What does Methicillin-resistant Staphylococcus aureus or MRSA look like?

Answer:

Answer

It looks exactly like Staph aureus normally does - in vitro yellow domed colonies. In vivo it deopends on the site of infection. Microscopically, round, grape like clusters. You only know its MRSA when you test its resistance to Methicillin in a lab, (in vitro).
