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 red as it is Gram negative, but is stained by the counter stain.

Nutrient Growth Medium

It is a culture medium or nutrient broth for all kinds of microorganisms to grow properly and create their colony. This matrix provides support to increase the population of microbes through the method of cell proliferation. It is regarded as the food material for those organisms. It is a type of in vitro mechanism, in which the development of life is processed outside the host body. It can be solid, semi-solid, or liquid in nature. Different kinds of cells develop in different types of media.
