Figure 1. This shows the morphological characteristics of the mixed culture of the methicillin-resistant Staphylococcus aureus and the Kocuria rosea. The figure shows how Kocuria rosea can be missed if using only nutrient agar for presumptive identification. (A) Mixed culture of mannitol fermenting Staphylococcus aureus (yellow coloration) and non-mannitol fermenting Kocuria rosea (pink coloration) on mannitol salt agar. (B) A pure Kocuria rosea on mannitol salt agar. (C) The mixed culture on nutrient agar showing small, pale-cream colonies with the MRSA indistinguishable from the Kocuria rosea (D) Staphylococcus aureus on blood agar showing hemolysis. (E) Kocuria rosea on blood agar showing no hemolysis.
