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…

Why are live cell cultures better than preserved samples for microbial taxonomy?
