You are given a mixed culture of two organisms in a small tube of TSB.
You are given a mixed culture of two organisms in a small tube of TSB. These two organisms include a Gram-negative strain (your bacterial strain to identify) and a Gram-positive strain (a contaminant). Your first task is to isolate these organisms which will help you identify which Gram-negative strain you are working with. 1) You inoculate two streak plates on TSA media and MacConkey Agar using aseptic technique. For each medium, state whether the medium is selective, differential, or neither and...

BIOL2516K Spring 2020 Week 9 Results and Homework Name 2. What does the oxidase test determine? Would you expect positive results in both aerobic and anaerobic species? 3. You accidentally mixed up the labeling of 2 pure cultures you incubated overnight. One is a Staphylococcus species and the other is a Streptococcus species. What could you do to identify the 2 tubes? Staphylococcus species are facultative anaerobes and Streptococcus species are aerotolerant anaerobes could you do to identibus species and...

You
inoculate a strain of E. coli into a broth culture and allow it to
grow. The broth medium contains three sugars: glucose, lactose, and
maltose. The strain you are growing prefers lactose to maltose. You
measured the growth by doing a viable cell count and drew a growth
curve after calculating the number of CFU/ml over time. There was
an initial lag phase, followed by an exponential phase. There was a
second lag phase of approximately 30 minutes followed...

You notice that there is an increasing prevalence of a bacterial infection at your hospital that appears to be affecting people. The bacterium has been named T. routmania, and microbiologists have found that it is a gram negative organism that is highly resistant to typical antibiotics. Immunologists have found that the organism appears to target T-cells in the host. Analysis of lymphatic fluid from infected patients has found an unusually low level of IL-2, yet tissue samples appear to have...

This week’s discussion will allow you to combine what we learned about global marketing with the product you are using for your marketing plan. Assume that you are being sent to the country you were assigned at the beginning of the module (no, you cannot change) to market the product you are using in your class marketing plan. Considering everything we have learned so far about the marketing mix, environment and other factors you need to develop a plan to...
