1. Compare the growth of the cultures found in Plates A, B, C and D. Which among the four plates has shown the most growth? Why do you think so?
You were tasked to prepare four petri plates. Three of the petri dishes were inoculated using different samples. The plates were prepared from the following:
Plate A: oral swab after brushing |
Plate B: cat’s paw |
Plate C: exposed in air for one hour |
Plate D: uninoculated |
The plates were incubated at 37˚C for 24 hours. The following results were obtained:
1. Compare the growth of the cultures found in Plates A, B, C and D. Which among the four plates has shown the most growth? Why do you think so?
2. Describe the appearance and abundance of the colonies found in your four plates. What possible type of microorganisms are found in your plates?
3. Although sparse, there is still visible growth of microorganisms in Plate D (uninoculated plate). Where do you think the microorganism came from?
