What Is The Positive And Negative Results Of A Gram Negative Bacteria?

identification of an unknown bacteria. This bacteria was causing a urinary tract infection on a patient. A sample of the bacteria causing the infection was received and analyzed. The first step was to isolate the bacteria to insure that sample was free of contamination. A MAC plate, a PEA plate, along with a Nutrient agar plate where used to produce pure colonies by using the quadrant streak method on each plate. After a 24 hour incubation period the colonies where isolated. The bacteria collected was inoculated

Introduction In all areas of biology, it is easy to see that structure is related to function. This statement holds true in microbiology as well, the study of microorganisms, including bacteria.

Gram Staining: Micrococcus leteus, Escherichia coli, and Unknown Colony Ethan Hinkle Microbiology Lab 3051, Section 001 Instructor: Harrison Taylor February 9, 2015 This report represents my individual effort. I did not receive or offer aid to anyone when performing this assignment, nor did I plagiarize any material. Signed: __________________________________________________________ INTRODUCTION In 1884, Danish Physician Hans Christian Gram was in the process of developing a

_________ (50 Possible) Title: Identifying a Gram Positive and Gram Negative bacteria from a mixed broth Abstract: I inoculated a T-Soy agar with bacteria number 118, for this I used a streak isolation method. Next, in order to distinguish between Gram positive and Gram negative I used a streak isolation technique on a CNA plate, then performed the same exact procedure on a MacConkey plate. The results from the CNA plate showed the Gram Positive bacteria was an Alpha hemolyzer. Next, I used a P

microbiology were applied into learning what the unknown bacteria culture was. There were multiple procedures and test done in order to gain all the information needed to determine which bacteria was given. In order to find what the bacteria was the first step was finding the right environment and temperature that would allow the bacteria to thrive and grow. Determining this is one of the most important steps in being able to obtain conclusive results that would allow the results of the test to be accurate and

between Gram positive and Gram negative bacteria. We also used this lab to examine our mixed culture, which had been Gram stained, under the microscope. Theory and background The bacterial cell wall is the outer layer of the cell that aids in structural support and protection from the outside environment. Bacteria can be identified by the structure of their cell wall and classified into two groups known to have different cell wall types. Two of these types are referred to as the Gram positive and Gram

Antimicrobial or antibiotic resistance is a phenomenon seen when a certain microorganism (certain types of bacteria) develops a resistance for a drug that is used formerly to kill them. These resistant bacteria are emerging rapidly worldwide, affecting how a certain bacterial infection might be cured, and therefore rising a threat for patients who were treated with antibiotics a long time ago if the same type of infection. Antibiotic resistance occurred due to the overuse and misuse of a certain

Unknown Lab Report April 25th, 2006 Introduction The purpose of this lab was to identify two unknown bacteria cultures using various differential tests. The identification of these unknown cultures was accomplished by separating and differentiating possible bacteria based on specific biochemical characteristics. Whether the tests performed identified specific enzymatic reactions or metabolic pathways, each was used in a way to help recognize those specifics and identify the unknown cultures

able to isolate both the gram-negative and gram-positive bacterium. In order to obtain the correct test results and to ensure the right gram mixed unknown is identified there had to be a series of eight biochemical tests performed on the gram-negative bacterium and five biochemical tests performed on the gram-positive bacterium. Introduction The sole purpose behind this conduction was having the ability to understand just how the gram-negative and gram-positive bacteria can be distinguished and

Gram Staining Formal Lab Report Miranda King Intro Microbiology Dr. Hendrickson 13 September 2017 Purpose For the purpose of the gram staining experiment was to learn this specific type of staining technique, as well as learn how distinguish the differences between Gram positive and Gram negative stains. This technique uses crystal violet stain, Gram’s Iodine, Ethyl Alcohol, and Safranin. These dyes are used in order to distinguish between the different types of cells. For example
