Intended Use: 
Tellurite Blood Agar for selective isolation and cultivation of Corynebacterium species.
Product Code: 
TM 879
Principles: 
Tellurite Blood Agar Base is used for selective isolation and cultivation of Corynebacterium species. Tellurite Blood Agar Base selective due to the presence of inhibitor and differential by means of ability of organism to reduce potassium tellurite. Corynebacterium is a genus of gram-positive, facultatively anaerobic, non-motile bacteria that exhibits a fermentative metabolism (carbohydrates to lactic acid) under certain conditions. Many species of Corynebacteria can be isolated from various places such as soil, water, blood, and human skin. Pathogenic strains of Corynebacteria can infect plants, animals, or humans. Biopeptone provides nitrogenous compounds. Sodium chloride maintains the osmotic equilibrium of the medium while phosphates buffer the medium. Corn starch neutralizes the toxic metabolites. Haemoglobin and Vitamin amino Growth Supplement stimulate good growth of Corynebacterium. Potassium tellurite acts as a selective agent and has inhibitory activity against most gram-positive and gram-negative bacteria except Corynebacterium species. C.diphtheriae reduces potassium tellurite to tellurium and thereby produce gray-black coloured colonies
