Blood Agar Base is a highly nutritious medium generally used as a basal medium for preparing blood agar. It can be used for the detection of phosphate producing Staphylococci by adding phenolphthalein phosphate, for assessment of surface contamination on equipment and pig carcass, by adding salt and agar and for determining salinity range of marine Flavobacteria. It can also be used for preparation of Salmonella Typhi antigens. HM peptone B and tryptose provides carbon, nitrogen, amino acids and vitamins. Sodium chloride helps in maintaining the osmotic equilibrium of the medium. Addition of blood makes the medium more nutritious by providing additional growth factors required by fastidious organisms. It also helps in visualizing the haemolytic reactions which depends on the animal blood used. Sheep blood gives best results for Group A Streptococci, but fails to support growth of Haemophilus haemolyticus since it is deficient in pyridine nucleotides. However, when horse blood is used H. haemolyticus colonies produce haemolysis and mimic Streptococcus pyogenes.
