Lactose Gelatin Medium is used for detection of Clostridium species from food samples. Members of the genus Clostridium are distributed widely in nature and are found in soil as well as in fresh water and marine water sediments throughout the world. Clostridial species are one of the major causes of food poisoning / gastro-intestinal illnesses. They are gram-positive, spore-forming rods that occur naturally in soil. Among the family are: Clostridium botulinum, which produces one of the most potent toxins in existence; Clostridium tetani, causative agent of tetanus; and Clostridium perfringens, commonly found in wound infections and diarrhoea cases. The use of toxins to damage the host is a method deployed by many bacterial pathogens including Clostridium. The medium contains lactose which is fermented by the Clostridium species, mainly by Clostridium perfringens yielding acid and gas. Phenol red is the pH indicator which turns yellow at acidic pH. Gelatin is usually liquefied by Clostridium perfringens within 24-48 hours. Disodium phosphate buffers the medium.
