Reinforced Clostridial Medium is used for the cultivation of anaerobes from food and clinical specimens. Conforms to Harmonized USP/EP/JP Requirements in a laboratory setting. Reinforced Clostridial Medium is not intended for use in the diagnosis of disease or other conditions in humans.

Reinforced Clostridial Medium is an enriched, non-selective medium formulated by Hirsch and Grinstead. This medium was developed for the isolation of spore-forming anaerobes, especially Clostridium spp. The developers demonstrated the medium was more fertile and enabled growth to be initiated from small inocula more readily than five other media tested. Hirsch and Grinstead added Polymyxin B, 15 – 20 mg/L, to inhibit the growth of Gram-negative microorganisms.

Reinforced Clostridial Medium conforms to Harmonized United States Pharmacopoeia (USP), European Pharmacopoeia (EU), and Japanese Pharmacopoeia (JP).
