Blood Agar Base No. 2 is used with blood for the isolation and cultivation of a wide variety of fastidious microorganisms. Blood Agar Base is not intended for use in the diagnosis of disease or other conditions in humans. A very rich agar base which, with the addition of blood, is capable of growing fastidious organisms. The medium gives colonial appearances, hemolysis patterns and pigment production of indicative value. When the blood is 'chocolated' the medium gives good recovery of Haemophilus spp. The medium can be made selective for various groups by the addition of appropriate antibiotic mixtures eg: streptococcus spp. colistin/oxolinic acid (X013) gardnerella spp. colistin/oxolinic acid (X011) C. perfringens neomycin (X015) (X016) staphylococcus/streptococcus spp. colistin/naladixic acid (X012).
