Foodborne Illness – Staphylococcus • What is the infectious agent (pathogen) that causes this infectious disease? Staphylococcus is an unmodifiable bacterium that causes Botulism. Which mean that individuals have no control over catching or not catching this disease. Since botulism is such strong and dangerous bacteria‚ that ingesting the smallest amount can make individuals sick. More important is other living forms or life like bacteria’s are changing‚ and becoming resistant to the

Bacteria Prac Aim: To observe the growth of bacteria on Agar plates Hypothesis: That the bacteria will grow in colonies throughout the agar plates except for the one with the anti-biotic loop because some will fight off the bacteria. Method: (Method taken from prac sheet) Plate 1: Use the swab to cover your entire agar plate in your bacteria. You only need one swab of bacteria but be careful to cover the entire surface of your agar in a layer of bacteria. Carefully place an Antibiotic Mastring

main objective of this survey is to have a statistical data that will support the research and to put emphasis on the importance of this study. Testing method – In this method‚ the team will get sample to be tested for E. coli or Escherichia coli and Staphylococcus aureus. E. Coli normally lives in the intestines‚ where it helps the body break down and digest the food you eat. Unfortunately‚ certain types (called strains) of E. Cole can get from the intestines into the blood. This is a rare illness

Title: Chapter 7: Bacterial Growth Purpose: The purpose of this experiment is to observe the bacterial growth of Escherichia coli under various conditions. Physical factors and nutritional requirements determine the overall concentration of the bacteria. Along with the use of a spectrophotometer and the technique of serial dilution‚ countable colonies can be obtained. Results are plotted on a semi-log graph in order to observe the different growth curves corresponding to optical density (cell

and abruptly change carbon source with C12. Then I will collect four samples in different time and analyze the results from centrifugal by ultraviolet absorption. According to the hypothesis above‚ I design the experiment below. Firstly‚ Escherichia coli B will grow 14 generations at 36° C. with aeration in a glucose salts medium which is the only carbon source and labeled with C13. Then I will abruptly change the only carbon source from labeled with C13 to C12. At the same time‚ I also add ribosides

The Shiga toxin comprises a family of related protein toxins produced by bacteria Shigella dysenteriae. The bacteria S. dysenteriae was discovered by Japanese bacteriologist Kiyoshi Shiga in 1898. Shiga studied 36 patients at the Institute for Infectious Diseases (Tokyo‚ Japan) and isolated a bacterium from the intestinal tissue of dysentery patient. Bacterial isolates were cultured and fed to dogs; that resulted in dysenteric disease (Shiga‚ 1898). Shigella belongs to enterobacteriaceae bacterial

Name: Danielle Title: Unknown Lab Report Introduction: There are many reasons for identifying an unknown bacterium. The reasons range from medical purposes‚ such as determining if the unknown could cause ailments in living things or knowing what microorganisms are needed to make antibiotics. The experiment was done by applying methods in order to identify an unknown bacterium. An unknown bacterium was handed out by Dr. Honer. The appropriate tests were prepared and applied. The

starved of nutrients (glucose and nitrogen) – PHB is produced as an energy store for the bacteria. - In 1980’s Maddison University (Virgina) successfully cloned the 3 genes of A. Eutrophus that control PHB production and transferred them to Escherichia coli – an easier bacteria to work with allowing easier manipulation of the polymer depended on the need. - In 1990’s the 3 genes were cloned into sugar beets and turnips – much larger scale production of polymer.

epidermidis may cause urinary tract infections (UTIs) and infections associated with intravascular devices such as prosthetic heart valves‚ shunts‚ etc. (Bukhari‚ 2004). The second microorganism that was analyzed during this procedure was Escherichia coli. E. coli is a gram-negative and bacillus (rod-shaped) bacterium‚ that thrives in an optimum temperature of 37℃ commonly found in the intestinal tract of humans and other mammals (Cappucino and Sherman‚ 2011).. It is a facultative anaerobe that is

Abstract: The objective of the experiment is to learn how to use a microscope while viewing various types of bacteria cultures. Prepared slides are used to view bacterial cultures under a microscope that would normally be invisible to the naked eye. Bacterial shapes and arrangements or morphology are observed in prepared slides and fresh yogurt culture. Purpose: The experiment is meant to determine the shapes of bacteria under different magnifications when using a microscope; 10X‚ 40X‚ and 100X
