Textbook Question
Chapter 19.L1, Problem 3CSR
3. No listeria monocytogenes was discovered in the field where the cantaloupes were grown, and the original source of the bacterium in this case was never found. The FDA report on the farm made mention of a truck that was used to carry rotted or broken cantaloupe to a nearby ranch where they were fed to cattle. What could be the importance of this fact, and what steps would you take to investigate it further?

Students have asked these similar questions
1. What is the most common source of E. coli? (i.e. where does it occur naturally)
2. Why do children seem to be the most ill? (Give at least 2 reasons)
3. What is the morphology, morphological arrangement and Gram reaction of E. coli?
4. How does the E. coli strain 026:H11 damage its victims?
8. Pigment or color (e.g.: opaque, translucid, red, yellow, rose, violet, etc..) is also
another characteristic that can be used to identify your microorganism in a slant
Thus, write down the name of three microorganisms (using scientific notation:
Escherichia coli) that present a pigmented pattern of growth in a slant (write down
the color of each pigment) and the name of the disease that they may cause.

- 10. In a secret cabinet of a lab, you find two Petri dishes in storage and a mysterious lab notebook. In an effort to identify the bacteria, you run some tests (taking all necessary safety precautions) and look through the lab notebook. You find that the two Petri dishes contain the same type of nutrient medium and both bacteria seem to be Escherichia sp., but that the bacteria in plate 1 are producing large amounts of a variety of neurotoxins. The bacteria in plate 2 are not producing any major exported product. You also find this chart in the lab notebook: A E. coli growth rate (biomass/hour) Given that Strain 2 is normal E.coli (the control) and Strain 1 is a genetically engineered strain of E.coli, which line is most likely to represent strain 1, and why?

- Identifying an unknown bacterium is an essential step in the diagnosis and treatment process. Since not every antibiotic is effective against every type of bacteria, knowing what caused a particular infection allows us to make correct prescriptions so patients can recover more quickly. Knowing the cause of an infection also prevents antibiotic resistance as well, since incorrect prescriptions allow bacteria to be unnecessarily be exposed to antibiotics, increasing the chances of developing resistance.arrow_forward11. Environmental factors critical for microbial growth includes all of the following EXCEPT, Group of answer choices Growth factors Osmosis and osmotic pressure Energy source ( light) pH Temperature 12.

Your latest case is an incidence of food poisoning in a fast food restaurant. 5 people have been hospitalized for food poisoning, so you are working with that hospital to identify the source of the outbreak. Hospital clinicians have taken samples from each of the 5 patients for culturing. Each bacterial culture grew one likely microbe, each labelled P1, P2, P3, P4, and P5. All 5 isolates appear to have the same colony morphology on the plates, and all appear to be Gram-negative rods 1 micron wide and 3 microns long under the microscope. In addition, all 5 isolates appear to perform the same on an API 20E test strip that tests bacteria for 20 biochemical abilities. No other testing has been done yet. How would you best describe your set of isolates at this moment? O Each isolate is the same strain, of a different species O Each isolate is a different strain, of different species O Each isolate is a different…arrow_forward
