Muller-Kauffmann Tetrathionate Broth, Base (ISO) is a selective enrichment of Salmonellae from various sources like milk and other food items.
Suspend 107 g of powder in 1 litre of distilled water, mix well and bring to the boil and let it cool to 40-45°C. Immediately before use add 20 ml of iodine-iodide solution prepared by dissolving 5 g of potassium iodide in 10 ml of water, adding 6 g of iodine and then diluting to 20 ml with sterile water. Also add the contents of two vials of Brilliant Green Novobiocin Selective Supplement (Cat. No. 55181) reconstituted as directed. Mix well and aseptically dispense into sterile tubes. Do not heat after adding the iodine solution. Complete medium must be used immediately; the base, without iodine, may be stored in the refrigerator for some days. White precipitate is due to calcium carbonate and is must be considered as normal.
