behind agarose gel electrophoresis is manipulating the highly negative charge held by DNA. When placed in an electric…

In the film Food Inc., director Robert Kenner, introduces the story of Kevin Kowalcyk, a 2 ½ year old who passed away from Escherichia Coli (E-Coli), which is a bacteria that can cause harmful health concerns. The E.Coli had been found in the meat of a hamburger he had eaten that was recalled. See most of us would buy a burger without thinking twice about it because we don’t think any…

The preparation for this lab should be done a week prior to examining each layer. The preparation consists of compiling the pond. To do so, obtain a small, disposable bowl with a cover. Using a thumbtack, poke holes into the lid of the container. Then, using black paper, wrap it 2/3 of the way around the bowl and proceed to the securing the black paper with aluminum foil. Once that’s completed, fill the bowl 1/4 way with soil and hay. Next, the bowl is filled with water 3/4 way. Cover the bowl,…

Water is one of Earth’s most precious resource. All living things need water. In this report we will be discussing which water is safe for drinking, how the quality of water is tested, where it is stored and collected, how it is purified and using an alternative supply to tap water. Safe water is water that will not harm you if you come in contact with it. This type of water is free from harmful micro-organisms and substances. This water would also have had to be tested and met certain…

Caenorhabditis elegans C. elegans is a nematode worm that considers as one of the simplest multicellular model organism. It is a free-living soil animal that feeds on microbes in decaying plant environments while in vitro, it mainly feeds on bacterial lawn (40). Sydney Brenner has proposed C. elegans as an experimental model organism and it has been used in biological fields, it played a huge role in the understanding and development in the knowledge about multicellular organisms since 1960s (8)…
