Which of the following is most useful to differentiate Micrococci from Staphylococci
Correct Answer: Hugh Leifson test
Description: Micrococci: gram-positive cocci which occur mostly in pairs, tetrads or irregular clusters. They are catalase and modified oxidase positive and aerobic. Non-pathogenic resemble staphylococci but in stained smears, the cells are generally larger and more gram variable than staphylococci and appear in tetrads. A common laboratory method to differentiate between micrococci and staphylococci is Hugh and Leifson's oxidation fermentation test in which micrococci show oxidative and staphylococci show fermentative patterns.
