Study Notes
Streptococci Classification and Characteristics
- The main classification basis for Streptococci is based on hemolytic activity, which includes alpha-hemolytic, beta-hemolytic, and gamma-hemolytic (non-hemolytic) species.
- Streptococci are commensals and can be found in the human throat, skin, and gut.
Culture and Growth Requirements
- Most Streptococci require enriched media, such as blood agar, for culture.
- S. faecalis grows at 45°C, unlike most Streptococci which typically grow at 37°C.
Cell Wall Composition
- The cell wall of Streptococci contains teichoic acid.
