Only grows halophilic (salt-loving) bacteria. Plate on left has turned yellow, because the bacteria growing is Staph aureus, a mannitol fermenter.Plate on right also has growth, but remains pink, indicating Staph epidermidis, a non-mannitol fermenter.
What might happen if a deadly new infectious disease hit the scene?
The film "Contagion" provides an excellent opportunity to learn about infectious disease, how it spreads and which organizations would be involved in tracking and controlling a dangerous outbreak.
First lab in the series on identifying unknown bacteria. Students learn how to create a bacterial smear and preform the Gram stain, with controls and an unknown. Isolation streak plate technique also introduced.
Second lab in a series on identifying unknown bacteria. Students are introduced to the Acid-fast and Endospore stains. Specialized media (MacConkey's & Mannitol Salt) are inoculated with unknown to assist in identification of unknown bacteria using a dichotomous key.
Third lab in a series on identifying unknown bacteria. Students learn how to create controls showing various bacteria plated on MacConkeys, Mannitol Salt, Blood Agar & Tryptic Soy Agar. Students collect and interpret samples of normal flora from their own bodies.
Students test mock urine cultures of stock microbes with identities unknown to them. They choose which tests are required to identify their microbe. Students exposed to Gram staining, antibiotic sensitivity testing, api-20e strip and use of a calibrated loop and spreader.
Students learn about the cells involved in immune response, as well as antibody-antigen interaction by playing a virtual blood typing game and viewing leukocytes with the microscope.
