Blood Agar Base 500grams

Blood Agar Base is a highly nutritious medium generally used as a basal medium for preparing blood agar by the addition of blood. It can also be used as general purpose medium without the addition of blood.

Blood Agar Base was used during investigations on irradiated Escherichia coli and other bacteria^1,2. It was the most suitable medium for investigating the phages of Clostridium perfringens³ and as the basis of a selective medium for Clostridium perfringens⁴. It was used with added phenolphthalein phosphate for the detection of phosphatase-producing staphylococci⁵ and with added salt and agar for the assessment of surface contamination on equipment and pig carcasses⁶. It has been used for determining the salinity range of growth of marine flavobacteria⁷.
