CASO Broth is a medium very rich in nutrients for genral use in microbiological labroratories. It supports the abundant growth of fastidious organisms such as pneumococci, streptococci, Neisseriae etc.

The medium is used frequentl in many procedures of diagnostic research or microbiology. For example, it is used for the isolation and sensitivity testing of all types of pathogens.Containing two peptones as rich nitrogen sources, obtained by the enzymatic hydrolysis of Casein and Soy proteins, this medium supports growth of a great variety of microorganisms, inclusing fastidious aerobes and anaerobes. Soy peptone also contains natural sugars which promote bacterial growth.
