1 Assume you are staining a bacterial sample, and at the end of the procedure there are barely any stained cells on the slide. Interestingly, your lab partner, who used the same stock bacterial sample as you, as well as the same reagents, sees plenty of cells on their slide. Provide three possible ways you may have performed the staining procedure wrong to obtain the described results.

Step 1
Insufficient Sample: You may not have applied enough bacterial sample onto the slide. This could result in fewer cells being available to stain and therefore fewer visible cells at the end of the procedure. Show more…

You make a smear of E. coli and then simple stain the slide with methylene blue. If you failed to use correct aseptic technique by not sterilizing the loop before picking up the bacterial sample for the smear, what results may be seen under the microscope? A Both blue and purple cells may be seen on the slide. B No cells may be visible on the slide. C There may be cells of different shapes, sizes, and arrangements.

Your IA gave you two bacterial cultures to practice gram staining on. She said one of the tubes contained gram-negative and one contained gram-positive bacteria. You stained both on the same slide for comparison and saw that both your bacteria appeared pink. What could have gone wrong? Please select all that apply. - Gram-positive cells were too old. - You decolorized your slide longer than required. - Your IA has mixed up the cultures. - Gram-negative bacteria were too old. - For the primary stain, you used safranin instead of crystal violet.
