Selective Agar medium used for the isolation of Gram positive staphylococci and streptococci from clinical specimens. Eliner et al. added colistin nalidixic acid to Columbia Agar to suppress the growth of gram negative bacteria. The addition of 5-10% sheep red blood cells to the base demonstrates hemolytic patterns of the staphylococci and streptococci.
