Clostridial Agar is recommended for selective isolation of pathogenic Clostridia from mixed flora. Sodium thioglycollate and sodium formaldehyde sulphoxylate acts as the reducing agents. Clostridium species grows luxuriantlly on the medium. The ideal method of inoculation of Clostridial Agar is direct inoculation of sterile, cooled medium with the specimen (in tubes). Alternatively agar plates of the medium can also be inoculated by streaking.
