Discussion: The purpose of this experiment is to identify an unknown organism over three weeks by performing lab exercises that were previously performed. The unknown #16 was chosen for this experiment. During the first week, The next step in determining this unknown was to perform the streak plate method for isolation of colonies of a 24-hour period in a 37o C incubator. The unknown organism grew on the media; observed white in color, raised with a smooth margin, shiny colonies on the TSA agar

For a total of 4 weeks, the mice would be treated equally in the conditions of which they live and the contents of that they eat. After 4 weeks, each mouse’s fecal data would be collected and analyzed in terms of pH, weight, and Firmicutes to Bacteroidetes bacteria ratio. The pH of the mice’s fecal data is important because it is an easy way to determine if there is a problem with the ratio between the good and bad bacteria in the gut micro biome. In theory, the more alkaline (pH over roughly 6

Infectious and Non-infectious Disease Infectious and non-infectious diseases are two different types of diseases. Infectious disease is caused by an organism or an infective agent, known as pathogens. It can be passed from one person to another directly or indirectly where the pathogen transmits from the environment to people. Whereas, non-infectious diseases are not caused by pathogens, they are inherited. It can only be passed from generation to generation as the disease may be running in the

Dumb-Luck of Penicillin During the war of Germany, wounded soldiers were left suffering due to a lack of antibiotics that eliminated the infectious bacteria that entered their open skin. Alexander Fleming, a bacteriologist working at St. Mary’s hospital in London during 1928, may have found the cure to these infectious bacterial diseases from accidental messiness. The discovery caused for intense research in Britain which soon came to a successful end. British scientists such as Fleming, Dr. Howard

To discover my unknown, I first conducted the gram test on my species. The result was gram positive coccus. After that I did the catalase test which determines if the bacteria can breakdown hydrogen peroxide into oxygen and water. My unknown was catalase positive which lead to three genera, one of which my unknown could be. The three genera were Micrococcus, Planococcus, Staphylococcus. By doing the SIM motility test I learned that my unknown was nonmotile. With the FTM tube test I learned that my
