Escherichia Coli Research Paper
Bacteria may travel for a lengthy amount of time before crashing randomly with other planets or disks. If met with ideal conditions on a new planets’ surfaces, the bacteria becomes active and the process of evolution begins. In natural science, abiogenesis is the natural process by which life arises from non-living matter, such as simple organic compounds. It is a study of how biological life processes, and the method by how life on how Earth arose.
In this experiment, we cultivated an unknown specimen containing two microorganisms. The purpose of this experiment was to use a variety of biochemical test previously learned in the lab to identify the unknown bacteria. The identification of unknown bacteria is a major part of microbiology. Microbiologist observe samples such as blood and sputum in the laboratory for the presence of microorganisms. Identifying unknown bacteria is extremely important in clinical settings because it helps physicians find treatment for infections.
Enterobacteriaceae - Enterobacteriacaea is a family of gram-negative, anaerobic, rod-shaped bacteria that are usually motile and consist of saprophytes and parasites of worldwide distribution. They can be found in soil, water, plants and animals. Q2I: Mutation - Mutation is an inheritable change in the base sequence of the genome of an organism. Question Set 3: Q3A: The authors hypothesized that colistin resistance was spreading by horizontal gene transfer as opposed to mutation.
Due October 19th, 2015 Erin Gibbs: 200270053 Dr. Andrew Cameron Bio 222 Written Assignment 1 1. Health officials realized that the mysterious illness was not caused by a bacterium because the pathogen would be identified quickly in comparison to a virus, which is more complicated (CBC, 2013). 2. It was hard to identify the infectious agent because SARS presented as flu-like symptoms with a rapid onset and is similar to the common flu (CBC, 2013). People who had other underlying health problems made it difficult to identify symptoms of SARS because it made it hard to differentiate (CDC, 2013).
The bacterial DNA is circular inside of an E. coli bacterium. E coli. is most known for being found in the intestine of humans and animals but it can also be found in other places such as food
When bacteria are allowed to replicate in a petri dish and the temperature is at an optimal 37 degrees Celsius, normally cloudy patters form on the agar similar to frost on a windowpane. D'Herelle instead observed small, clear, perfectly circular spots that had formed amid the bacterial growth. He tucked away this newly acquired knowledge, and years later he discovered his proof that the phenomenon of the clear spots wasn't limited to the coccobacilli of locusts, but that bacteria pathogenic to man were equally susceptible to it when testing human stool from soldiers potentially with dysentery. To analyze what were killing the bacteria,
Introduction: Microbiology is the study of the microbial world, which is composed of microorganisms that are too tiny to be seen with a naked eye. This project demonstrates the significance of correctly identifying unknown organisms with methods and techniques acquired in the laboratory as they can make or break one's ability to accurately isolate and identify various species. Studying microbes enables oneself to have an insight on not just their structure or how they function, but how they have an impact on organisms and their environment around them as they can be found nearly anywhere. The importance of the process of identifying unknown bacteria vary from determining the causative agent of a disease, to testing if a specific food or fluid is safe to consume, and simply knowing what is present
Escherichia coli (E. coli) is normally found in living intestine of humans and animals. A bacterium that are harmless and is important to the health of the human’s intestinal tract. The intestinal tract is part of the digestive system; having varies of sizes of intestine that transport the food in order to absorb the nutrients and expel the waste. However, some E. coli are pathogenic, causing illness to the host such as diarrhea or harm the outside of the intestinal tract. The host can be effected by the consumption of contaminated water or food, or having contact with the animals or people.
Clostridium perfringens Clostridium perfringens is a bacteria which are Gram-positive, endospore-forming anaerobes, that appear to be rod-shaped. They lack flagella, but they can still migrate across surfaces using a type of gliding motility that involves the formation of filaments of bacteria lined up in an end-to-end conformation. Clostridium perfringens bacteria is most commonly found in soil, and it the intestinal tracts of humans and animals. (1,2) C. perfringens most commonly causes food poisoning, and various types of gangrene, infections from this bacteria can cause necrosis, bacteremia, and emphysematous cholecystitis. Back before the 1890’s Clostridium perfringens used to be known as Clostridium welchii.
Being able to identify unknown microbes from systematic testing is what makes the field of microbiology so important, especially in infectious disease control. Using the testing procedure laid out by the microbiology field we are able to identify unknown bacteria present in our everyday lives, and along the way learn a lot about their characteristics that separate them from other types of bacteria. Being able to do this is vital in order for us to understand why microbes are present in certain places, how they are able to grow and what restricts their growth, that way they can be combatted if necessary. These techniques for determining unknowns are also important for isolating and testing infectious disease microbes in order to prevent spreading. Another important aspect of being able to identify unknown microbes is the
Many bacteria from natural environments exist in a conglomerate and are difficult to isolate and cull from the other members of that partnership. Bacteria can be found as individual cells or in the large colonies shaped like tight coils, clusters, filaments or thin biofilms. The identification of bacteria in the laboratory is exceptionally relevant in medicine, where proper treatment is determined by isolating and classifying the bacterial species causing a given infection. The need to identify pathogens was also an impetus for advancement of clinical techniques used to identify microbes in
What is Pseudomonas? The bacteria are found in the environments like in soil, water, and plants. Pseudomonas is a bacterial infection that can occur between the natural nail plate and the nail bed and/or between an artificial nail coating and the natural nail plate. This bacterial infection can also occur in other places of the body.
Kristen Johns BIOL 2164 Disease Report 10/22/15 Klebsiella Pneumoniae Klebsiella pneumonia or also known as Friedlanders bacillus is a disease that is found in humans and animals. The genus is named after Edwin Klebs a 19th century German Microbiologist. Klebsiella begin in soil and the water on plants. K. pneumonia is found in the digestive and respiratory systems causing lobar pneumonia, meningitis, urinary tract infections, and would infections.
The putrid smell of Escherichia coli is one that is immediately identifiable to the few lucky individuals who recognize its scent. It is also an aroma with which I became intimately sensitive to as I shuttled petri dishes of the bacterium in and out of an incubator. While my classmates shied away from the task of handling the pungent bacteria used in our recombinant DNA experiments, I took to the task eagerly, anything that would take me one step closer to my goal of researching. I had the opportunity to learn about lab techniques and cutting edge biology concepts the summer before my junior year, in an extracurricular biotechnology class at Northwestern University’s Center for Talent Development. The class, a three week crash course in the
INTRODUCTION: Quick look at your hands do you see them. (attention) Do I see what you might be asking? Well the millions of bacteria that are currently hanging out on your hands.
