Description:
Tetrathionate Broth is recommended for the selective enrichment method of isolating Salmonella typhiand other salmonellae from faeces, sewage, etc.
Organisms which reduce tetrathionate, such as salmonellae, flourish in the medium whilst m any faecal organisms are inhibited1. Members of the Proteus group reduce tetrathionate and may consequently impair the value of this medium for the isolation of salmonellae; this disadvantage of the medium is largely overcome by the addition of 40µg of novobiocin to each millilitre of the incomplete medium before the addition of iodine 2,3.
