Principle and Interpretation
Potato Infusion HiVeg Agar is prepared by replacing Peptic digest of animal tissue and Beef extract with HiVeg peptone and HiVeg extract which are free from BSE/TSE risks. Potato Infusion HiVeg Agar is the modification of Potato Infusion Agar which is used for the isolation of Brucella species. Brucella causes zoonotic diseases with a domestic animal reservoir (1). Transmission by milk, milk products, meat and direct contact with infected animals is the usual route of exposure. This medium contains infusion of potato, HiVeg extract and HiVeg peptone which provide necessary nutrients required for the growth of Brucella. It is also used for the cultivation of Brucella species in large scale in the antigen and vaccine preparation. This medium enables Brucella species to form typical colonies and is also used for isolation from infected materials.
