Study Notes
Blood Agar Plate Types
- Blood agar plates contain mammalian blood, crucial for isolating difficult-to-grow organisms (fastidious organisms) and identifying hemolytic activity, particularly in Streptococcus species.
Chocolate Agar
- Chocolate agar is a modified blood agar.
- Blood cells are lysed by heating to 56°C.
- This type of agar is used to culture fastidious respiratory bacteria, like Haemophilus influenzae.
Thayer-Martin Agar
- A specialized type of chocolate agar.
- Specifically designed for isolating Neisseria gonorrheae.
Thiosulfate Citrate Bile Salts Sucrose (TCBS) Agar
- A type of agar that promotes the growth of Vibrio species, including Vibrio cholerae.
- Enhances the growth of these bacteria.
