M-TETRATHIONATE BROTH BASE

Enrichment media favour the multiplication of a particular species as a step towards their isolation in pure culture. M- Tetrathionate Broth is prepared as per the formulation of Kabler and Clark for selective enrichment of Salmonella using membrane filter technique. The formulation is similar to Tetrathionate Broth except calcium carbonate. Tetrathionate Broth Base was originally described by Mueller and found that the medium selectively inhibits coliforms and permits the unrestricted growth of enteric pathogens.
