Oxoid™ Todd Hewitt Broth (500g) is a rich, well-buffered medium specifically designed for the cultivation of Streptococcus species, particularly group A β-haemolytic streptococci, such as Streptococcus pyogenes. It is commonly used in microbiological research and clinical diagnostics, especially for the preparation of streptococci cultures for serological studies.

Key Features:

• Form: Dehydrated powder
• Weight: 500g
• Application: Cultivation of Streptococcus species, especially group A β-haemolytic streptococci, and for the production of streptococcal haemolysin
• Composition: Contains a rich blend of nutrients including fat-free minced meat infusion, tryptone, glucose, sodium bicarbonate, and disodium phosphate to support optimal growth of streptococci
• Preparation: Suspend 36.4g in 1 liter of distilled water, mix thoroughly, and autoclave at 115°C for 10 minutes
• Yield: Approximately 13.7 liters of prepared medium
• Storage: Store the dehydrated medium at 10–30°C, protected from moisture and light
• Compliance: Suitable for use in microbiological testing, particularly for the isolation and identification of Streptococcus species in clinical and research settings.
