This is a modified Cameron Sulphite Agar with a reduced concentration of sodium sulphite from 0.1% to 0.05% to allow the growth of the more sulphite sensitive strains of clostridia. A positive result is indicated by distinct black growth throughout the media, however, this blackening is only presumptive evidence of clostridial growth. Confirmation tests must be carried out to identify the organism growing on the medium.
