10. Counting Cells a. You have 18 cells in 100 Nano litters (18 cells in 0.1 microliters). What is the total of cells in 1 milliliter (ml)? b. You have a sample of RBC (Red Blood Cells). Since there are very tiny we are using only the center square in the figure. After counting under the microscope you have you find 82 cells inside the black area only. How many RBCs do you...

You have performed a serial dilution of a sample with an unknown concentration of microorganisms. You counted 55 CFU on a countable plate inoculated with 0.1 mL of a 10-3 dilution. What was the population density of the original sample per milliliter? Many of the quantitative methods discussed are popular because they enable the microbiology researcher to selectively count live cells only. Why do you think this might be an important or desirable feature in a medical or environmental research...
