- Explain why the media where the Staphylococcus aureus is plated has turned yellow but the media where Staphyloccocus epidermidis plated is still pink? The media used would be the Mannitol Salt Agar Medium.Gardnerella vaginalis is a gram variable rod. What type of media should be used when culturing for it? Describe the appearance of the colonies.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…
