The following are errors that people commonly make when they perform serial dilutions. Indicate whether you think that the number of cfu/ ml calculated would be too high or too low if you make this mistake. You intend to add 0.9 ml of diluent to each tube and 0.1 ml of culture. Instead, you add 0.5 ml of diluent to each tube and 0.1 ml of culture to the first tube. Then, you make a serial dilution of 0.1 ml into and from each tube as described. You prepare 0.9 ml of diluents in each tube. You add 0.1 ml of culture (from the overnight culture provided) to every tube. You add 0.9 ml of diluent to each tube. You add 0.1 ml of culture to the first tube and mix. You get distracted, and transfer 0.1 ml to the third tube instead of the second. You perform the rest of the series as described.

In the spread plate method, why is the volume plated usually limited to not more than 0.1 mL?
After performing a plate and liquid lysate, it was found that the plate lysate achieved the common titre range of 1010-1011 pfu/ml whereas the liquid lysate achieved a range of 108 PFU/mL; what is the reason for the lower titre in different methodologies? How can we troubleshoot this issue in the future?
How do you calculate the initial concentration of a sample? How would you make a 1:10 dilution of a broth culture if the final volume of the dilution is 10 ml? How much broth, and how much diluent, would you add? If you made a series of tenfold dilutions, exactly the same way as you described in question 1, what would be the dilution factor in the fifth tube?

6) 1 mL of supernatant is required for a procedure. The final colored solution proves to be too high to read accurately on the spectrophotometer. 100 μL of supernatant and 900 μL of distilled water are substituted for the original supernatant and the procedure, run as before. The reading from the standard curve is 46 mg/dL. What is the actual amount of substance in the patient serum?
Indicate whether you think that the number of cfu/ ml calculated would be too high or too low if you make this mistake. 1.You intend to add 9ml of broth (water) to each tube and 1 ml of culture. Instead, you add 5 ml of broth to each tube and 5 ml of culture to the first tube. Then, you make a serial dilution of 1 ml into and from each tube as described. 2. You prepare 9 ml of broth (water) in each tube. You add 1ml of culture of every tube. 3.You add 9 ml of broth (water) to each tube. You add 1 ml of culture to the first tube and mix. You get distracted, and transfer 1ml of the dilutant (mixture of culture and broth) to the third tube instead of the second. You perform the rest of the series as described.
What is the purpose of the RPR (RAPID PLASMA REAGIN ) Test? Why is a qualitative test performed before a semi-quantitative test? Why is it necessary to rotate the slide/card?
At the station there is a 2 mL microcentrifuge tube containing sheep blood and 3 tubes containing the following solutions: 0 mM, 300 mM, 600 mM of sucrose. The tubes are randomly labelled A, B, C. 2 mL of each solution were transferred to a different microcentrifuge tube, 20 ul of blood were then added to each tube, and they were mixed well by inverting the tube for multiple times. They were observed and it was determined whether the solution in each tube was hypotonic (Yes or No) relative to the blood cells. In addition, the solutions were diluted with water to help you determine which solution is which sucrose concentration. What sucrose concentration corresponds with each tube? Tube Hypotonic (Yes/No) Hypotonic after 1:1 dilution with water (Yes/No) Most likely Sucrose concentration (mM) A No Yes B Yes Yes C No No

Prepare 50 plates of Sheep's Blood Agar using 100mm petri dish. Add 10% of blood to the media. (Manufacturer's instructions: Suspend 38 g of blood agar base dehydrated powder in 1 liter of distilled or deionized water.) Pour 25 mL of prepared medium per plate. Express answer to the nearest whole number. How many grams of the dehydrated powder should be weighed? Answer: What is the volume of distilled water that should be used in the preparation? Answer: What is the volume of sheep's blood that should be added to the sterilized and cooled blood agar base? Answer:
