- This is a typical lab exam question. (Problem-solving, uses current topic.)Your TA performed the antibiotic disc experiment using supplies from their research lab. The antibiotic discs had the year 2002 written on their containers.Your TA grew a pure culture of unknown bacteria. They applied the culture to a fresh agar plate and applied the 2002 antibiotic discs to the plate and incubated it for growth. They found that the mystery bacteria species was resistant to all three antibiotic discs that were applied to the plate.Are there any control groups that could be used to confirm or refute this multi-drug resistance? Describe them.New Tab HonorSociety.org C. * SpiashLearn - FUH. down your options. You may nave to go back and review the data and take a second IOOK at the data.

- A student needed to transfer bacteria from a broth culture to an agar plate. Below is the step-by-step what was done to accomplish this. The transfer of bacteria was not successful because of which step? 1. Cap of the broth culture is removed 2. The mouth of the bottle is flamed 3. The loop was flamed 4. The loop was inserted into the culture to pick up the bacteria 5. The loop was flamed 6. The loop containing the bacteria was used to introduced to spread the agar plate 7. The plate was placed in an incubator at 30 CelciusQuestion 1. Pretend you are performing an Indirect ELISA on patient to detect Streptococcus pyogenes. You did all the steps correctly, except you forgot to wash the tube before adding the substrate. How would this mistake affect your results ? Would you still be able to tell if the patient was positive or negative for S. Pyogenes?Answer True or False Dr. Soler would like to view the internal structure of the bacteria he was working on. He should use the transmission electron microscope
- What part of the test tube changes color first (in Resazurin Reduction Test)?b of 35 00:00 Bacteria In the petri dish in Figure 1, the bacteria Esherichia coli (E. coli) was grown and treated with disks soaked in different substances. Disk A was soaked in hand sanitizer, Disk B left untreated and Disk C was soaked in bleach Which disk most likely is the control disk? O A O B 10 NevtQuestions 14-16 are based on the following. In the 1940's, Avery, Macleod, and McCarty transformed nonencapsulated bacteria into encapsulated. forms by growing the nonencapsulated cells in a culture containing an extract made from dead encapsulated cells. The transformed cells produced colonies of encapsulated bacteria. Three different procedures and their results are outlined below. Procedure I: Extract made from dead encapsulated cells added to culture medium. Nonencapsulated bacteria added to culture medium. Results: Both nonencapsulated and encapsulated bacteria grow. Procedure II: Extract made from dead encapsulated cells treated with protein-degrading enzymes before adding extract to culture medium. Nonencapsulated bacteria added to culture medium. Results: Both nonencapsulated and encapsulated bacteria grow. Procedure III: Extract made from dead encapsulated cells treated with DNAse (an enzyme that selectively destroys DNA) before adding extract to culture medium.…
