•What are the characteristics of Streptococcus species? How are Staphylococcus species generally different?

•How are Streptococcus species classified? What characteristics play an important role in these classifications?

•What are some of the different tests to differentiate between Streptococcus species?

•Understand why each of these tests are used, how bacteria interact with these types of media, and how to interpret the results of these tests (i.e. what is the bile esculin test, how do bacteria interact with this media (e.g. black precipitate), and what does this tell us about the bacteria?)•Know which tests use selective vs differential medias.
