Answer:
No, we would not use a slant culture as a source of material for preparing a wet mount or for the preparation of a sample for flagella staining, because for this preparation a fresh culture is required to be used and slant cultures are stored for days which isn't fresh and therefore, the bacteria would go in a dormant stage and the mobility would become less or get completely absent.

(a)You isolate a new pathogenic bacteria, from the sputum of a human patient, which you hypothesize was the cause of a severe respiratory infection. How could you use Koch’s postulates to prove your hypothesis? Which postulate would not be satisfied if the organism was a human-only pathogen? (b)What steps would you take to obtain a pure culture of the bacteria? What staining methods would you use to visualize the sample if you knew that the bacteria had a flagella? (c)...

You want to use Matrigel for cell culture with fibroblasts and endothelial cells (i.e., the cells would attach to it). Based on the source and composition of this material, how do you expect the cells to respond? Would the response vary for different cell types?

Suppose you would like to determine the number of bacteria in a culture via an aerobic plate count. Explain (with pictures) how you would set up a dilution series (104, 106, 10) using the fewest number of dilution blanks. Draw and label your tubes and plates with each dilution. Show all volumes including transfers, amounts in tubes, and amounts plated 1. You want to set up a 1:10 dilution series, so that you can plate a 10-1, 102, and a...

5. You use the Gram stain to try to differentiate bacteria in a sample. You find that all of the cells are Gram negative, but the teaching assistant insists there are both Gram positive and Gram negative cells present in the sample you are given. You definitely smeared a loop of the sample onto the slide and your fingers are stained a little purple and also a little red from handling the sides of the slide. Give a reason why...
