How can you make a final dilution of 10-10 using 5 dilution tubes? Outline your steps.
Step by step
Solved in 6 steps
- 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.How would you prepare a 1:500 dilution? You cannot use more than 10mL per tube.Observe the following Plate counts and then determine the correct number of CFU/ml Plate 1 = 564 colonies at 10^-5 dilution Plate 2 = 422 colonies at 10^-6 dilution Plate 3 = 317 colonies at 10^-7 dilution Plate 4 = 93 colonies at 10^-8 dilution 93 x 10^10 CFU/ml 9.3 x 10^-9 CFU/ml 93 x 10^9 CFU/ml 93x 10^8 CFÜ/ml 93x 10^-8 CFU/ml asap please
- 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:How would you perform a 100-fold dilution, if you want the final volume to be 15mL? What volume of sample and volume of dilute would be used?In the spread plate method, why is the volume plated usually limited to not more than 0.1 mL?
- An original sample of water containing 4.00 X 106 CFU/mL was diluted by 4 successive 1/10 dilutions. After incubation, 200 colonies were found growing on the plate. How many mLs from the last dilution tube were plated out?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?After placing sample in this instrument, what are the names of two fractions in the tube (choose all that are correct)? OPellet O Base O Supernatant O Fluid O Precipitation
- If you plate 200 ul of a 1:100,000 dilution and get 123 colonies, what is the number of CFU/mL in the original sample?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?DILUTION COLONY COUNT CFU/mL 1:106 155000 1:107 15500 1:108 1550 1:109 155 Given these values how would I fill in the rest of this serial dilution table? Also, what would be a 1:1 CFU/mL value based on this table?
