- While working with Mannitol Salt Agar you notice the growth of staphylococci however other microorganisms are growing as well. How would you interpret this? Explain.With your tests you now figured out that your patient has a Staphylococcus infection, and you would like to know if the infection is caused by Staphylococcus aureus or by Staphylococcus epidermis. What test can you do next to see if your patient indeed has a Staphylococcus aureus infection? O You can isolate the pathogen from the patient and grow it on a mannitol salt agar. Staphylococcus aureus can ferment mannitol turning the agar plate yellow. Staphylococcus erpidermis cannot ferment mannitol and the agar plate stays red. O You can isolate the pathogen from the patient and grow it on a mannitol salt agar. Staphylococcus epidermis can ferment mannitol turning the agar plate yellow. Staphylococcus aureus cannot ferment mannitol and the agar plate stays red. O There is no way you can distinguish between Staphylococcus aureus and Staphylococcus erpidermis O you do a Gram stain. Staphylococcus aureus will stay purple as it is Gram positive and Staphylococcus erpidermis will show up as…1.
