Study Notes
- Streptococci are a type of bacteria with a specific morphology
- They are Gram positive, meaning they retain the crystal violet stain during the Gram stain process
- Their shape is ovoid, or round, and they come in chains or pairs
- They are non-motile, meaning they do not move on their own
- Some streptococci are facultative anaerobes, which means they can survive with or without oxygen, while others are obligate (strict) anaerobes, which means they only grow in the absence of oxygen.
