Unknown Microbiology Essay

In a non-reducing sugar 3cm cubed and 10 drops of hydrochloric acid is placed in a test tube for a water bath of 5 minutes to be mixing afterwards. Biurets reagent is added to the protein solution to determine it presence. Testing for

Although microscopic single-celled organisms inhabited earth long before humans evolved from their primate ancestors, they continue to coexist and coevolve with humans today, flourishing as both harmless and deadly companions. Within her literary work Deadly Companions: How Microbes Shaped Our History, microbiologist Dorothy Crawford begins with a dramatic account of severe acute respiratory syndrome (SARS), the first pandemic of the twenty-first century. Crawford travels back in time four billion years ago to the origin of microbes, recounting the evolutionary history of microbes, showing how microbes spread and cause epidemics, and revealing how coevolution yields host resistance. Furthermore, Crawford explores the intertwining history of microbes and humans, with the purpose to reveal the link between the emergence of microbes and the cultural development of man.

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.

For the unknown phase two project, I was assigned unknown number one. After many tests, I came to the conclusion that my unknown was Acinetobacter baumannii. It had cultural characteristics of yellow or clear colony pigmentation, smooth and translucent surface, circular form, smooth margin, and flat elevation. The unknown’s broth properties included a ring, turbidity, and sediment.

My bacterium turned out to be gram positive. When conducting these tests, I only had to do the coagulase test and the catalase test because when doing the catalase test, the reaction was that it had bubbled. If it did not bubble, or have a positive reaction, then I would not have had to do the coagulase test. Also, since my bacterium caused a positive catalase test, I only had to do the coagulase test and no other tests. This is because with staphylococcus organisms, these are the only tests

Testing for the Presence of Macromolecules in McDonald’s Happy Meals Clayton Wagoner MST Biology White 4 duPont Manual High School Introduction Carbohydrates, lipids, proteins, and nucleic acids are organic molecules found in every living organism. These macromolecules are large carbon based structures. The macromolecules are assembled by joining several smaller units, called monomers, together through a chemical reaction called dehydration synthesis. The resulting polymer can be disassembled through the complementary process called hydrolysis.

Uncontrolled Environmental conditions Atmospheric conditions The controlled variable Concentration of amylase was kept under control by measuring the amount of amylase used and also it was made sure the percentage of amylase used was 1%. The Amount of amylase/starch used were kept to 5cm3 at all times. Materials needed Beakers Bunsen burner Test tube Thermometer Stopwatch Test plate Glass rod Starch Amylase solution Water bath Iodine solution. Test tube holder Labels Marker Procedure First 5 test tubes were taken and labeled with numbers from 1 to

This can be tested by simply mixing the serum of suspected individual which contain the antibodies with the antigens of specific bacteria the accumulation of clumps confirms the presence of particular bacterial infection.[2] This test can be performed in various ways including slide agglutination reaction, tube agglutination reaction, indirect agglutination inhibition reactions etc. Another important practical application involves blood group test of

The first of these tests is the hydrogen breath test (9). This test involves a simple procedure of measuring the increase in concentration of hydrogen gas in the pulmonary excretion of hydrogen gas (refer to Figure 2 for the results of a study on patients who have undertaken this examination) (9, 6). If this increase is greater than 20 parts per million after 20g of lactose is consumed, then the patient can be identified as having lactose maldigestion (11). This method of diagnosis is widely available and a great deal more sensitive than other techniques (6). Another examination known as the lactose intolerance test, which still has quite a high sensitivity of 75%, involves undertaking a simple blood test to measure the rise in serum glucose within 60 to 120 minutes following ingestion of 50g of lactose (11).

Urinary Infection Home Remedy - How to Treat a UTI Naturally Description: You are officially some piece of the thousands who are searching for a compelling urinary infection home cure. Also, you have discovered the right article in the event that you searching for a urinary tract infection (U.T.I) treatment utilizing no anti-microbial. Body: In the event that you have been watching the news lately, you most likely have seen that numerous anti-microbial are getting unfavorable criticism.

INTRODUCTION Infection Prevention and Control (IPC) is one of the most important agents in the prevention of hospital acquired infections or what we termed nosocomial infections. IPC channels every member of the hospital, which includes, healthcare providers (HCP), patients and the hospitals perse. It is important to practice IPC commandment to every hospital as well as community. The Palestinian Ministry of Health (MOH) adopted the national IPC protocol.

Purpose: As Vibrio cholerae is one of the major causes of death in the developing world, though it is very well understood, the authors undertook the work to see if a method already relatively common to the area could be effective in reducing cholera outbreaks. The authors objectives were to find a simple method that could be used without much training to reduce the incidence of cholera. Hypothesis: The authors’ hypothesis was that if a commonly used and simple water filtration system was used to lower the amount of the waterborne copepods that are linked with Vibrio cholerae from surface water taken for daily use, the occurrence of cholera would decrease dramatically.

Section I- Introduction and Definition of a Bacterial Species Microscopic examination is essential in a microbiology lab. Scientists are able to differentiate between different organisms with the help of a microscope, because many microbes require a microscope to view very small structures such as flagellum. There are different types of microscopy, which include bright-field, phase-contrast, dark-field, fluorescence and differential interference contrast. The most common type of microscopy used in a microbiology lab is bright-field microscopy with the use of a compound microscope, which provides a contrast between the organism and the background making the organism easier to view. The ocular lens is responsible for viewing the specimen,

The study of microbiology is extremely important in my career choice. In the heath care industry it is important for us caring for those who are sick or even preventive care to teach the importance of the good that certain microbes can have. There also needs to be an understanding that not all microbes are bad, our bodies need certain microbes to stay healthy and maintain a normal flora. However, there are very many dangerous microbes that in my career choice I need to be aware of and need to be able to recognize these microbes, whether they are bacteria, pathogens, fungi, or viruses. Verifying these microbes will help determine how to treat these patients correctly and in a timely manner.
