BM0947 – Muller-Kauffmann Tetrathionate Novobiocin (MKTTn) with Iodine Complete Broth

This is a selective enrichment broth for the isolation of Salmonellae spp. primarily from food and food product samples and conforms to the requirements as described in ISO 6579:2002. It can however be used in other areas including for clinical and environmental specimens. Salmonella reduce Tetrathionate and will proliferate in the medium whilst most other enteric organisms are inhibited. Unlike the older traditional Tetrathionate Broth the addition of Novobiocin (40mg/L) improves the inhibition of Proteus spp. This complete medium already includes the 2% Iodine solution that is traditionally added immediately before use.

NB:  As this is an opaque medium turbidity cannot be used as an indication of growth.
