a. Explain whether or not any of the methods in fi gure 2.9 could beused to determine the total number of cells present in a patient’s specimen.b. After performing the streak plate method on a bacterial specimen, theculture was incubated for 48 hours at 37°C. Upon viewing the plate, therewas heavy growth (with no isolated colonies) in the fi rst quadrant, but nogrowth was apparent in the remaining quadrants. Please discuss errors in the procedure that could have produced this result.

A serial dilution of overnight E.coli culture was performed by pipetting 1ml of a bacterial culture into a 9 ml LB medium. After this, from 10-4 and 10-5 dilution tubes 100µl were plated onto LB agar plates. Upon overnight incubation at 37°C, 200 colonies were counted in 10-4 and 22 colonies were present on 10-5 plates. How many colony-forming units were present per ml of the original culture? If the formula for CFU/ml =no. Of colonies/dilution factor*volume of culture plate

What are the possible reasons why culture plates may have too many colonies despite performing serial dilutions and OD600 readings?
If you were using the quadrant streak plate method to plate a very dilute broth culture ( with many fewer bacteria the broth used for the plate picture here), would you expect to see single, isolated colored in quadrant 4 or quadrant3? Explain your answer.
Given the illustration and values below, determine the concentration of the original sample. Report results in CFU/mL or colony-forming unit/milliliter. Note that in order to observe the accuracy of results, culture plates with countable colonies between 25-250 CFU are considered in standard bacterial plate count.

In preparing a bacterial smear for staining, heat fixation is done after the smear dries up.a.) Give the purpose of heat fixation.b.) What can be observed in wet mounts or hanging-drop slides that cannot be observed in heat-fixed slides?
assuming that serial dilution was carried out in a laboratory experiment in 6 tubes with 9 ml of saline in each tube and 0.1ml of the stock solution was used for initial dilution, pour plate method of inoculation was performed after the dilution process using 1ml of the culture from the samples from the test tubes. It was found out that on the 6th Petri dish after incubation, there was a total of 16 individual colonies counted. Compute the total number of microorganisms present in tube one, assuming that there was no human error in the transferring process.

How would you make two-fold serial dilutions such that the last tube is a 1:32 dilution of the original, concentrated material? Assume that you need to have at least 500 µl of each dilution, and you should be able to perform the dilutions in microfuge tubes with a maximum capacity of 1.5 ml.
