Question
Transcribed Image Text:ISOLATE #2
Isolation of Gram-positive Bacteria from the Nose and Skin – Part III –
Use the results from your Gram stain (morphology and Gram stain result), along with the results you record
in the table below to determine the genus of "Isolate #1" and "Isolate #2". Refer to Table 1 in “Isolation
of Gram-positive Bacteria from the Nose and Skin – Part III.
Additional Information to HELP Below!
1. MSA:
Record the results for "Isolate #2 below:
Results of Tests to determine the genera of "Isolate #2:
a. Isolate #2: Cell Morphology (shape)
Results & Interpretation
(not just positive or negative, what
do the results tell you about the
unknown bacteria?)
Appear to be rounded ball like, Bacteria is coccus shaped .
Possible genera (genus)
(there may be more than one)
Test
b. Isolate #2: Gram stain result
Gram Postive. (The color I see on my screen is purple.)
c. List at least two genera (not species) of bacteria that are consistent with the Gram reaction
and morphology you observed.
Morphology
2. Glucose Broth:
They can be Streptococcus , Enterococcus , Staphylococcus.
Gram stain result
d. Are any of these genera are normal flora on the skin? If so which one(s)?
MSA – Growth?
Normal flora are combination of many bacteria which are involved in digestion , v
(+ if there is growth or – if
there is no growth)
3. Catalase test:
MSA – Ferments mannitol?
(+ if it can; - if it can't)
Ferments glucose (+ or -)
Catalase production (+ or -)
2. What is the most likely genus of "Isolate #2"?
